Get your head in the game.....................Keep your head in the game!

You know your head isn't in the game, when you think of reasons to abandon the table when you keep losing to marginal hands. The hands are not coming your way and you can't justify playing the marginal hands most loose, as well as loose aggressive, players play just to get lucky on the flop. It's probably best to get up and walk around for a couple of orbits to clear the fog in your brain, or just leave.
Loose tables with loose aggressive players are very profitable, if you keep your head in the game. The low level games are usually loose and often loose aggressive. Loose aggressive tables are where you want to play. 



It's easy to lose focus when you aren't playing well or the hands aren't coming your way. I see a lot of players that change seats or even tables when the cards turn cold. I don't subscribe to the notion that if I change my seat, it will change my luck. You make your own luck, which is what those loose aggressive players are trying to do anyway by playing 80% of the hands and raising 50% or more with them, regardless of position. Some of them often use the straddle to build the pot. It's an action players move. I love those players, when my head is in the game. 

Keep your head in the game and raise the action players with your favorable position and range of hands and you have to know their range of hands.

What do Action Players play?
Loose Aggressive Tables average 4+ players willing to see the flop if the bets are less than 3x BB

LA players tend to bet 2x/3x BB w/Ax, Kx, Broadway connectors, IN or OUT of position.
They are not that concerned about the pot size, as most will raise to build the pot and eliminate tight players. These action players are are looking to get lucky and the only way to minimize their prospecting for luck is to attack them, especially those straddle players.

What do Tight Players play?
TA players will raise more often than Tight Passive players. Both have a similar range of hands, but neither one is a action player. The tight player is more likely to fold when the LA players raise the bet above their threshold of betting less than premium hands. 

IN position the TA players tend to call their bottom range and  raise with their top range of hands. OUT of position the TA players tend to call or raise with their top range of hands and are more dangerous than the action players which will release their hand after the flop, if they haven't hit something and/or don't have a good drawing possibility. Tight Passive and Tight Aggressive players are more likely to hold on when they hit the flop and Tight Aggressive players are more likely to raise when they hit top pair or make a set or better.

The Confusing Pot Limit Poker Bet Structure? Maybe not.....

One of my favorite games in Poker. I will usually play Pot Limit Omaha or Texas Hold'em before any other.


Pot Limit Rules
http://www.wsop.com/poker-rules/rules_nlpl.asp
Rule #6. In pot-limit, if a chip or a bill larger than the pot size is put into the pot without comment, it is considered to be a pot size bet and any excess is returned to the bettor OR if short of the pot, additional money needs to be put into the pot to make it a pot size bet.

The Bottom Line: Always announce your intended Bet, prior to moving your chips into the pot. Remember, if you don't announce "Pot" first, you'll be called on a string bet if you put the minimum bet in first, then try to add a raise to bet the Pot.. Always vocalize your intended action.

How Much?
It's sometimes hard to do the math in your head. If the pot is $424 and someone bets $68, how much can you bet? Don't waste time by attempting to calculate the answer beforehand - just announce "Pot," then figure it out, put in your call first, and then add up the total pot with all bets, adding that to your bet. (In case you're wondering, the answer here is $628.)
Easy to figure if you just multiply the last bet times 3 plus the pot, before the last bet.
68*3=204+424=628, which is the amount of your raise.
If the chips have already been added to the pot, then the last bet times 2 = the pot bet.
424+68=492 +136 = 628.
If the next person wants to raise the pot again, the new bet would be 3 times 628 (1256) + previous pot of 424 = 2309.

How you determine the maximum bet is by counting all the money in the pot and all of the bets on the table, including any call you would make before raising. (It sounds more complicated than it really is.)
You can raise any amount in between the minimum and maximum raise amounts.
Pot-Limit Hold'em is not very popular, and is mostly seen only in some large tournaments (such as the WSOP), but the Pot-Limit betting structure is used in Pot-Limit Omaha.

Pot-Limit Omaha is rapidly becoming one of the most popular poker variations, so it's a good idea to get acquainted with the Pot-Limit structure anyway.



I NEVER BLUFF


The Only Good Hand Was the Last Hand - FOLD EQUITY

The Only Good Hand Was the Last Hand - FOLD EQUITY
 

"It is the equity a player can expect to gain due to the opponent folding to his or her bets."

Folding?
It depends as much on the type of table you are at as it does the type of player you are playing, maybe more.

Most comments about any type of play center around a specific player and tends to be focused on becoming heads up after the flop, if not during the flop.

That only happens about 30%-40% of the time live and almost nonexistent on-line. Aggressiveness is the only game in town when paying on-line, but in a live cash game, aggression is sometimes fleeting, most times it's random to intermittent.

If you're at an aggressive table, there may be no real fold equity, because you are usually up against 2 to 3 villains. If you don't really know how much they have in their pocket, which you don't, you can't really tell how aggressive they are going to be. If you have watched the table, which you should have before sitting down, you can tell who is the Loose Aggressive and who is the Selective Aggressive player. Their fold equity is quite a bit different than the passive player that sits in-between them.

Essentially, fold equity is the extra amount of equity you gain when you factor in how likely your opponent is to fold. Working out the correct amount of fold equity relies heavily on your ability to read an opponent. In other words, you need to be fairly certain of your chances to get an opponent to fold. But how about 2 villains or even 3?

The formulas you read about in the most popular strategy sites are only good for a head-to-head battle.
With multiple opponents, you have to rely on multiple reads and your initial threat assessment for each villain.

A final word of warning…https://www.partypoker.com/how-to-play/school/advanced/fold-equity.html

When playing against really loose aggressive players, your fold equity will likely be close to zero. This is also the case against players with really short stacks (very few playing chips) at a cash/ring game as well as in tournaments. Short-stacked players are less likely to fold, as they need to take more risks.

“Brains Vs. Artificial Intelligence

Updated 2/11/2017
mrluckypoker Mr Lucky Poker
Artificial intelligence bot vs. the poker pros
By Noah Bierman
May 21, 2015, 3:00 a.m.

Rivers Casino in Pittsburgh
The Game. Texes Hold'em No Limit - Heads Up
14 days and 80,000 hands of no-limit Texas hold ‘em

Claudico, an AI from the same lab at Carnegie Mellon University that gave birth to Deep Blue, the computer that beat chess master Gary Kasparov.
The Pros: Jason Les, Dong Kim, Bjorn Li, and Doug Polk.

Its name, Claudico, means "I Limp" in Latin, a reference to the fact that it does not mind calling a bet in a fashion that many professional poker players believe to be weak and foolish.

The contest was part exhibition, part science experiment, and part test of humanity's limits. Lead scientist Tuomas Sandholm recruited four players recommended by top professionals to compete in a type of Texas hold 'em poker known as "heads-up, no-limit," a one-on-one game involving an especially complex array of betting strategies and choices.

The bot risked all its available chips on one hand while holding a 10 and a 5 of different suits — very bad cards — and bet big on another hand when the chances that its opponent could make a full house or a flush were great.

"It has a very sophisticated model," said Sandholm, the lead developer. "It just doesn't know that it's bluffing because it doesn't know the word 'bluff.'"
Unlike professionals, Claudico did not track its opponents' strategies. And its own game seemed random. For Brown and the other programmers, poker is the measuring stick, but not the goal.

They are really aiming to advance the field of artificial intelligence to fight cyberwars, perform negotiations and plan medical treatments, among other tasks that require complex decision-making with limited information.

Hold 'em poker, in this regard, offers a different challenge than chess or "Jeopardy!" because two cards are dealt facedown to each player; an opponent always has a large chunk of information missing. Five cards are then dealt face up for both players to use in forming their best potential poker hand.

The players beat the computer, but not by much.

Humans Out-Play an AI at Texas Hold ‘Em—For Now
http://www.wired.com/2015/05/humans-play-ai-texas-hold-em-now/
Claudico can only get close to Nash Equilibrium; it doesn’t react to the specific tendencies of individual opponents. The machine instead approximates ideal rational play, no matter the circumstances.

So the professionals adopted a constantly changing, exploitative strategy designed to locate and attack specific quirks in Claudico’s play. For example, it couldn’t process card removal—the way in which the cards in one’s own hand affect the likelihood of another player having specific card combinations. Les says that Claudico didn't factor that in, so the humans could tell when the AI was making big bets to disguise a weak hand, trying to force its opponent to fold.

That tell meant Les and his colleagues could pick off gigantic bluffs on the river by calculating that their hole cards made it unlikely Claudico had a hand as big as its bet would suggest. “It was writing a check it can’t quite cash,” says Les.

Claudico couldn't adjust to unusual bet sizing. That’s a big problem; it meant that the AI didn't always responding correctly. The humans capitalized on that. “Bjorn started using the most unusual bet sizes,” Les says. “He was falling in between the known sizes a lot, and was causing Claudico to have difficulties.”

When the final hand of the competition was completed, the players had wagered around $170 million (theoretically), and the team of humans professionals was ahead $732,713.

“While humans may still be ahead for now,” says Bowling, “it’s really just the beginning of the end.”

Poker has become one of the best ways to quantify the true power computers have in a way that is tangibly testable against a human opponent.

Unlike chess, poker is a game of incomplete information—no player has all the available data. An algorithm capable of determining optimal strategy for incomplete information scenarios could have applications for cybersecurity, medicine, and military strategy.

“Poker is now a benchmark for artificial intelligence research, just as chess once was,” said Sandholm. “It’s a game of exceeding complexity that requires a machine to make decisions based on incomplete and often misleading information, thanks to bluffing, slow play, and other decoys. And to win, the machine has to outsmart its human opponents.”


This was Heads UP poker!
How would it do at a full table or short handed 6 max or even with just two other players?

(Update)
OK, they did it again in February 2017. In the previous matchup, the pros won. The new computer named "Libratus", designed by Carnegie Mellon University, the same designers that built "Claudico". This time the computer beat (badly) 4 other professional poker players out of 1.8 million dollars (not real money though). Again, heads-up Texas Hold'em.

Let me know when it wins the main event at the WSOP against thousands of poker players.

POKER - The Liar's Game of 'Go Fish'.

Updated 2/11/2017
mrluckypoker Mr Lucky Poker

Remember the good old days as a kid and playing Go Fish with your brothers, sisters, friends and family?

Poker is the same game, but with a twist.

In the game of Go Fish, you are looking at cards in your hand and asking someone if they have one. If they do, they have to give all of them to you and if they don't then everyone else playing knows what you have in your hand and can ask for it. In the kids’ version of Go Fish, you could not lie. You could not ask for cards you did not have and they had to tell the truth. If they had some they would give them to you or tell you to "Go Fish".

Poker, on the other hand, is all about lying. The big difference is that you are not asking what specific cards someone is holding. Poker is a game where players play different ranges of cards. Loose players may play a large range of cards and tight players may play a narrow range of cards, all depending on how much they like to gamble, or how much risk their money's worth.

When you make a bet, you are actually asking a question of your opponents. If you are the first one to bet pre-flop, you are really asking the players if they can beat the range of cards you are representing. That's why poker players are fond of saying, "you don't play the cards, you play the player". No one knows what anyone else has. After a time they know pretty much which cards you like to play and how those cards may vary from position to position at the table.

If you are a tight player and everyone knows you are a tight player and you are the first to bet, you are basically telling them, "I have great cards so you had better have a monster hand to beat me".

If you are a loose player and every one knows you are a loose player, you a basically saying "I have cards I think have the potential to beat your cards, so you had better have a monster hand to beat me." You tell them this by the size of your bet and how much you believe it is the best hand or can become the best hand.

The game gets interesting according the various types of players you are playing against. Loose players gamble more and tight players gamble less, but both players have to lie from time to time. Loose players lie more, based on the fact that they are involved in lots of hands. But on a percentage basis, a tight player can actually be lying more just by playing slightly more hands.

It's even more interesting when you factor in the probability of hands into the number of liars playing a hand. If the fact that, at a full table, someone will get pocket pairs once every 16 hands, then when a normal 3 times the big blind bet is made and 2 call and one raises, then more than one person is representing that they have pocket pairs, which means that there is at least a better than 50% chance someone is lying.

Of course, poker players don't lie, they bluff! They can bluff meekly or they can be an extreme bluffer and bluff often.

After the flop is where the real art of the game comes into play. Each bet then is a series of questions about who has what and who believes what they are being told. If you believe the person who bet first had a good playable hand before the flop, is it still a winning hand after the flop?

Since the experts tell you that most hands miss the flop, then the question is which of those liars with pocket pairs will believe someone hit their hand and now their hand is beaten by a higher pair or a better made hand? And if they weren't lying, can you get them to believe you actually did hit your hand or that you really had a real pocket pair pre-flop and now you have a set or better?

The strength of the truth or lie will come in the strength of the question. And the strength of the question may be masked weakly, by a strong hand in order to get more money into the pot. The question can be asked strongly, by betting more than the other players are willing to risk and scoop up the pot now.

Of the two most common types of post flop bets, which is the truth and which is the lie? Is the PROBE BET, usually less than half the pot, really saying, "I have some of the flop, maybe not the top pair, but second pair or the nut straight or a flush draw", the truth? Is the VALUE BET, usually half the pot or more saying, "I think I have the top pair or better", the truth?

That's what makes poker so great. You get to ask the players what they have and they will tell you. It doesn't make any difference if it's the stoic old player that never talks or the brash young player that not only talks but animates the antics of an answer to the world. They do this by folding or betting. They do this by not saying a word, or by saying loudly, many words. But after the silence or the noise, comes the answer in the form of a bet or non-bet.

It usually isn't until you reach the river that you learn who bluffed or who lied and who didn't.

I think I'll start telling people to "Go Fish", more often, then make my bet or non-bet. Which will start to mean, I have a great hand so let’s go to the riverALL-IN"!

RANKING HANDS AND POINT SYSTEMS

Updated 2/11/2017
mrluckypoker Mr Lucky Poker

Let's agree that an Ace is the highest card in the deck and is worth the highest points.
There are probably as many point systems for poker as there are poker games and the various ways to play them. I think it's best to keep it simple, so I rank the Ace the highest, by about 2 points and the rest at about face value. My point system adds for pairs, connectors and suited cards, since an AA or AK should have a higher value than AT or A9 or A4.

An Ace therefore would normally be worth 12 points and a K,Q,J,T would all be worth 10.
Since Kings outrank Jacks and Tens, it should really have a higher rank than 10. and giving a higher rank also to Jacks, so we should probably give a one point advantage of Jacks over Tens, which makes a Jack worth 11, Queen worth 12 and King worth 13.
Now the ACE should have that 2 point advantage, so I'll give it 15 points.

It's hard to put a value on a pair since 22 will win heads up about 55% of the time and only 12% against a full table and beats AK. Given that a deuce has about a 2 point rank and only 4 points counting both cards, based on face value, and AK would have a value of twenty-eight (15 for the Ace and 13 for the King), we should give a factor to pairs, suited cards and connectors.
We'll start a Pair off at 20 points and add a point for card value. We will also add one point for being connected and 2 points for being suited and 3 points if it's connected and suited.

So the lowest pair (22) would equal 22 points and a pair of threes (33) would equal 23 points and a pair of nines (99) would equal 29 points and add one point higher for each broadway card; TT=30 (20+10), JJ=31 (20+11), and QQ=32 (20+12), KK=33 (20+13), and AA=35 (20+15)

22 vs AKs;
AKs = 31 points [(15+13) +1 for the connector, +2 for being suited] vs the 2 deuces @ 22 points.

If you loosly equate it to odds, then AKs would be favored 31/22 or about 1.4:1. (actually 1.409, but a tenth of a point is really no consideration in betting or looking at odds of any kind, not a factor at all, so round it up) and KK vs AKs; KK would be favored 33/31 or 1.06:1.

KK vs 22, KK favored 33/22 or 1.5:1

What's all this mean?
Only that you shouldn't bet the farm. At best, heads up you are usually about 49/51, more likely about 60/40 and at worst only a 3:1 dog, using normal odds, and normal hands for All-In bets, and the point system would only show a slight advantage, since it all changes by the river, and you can throw any point system out the window.

Favorite-to-underdog matchup Probability Odds, discounting suitability

Pair vs. 2 undercards (AA vs KQ is only slightly better than 88 vs 34)
83% to 17% or 4.9 : 1

Pair vs. lower pair (AA vs KK about the same as 88 vs 33)
82% to 18% or 4.5 : 1 

Pair vs. 1 overcard, 1 undercard (KK vs AQ not much better than 88 vs 97)
71% to 29% or 2.5 : 1

2 overcards vs. 2 undercards (AK vs QJ about the same as 98 vs 76)
63% to 37% or 1.7 : 1

Pair vs. 2 overcards (QQ vs AK and 88 vs 9T)
55% to 45% or 1.2 : 1

Max points are 35 for the AA and minimum is 6 for the 23, 5 at face value, plus 1 for being connected. In a normal counting system, many people will play any hand with 2 cards totaling 18 or higher, which would be an 8 and 10, or any pair. Aggressive players like Daniel Negreanu, will add some connectors and suited cards to their range. Some say any cards that can be connected on the flop, like one or 2 gaps, or even 3 gaps, are connectors. and look for luck to help them with a miracle flop.

This point system adds up to 3 points which lets you reasonably increase your range of cards by giving an 89 a 18 point count because it's connected, or 19 points if suited, and 20 points if it's both.

In a normal count a KK would count the same as a TT, where this system gives a better value for KK at 33 points and significantly better than the 89 which is only 3 points lower the the normal KK of 20 points.


Now a hand like JJ at 31 points against the 18 to 20 points players normally use would be 31/18 or 1.72:1.

You can use this to help decide how much to bet or raise against a normal hand if you end up heads up and in position against the range of hands people play, depending on their position. It makes your hand look stronger, because it is.

Can you use it as a betting tool on the flop?
Look at it compared to the flop rating system: A+, A, B+, etc.
How about betting about 1.72 more than the normal bet? If the normal bet is 3 times the big blind, you could make it a little more than 4.5 times the big blind (3+1.72) if you have a 31 point hand vs a normal 20 point hand. Pro's seem to like to make normal bets look different, like a $325 bet when $300 is 3 times the big blind or $16,200 when a $15,000 bet is the normal bet.

I NEVER BLUFF




Playing Pairs

The Gordon Pair Principle
A couple of things about the 2 most loved cards, the Ace and King. It's about 110 to 1 that any specific pair will be dealt, like AA or KK. It's about 220 to 1 that Kings will be beaten by Aces. If you think someone has a higher pocket pair, the odds go up about 2% to 4% for each pair from 22 to KK that your pair has been cracked. At a full table, AA will win about 35% of the time and KK will win about 31%22 wins about 12% at a full table and about 55% heads up. That being said, you should get a pocket pair once every 16 hands and putting into perspective, someone should be dealt pocket pairs once every 16 hands, or one and a half rounds at a full table.

At a full table there is about an 87% chance that at least one person has an Ace and about 70% that 2 players have an Ace and you can reduce that by about 5% for each person less than the full table. It's also about 87% that someone will have a King, or any other card you can name. AK vs AA, AK will win about 7%, at a full table and about 5% heads up. AA vs KK, AA wins about 81% heads up and about 29% at a full table. A 1% or 2% variance is a non-issue because the pot odds will be too high to consider such a small percentage.

"Gordon Pair Principlefrom Phil Gordon.

If you have 99, there are 5 higher pairs that can beat you, if there are 5 players left to act, you multiply the numbers, 5x5 = 25, then divide by 2, for 12.5, which means there is a 12.5% chance of someone beating your pairs. It's not rocket science, but something good to use when it comes down to a hard pre-flop decision.

AA (0%)
At a full table AA will win about 35% and about 88% heads up, so you need to get heads up or at least reduce the field to increase your odds of winning. Even against a Mental Midget that will go All-in pre-flop, it's a hand you don't throw away. Heads up is about the only place to slow play. You might try it if you're on the button and everyone has folded around to you. You have to re-raise on the flop, regardless of who bets.

KK (0.5% to 4.5% that someone has a higher pocket pair)
KK vs AA, KK will win about 18% at a full table and about 19% heads up. AA wins about 23% at a full table and about 81% heads up.

KK vs XX , KK wins about 30% at a full table and about 85% heads up.
You can almost play KK the same way you play AA, except there is an 87% chance at least one person has an Ace at a full table and about a 70% chance that more than one person has an Ace. Anyone with an Ace may call a normal bet and anyone with an Ace with another Broadway card is also likely to call a normal bet, or even raise. Anyone with an under pair like QQ or JJ may raise any bet. You need to reduce the field in early position and protect the KK against anyone calling with hands like an Ace with a good kicker.

QQ (1% to 9% that someone has a higher pocket pair)
QQ vs AA or KK
QQ vs AA, QQ wins about 15% at a full table and AA wins about 27%. AA wins about 81% heads up against QQ.

QQ vs KK, QQ wins about 18% at a full table and KK wins about 24%. KK wins about 81% heads up aganist QQ.

QQ vs XX, QQ wins about 26% at a full table and about 82% heads up.

JJ (1/5% to 13.5% that someone has a higher pocket pair)
JJ vs AA or KK or QQ
JJ vs AA, JJ wins about 17% at a full table and AA wins about 27% at a full table. AA wins about 81% heads up against JJ.

JJ vs KK, JJ wins about 16% at a full table and KK wins 27% about at a full table. KK wins about 81% heads up against JJ

JJ vs QQ, JJ wins about at 17% at a full table and QQ wins about 23% at a full table. QQ wins about 81% heads up against JJ.

JJ vs XX, JJ wins about 25 % at a full table and about 79% heads up.

TT (2% to 18% that someone has a higher pocket pair)
Everyone plays the Broadway cardsAKQJT. With four cards to beat you, and 5 cards to come, TT should only be played in late positions or from the blinds. Each position behind you that stays in the hand means someone has higher cards or a possible pocket pair. Each player to play in front of you could have higher cards and a higher pocket pair. Never call with TT. You have to bet. How much will depend on what bets were placed before you and how many players are left behind you.

TT vs XX, TT wins about 20% at a full table and about 77% heads up.

99 to 22 (2.5% to 54% that someone has a higher pocket pair)
Need to play them more like a drawing hand. If you don't get trips on the flop, consider folding to any normal raise. Call normal bets, but fold to bets that are more than 2x the BB.
raise that gets re-raised usually means someone at least has QQ and you should fold. It would be good to calculate the odds someone has a higher pair by using the Gordon Pair Principle.

I Never Bluff



Bluff or Semi-Bluff in No Limit Holdem? (pt 3)

Queen of Hearts

“Bluffing is a nice word for lying. The cards are going to even out in the end. In poker, the one who lies the best wins.” Chris Anderson

(Part 1) (Part 2)
Bluffing according to the flop

Most poker books say that players miss their hand on the flop. It's more likely that someone may have hit bottom pair or even more likely that a few people are on some kind of draw. Bluffing to represent a hand is easier as the lack of betting or weak betting progresses toward the button. Also the texture of the board may give someone the opportunity to represent a hand that may have missed most players.

Flops without an Ace

There is an 87% chance that at least one person at a full table has an Ace and a 76% chance that two players at a full table have an Ace. Actually there is an 87% chance that at least one person has any card you can name and 76% that two players have the same card. That being said, the lack of an Ace on the flop should mean that at least one person still in the hand has an Ace, as an overcard, because many players can not fold any Ace. As the betting moves around from early position players to late position players, a bluff can be represented that someone has paired the board and may have the Ace kicker. A single broadway card, King, Queen, Jack or Ten, can also be represented as many good players will already have mucked hands with high cards and low kickers. When the flop comes and it's 3 cards lower than a 10, if the opponent checks and you check, he is probably thinking you have an Ace, King, or Queen. If one comes, you should bet, even if you have low cards, if you think he will fold often enough for you to win.

Flops with an Ace

Knowing that there is an 87% chance that at least one person is holding an Ace and that there is a 76% chance that two people may have an Ace, as bets progress around the table toward the button, the lack of a bet gives more of an opportunity to represent the Ace that didn't hit someone's hand. Most good players aren't going to slow play even AK when the Ace hits, because there is that 76% chance someone else has an Ace and now may have 2 pair or an Ace high flush or straight draw. Everyone that has read any good poker book know the danger of allowing someone on a draw to get a free card, or even a cheap card, so there should be some betting going on, even a bluff.

Flops with a pair or better

There is only about a 2% chance that someone hit a set on the flop. Someone who did hit the set, may be slow playing the set, depending on how high it is and where they are in the betting sequence. Early position players are more likely to have hit a high set than a low set, so it's more likely they might slow play it. It's not likely that an early position player would represent a set by slow playing, more likely they could make an large bet to represent a bluff, if they have lots of chips. As the betting sequence moves around to the button, the lack of betting or weak bets could give someone the opportunity to represent the set.

There is less than a 1% chance that someone hit a straight or flush on the flop, this makes slow playing a made hand the optimal choice, unless someone has the low end. Here, a check raise, could be a good bluff against poor or weak players, or even good players if the bluff is made by a good player. Poor, weak, and tight players are not likely to make a check raise as a bluff.

A flop with trips on the board, meaning someone may have quads, will usually mean everyone, including the person with quads, is checking or making the minimum bet and only calling. It's more likely that the bets will occur on the turn and river if someone has and Ace or a full house. Probably the one hand that shouldn't have a bluff going, but if you have enough chips and the betting checks to the river, a bluff could be made.

Flops with 3 high cards

Since everyone plays the Broadway cards, it's likely someone hit something. The bluff can be made when someone makes a weak bet, suggesting a hand that can be beat. If there is no Ace on the board, an Ace can easily be represented to suggest the Nut Straight. This is one of the most dangerous bluffs to be made because the board is ripe for a Full House.

Flops with 3 of the same suit

It's about 500 to 1 that someone will hit the flush on the flop. Playing for the flush draw with anything but the Nuts is dangerous, but that's where the bluff comes in. 3 suited cards on the flop is so scary that most bets will usually be minimal, except by the Nut draws. That's where a raise or check raise could win the pot before the turn.

Bluffing against player types

If you are against an opponent who almost always calls, then you shouldn't bluff at all. If you are against an opponent who folds too much, you should bluff frequently.

Passive Players

Generally the easiest to bluff, but the one you have to give in to if they raise back and sometimes if they even call. Weak tight players are not likely to continue with the hand if they are challenged. Calling Station players have to be bet off the hand with a big bet, if they call, you are going to have to make another large bet in the hopes the Calling Station will fold. Tight players play a tighter range of cards, so bluffing is actually easier, but tight players are easier to bluff. Don't go overboard on bluffing, you still have to pick your spots. Pure bluffs can be profitable against tight player, but have to be abandoned if called or raised. You will usually only be called by players that have a top hand. Aggressive players will be able to steal the blinds, but lose more when they have a good, but not great, hand. Don't play as many drawing hands agains tight players.

Aggressive Players

Aggressive players have to be met with aggression, but are harder to bluff. “In a balance of mutual terror, whoever acts first has the advantage!” The first to bet can sometimes take the pot, unless they are up against a loose aggressive or worse, a Mental Midget. Knowing who the loose aggressive players are and who the Mental Midget is gives the advantage to a Semi-bluff that catches a hand. Aggressive players tend to be poorer players, so a good player is rarely going to bluff an aggressive player. Tighten up on semi-bluffs and losen up on legitimate hands. Against aggressive players, play more drawing hands and do not play loose with marginal hands.

I Never Bluff



Bluff or Semi-Bluff in No Limit Holdem? (pt 2)

King of Clubs

Dan Harrington’s Law on Bluffing: "The probability someone is bluffing when he shoves a big bet into the pot is at least 10%", (until the final table)
(back to Part 1)

Bluffing Pre-flop

First of all, you should rarely bluff pre-flop, unless you are one of the blinds and only one other player has bet. The only other times to consider a bluff would be at the final table or heads up. Even AA should never be slow played pre-flop, especially since there is usually at least one loose aggressive player at a table and more than one selective aggressive player. It's when there are also one or more poor players that will hold on to top hands all the way to the river that someone with AA needs to make a reasonable bet or raise. Good players aren't going to gamble pre-flop against a full table, unless they are short stacked. AA only wins about 88% of the time heads up and against a full table it only wins about 36% of the time anyway. I love it when Mental Midgets go All-in, pre-flop, on the first hand. Even the Mental Midgets that win, because other Mental Midgets follow suit, tend not to last very long.

Bluffing by Table Type

Loose Tables

Loose tables tend to have many poor players so a good player is rarely going to bluff at a loose table. In loose games, tighten up on semi-bluffs and losen up on legitimate hands. In a loose game, play more drawing hands and do not play loose with marginal hands.

Tight Tables

Tight tables tend to have more good players, so bluffing is actually easier, but good players are going to pick and choose the best time to bluff. Good players are not going to go overboard on bluffing, but there will be better bluffs going on. Pure bluffs can be profitable at a tight table, but have to be abandoned if called or raised. You will usually only be called by players that have a top hand at a tight table. Aggressive players will be able to steal the blinds, but lose more when they have a good, but not great, hand. Don't play as many drawing hands in tight games.

Bluffing by Position

Early Position

Early position hands are just too vulnerable, even with good hands, to consider a semi-bluff, unless the table is weak and/or tight. That being said, the opportunity exists to represent a top hand against weak players and/or a tight table. Accepting that the range of hands for early position is mostly the top 5 to 6 hands, you might be able to consider a semi-bluff with some of the other top 10 to 15 hands.

Middle Position

In my opinion, middle position is the worst position at the table. Middle position players are usually sandwiched between the early position top 5 or 6 hand ranges and the late position's pure strength of their position. That does give a good oppertunity to exploit a weakness shown by an early position weak bet and represent a top hand against weak late position players. Against good late position players it may be a good place to occasionally try to steal the blinds.

Late Position

First of all, you have to Semi-bluff less often if you are the last to act and have to opportunity to get a free card, because it's still about the Semi-bluff. Secondly, someone could be sandbagging. It's all about how many are still in the hand and the strength of their bets. Against weak bets, it's a good place to make a play, but analyze who is making the bet. Against weak timid players, it's a good place to test their metal. Against good players, it's representing a hand that can beat the board. With 3 or more players still in the hand, someone is sure to have a good hand, but how good. Late position is probably the best place to try Arnold Snyder's "Rochambeau" style or Blair Rodman and Lee Nelson's "Kill Phil" style. Although the button is the place where poor players try to steal the blinds, the cutoff seat just before it and the real stealing position just before the cutoff position, are where the good player try to steal the blinds and/or take down the pot.


I Never Bluff



Bluff or Semi-Bluff in No Limit Holdem? Part 1

Ace in the Hole, Mr Lucky Poker
Re-reading "The Theory of Poker" by David Sklansky.

OK, I still hate to bluff, but found out that what I really hate is the 'pure' bluff. A pure bluff is a bet, which if called, has no chance of winning in a showdown. A semi-bluff is a bet with more cards to come. A semi-bluff, when called, may not be the best hand, but has a reasonable chance of becoming the best hand. The main thing to eliminate from your game is the gamble factor, don't be a Mental Midget. There is no semi-bluff you can make on the river, with no cards to come, it's a pure bluff. Pros look for the best opportunity to maximize the value of their hand. That's why a good player is easier to bluff against than a poor player. A good player can recognize when someone may be bluffing, but because a good player will usually only semi-bluff, they can more easily represent a good hand and make it believable. A poor player will just play to the river without realizing that their hand may not be the best, but can't let it go, where a good player can fold when a reasonable bluff has been made. We need to re-evaluate when to make the semi-bluff. Playing too tight by not bluffing at some time in the game only makes your strong hands worth less in pot equity. Don't semi-bluff if you are sure you are going to be called. Betting for value is clearly incorrect when you put more money in the pot with a hand you know to be the underdog. If you think your chances of getting away with the bluff are greater than the pot odds, you should go for it. You should bet if you know the opponent will fold with enough frequency, to make the bluff profitable. It's important that bluffs are random, don't always bluff just because of the pot odds. The weaker you think your opponents hand is, the more likely your bluff will work. The stronger your opponent thinks your hand is, the more likely your bluff will work. The larger the pot, the more likely a bluff will be called.

Randomizing bluffs allows a tight player to take the thought out of the bluff. It also allows both tight players and loose aggressive players to appear to be selective aggressive players. Opponents might be able to outguess a player because they remember patterns of play. Randomizing bluffs forces them to try to outguess an uncontrolled action, which is impossible. Sklansky suggests using a card, like the King of spades as the random trigger. The normal bluffs, combined with a random bluff, are more deceptive. Sklansky even goes farther by using 5 cards which includes all four Jacks. The game he played in this example was lo-ball, like Razz, in which those high cards are generally no good to win with. Using a card in Hold'em that generally doesn't help anyone, may be a good choice. The cards would be added to the number of outs to make the hand look better to an opponent. When the random card appears on the flop, you would bet, even if it didn't help your hand. If the hand fit the board, like for a straight or flush draw, it would appear that it helped your hand. Harrington suggests using a watch with a second hand. When the second hand is between 10 and 12, you could bluff. On a digital watch you could bluff when the last second is a 9 or when it matched one of the flopped cards, duece to nine. Again, only bluff good players who may fold to a bluff and it increases your odds of winning. Even if you lose, your odds are better on the hands that do win, because you are more likely to be called by the second best hand. The opponent can never tell when you are bluffing, because it's random.

In deciding to bluff, first determine the odds of making your hand. Then determine the odds your opponent is getting on the bet. Then you must randomly bluff in such a way that the odds against your bluffing are identical to your opponent's pot odds. If you have a 20% chance of making your hand and your opponent is getting 5 to 1 odds, the ratio of your good hands, 20%, to your bluffs, should be 5 to 1. 20/5 = 4. You should bluff 4% of the time, a ratio of 20% to 4% would equal 5 to 1. If there are 10 outs, you would pick 2 unseen cards as the random bluff, to give you the 5 to 1 odds needed. It doesn't have to be exact, but the closer you are to the exact ratio the better. In game theory, when you bluff this way, you take optimum advantage of the situation.

Bluffing against 2 or more players

It's rarely correct to bluff 2 or more players when all the cards are out. The chances the bluff will succeed decrease geometrically with each player in the pot. In most bluffing situations against more than one players the probablilties that each player will fold are not independant. Position and player types have to be factored in because players who might fold in one position might not fold in another. Betting to reduce the field is not a bluff. When there is a caller ahead of you, the caller and the original bettor cannot both be bluffing. When you have a minimum to near-minimum raising hand and the player before you, who has the same standards as you, raises, then his hand is probably better than yours. It takes a better hand to call a raise than to raise a call.

Poker's Mental Midgets and the art of Russian roulette

mrluckypoker Mr Lucky Poker
Let’s play a game of Russian roulette.
You are tied to your chair and can’t get up. Here’s a gun. Here’s the barrel of the gun, six chambers, all empty. Now watch me as I put a single bullet in the gun. I close the barrel and spin it. I put a gun to your head and pull the trigger. "Click"Lucky you!

Now I'm going to pull the trigger one more time. Which would you prefer, that I spin the chamber first, or that I just pull the trigger? 

(This is actually one of the game theory settings in learning game theory, but, using one or two bullets)



Game theory is the study of strategic decision making. Specifically, it is "the study of mathematical models of conflict and cooperation between intelligent rational decision-makers." The use of game theory in the social sciences has expanded, and game theory has been applied to political, sociological, and psychological behaviors as well.

Ok, do the math, then watch 'The Deer Hunter' movie for an interesting take on the mentality of Russian roulette players, or lack there of.

Mental Midgets play poker as if they are playing Russian roulette, willing to fire or go all-in preflop, hoping that:
  • A. Everyone will fold and the Mental Midget gets to steal the blinds, which happens frequently.
  • B. They will have to go up against only one person and the Mental Midget is at worst a 4 to 1 dog, which is not usually the case because there tends to be 2 or more  Mental Midgets in the same game.
If the Mental Midget does this with one of the top 10 hands, which is also not usually the case, they are likely to be at best a 60/40 favorite, as most challengers will also have a good hand, probably at least a top 20 hand.

The problem with this strategy is that it works every time but once and the problem with Mental Midgets is that they don't know when to stop and they end up shooting themselves eventually. Worse is that since there tends to be more than one Mental Midget at the same table, the luck factor is elevated beyond 50% and you now have at least 2 dogs fighting it out. I like to call it the 'Michael Vic' factor. I really like it when there are several Mental Midgets fighting it out and 3 or 4 of them are eliminated on the first hand, since I like to play multi-table sit-n-go games.

Not to be confused with the 'Kill Phil' strategy put forth by Rodman/Nelson or 'Kill Everyone' strategy by Nelson/Streib/Lee, Mental Midgets do not have any viable plan to win the tournament anymore than those who enter a tournament only to 'sit out' for the entire tournament hoping to get 'in the money' in the end.

Poker pros rarely go All-in before the final table and even more rare is an All-in bet - preflop. It's usually because they think they have the best of it or they are at a point where their stack will be too low to make the correct bets if they are going to see their hand all the way to the river. Except for the final table, good players don't really gamble on poker and they don't use the All-in bet as a bluff, unless they can afford to lose and they will still have a decent amount of chips to get back in the game.

Oh, about Russian roulette.
Does spinning the chamber cause the chamber with the bullet to fall to the bottom due to gravity?
I read a comment that if the gun is well maintained, the extra weight of the bullet will tend to make the chamber stop with the bullet at the bottom.

In that scenario, no one would ever die. However, revolvers 'click' as they are spun because there is a ratcheting mechanism which causes drag on the spin and allows the bullet to stop - anywhere. Then the 'cocking and/or firing, ratchets the chamber for the firing pin, which will move the chamber either into or out of the correct position to properly strike the bullet casing.
