Bum Hunting

Updated 2/11/2017

Looking for Road Kill: Dead Money

Bum Hunting is looking for weak players in cash games, preferable heads-up games. I prefer to keep track of Mental Midgets. I think it's more profitable. Some extreme bum hunters just start a table and wait for the fish to come. Some will open several heads-up tables in the hopes that a fish will jump in. If you can keep good records, it may be better to join a full table where there are several fish. I like to do this with Mental Midgets at a loose table. There are sometimes several Mental Midgets who will go all-in pre-flop with marginal hands. They usually don't last long, because they do this from any position. After they have reloaded a couple of times they settle down a little and you have a good table with several fish waiting to be hooked, or trapped.

There are some players who would like to see some changes at poker sites. One suggestion came from a twoplustwo poker forum.

"Here are 2 simple/reasonable changes (poker sites) can make, either of these will solve the issue, but I'm in favor of both.
1. Allow players to change their screen name. This will make bum hunting much harder to do. No more can someone just look you up on table ratings and deny your action.
2. Only allow a small number of tables with 1 player sitting at them. Also, if a player sits down and you deny their action, you should be booted from the table instantly. If you don't want their action, you lose your table."

Regarding the first suggestion, many players like their screen name too much to change it, so it's not likely to be workable. The second one makes better since both from the bum hunter side and the fish side. If a bum hunter opens a table, any who sit can play, and if a fish opens one, the first bum hunter that finds it, gets first crack. What would really make it better would be to have a minimum of 10 to 20 big blinds set aside so a player can't just play one hand and leave.

“Brains Vs. Artificial Intelligence

Artificial intelligence bot vs. the poker pros

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.

A Beautiful Theory

Updated 2/11/2017

A Beautiful Theory (Game Theory and Poker)
Forbes 12.14.06 b Tim Harford
http://www.forbes.com/2006/12/10/business-game-theory-tech-cx_th_games06_1212harford.html

A revolution in the social sciences began in the 1920s, when the man Time magazine called "the best brain in the world" decided he would work out how to win at poker. John von Neumann's quicksilver genius accelerated the development of the atomic bomb by a year, and he was one of the fathers of the computer.

Armed with Von Neumann's mathematics, even a computer could learn when to bluff.
Real poker is hugely more complicated--and so, too, is real life. Von Neumann may have played down this objection because he and Morgenstern developed a theory of "zero sum" games, such as poker, where one player's loss is the other player's gain. If you play the optimum strategy in that sort of situation, and the other player makes mistakes, you will win. But real-life games are not usually zero-sum. It is also a reminder that in most situations, the point is not to beat some opponent but to do well for yourself. That will involve understanding the man on the other side of the game. If you think he is rational, and he isn't, your strategy will go badly wrong.

Some brilliant mathematicians and economists have worked hard to patch up these holes in the Von Neumann project, including Nobel prize winners, the most famous of them all is John Nash. Von Neumann, consumed with envy, dismissed the young Nash's result as "trivial"--meaning, mathematically simple. Sure, it was simple enough, but only (when) Nash had pointed it out. As a practical advance in game theory, it was far from trivial.

The year 2000 saw a landmark in the use of game theory. It was pure Von Neumann: a lanky computer scientist by the name of Chris "Jesus" Ferguson won the World Series of Poker using the game theoretic calculations he had developed, run on powerful, modern computers, and committed to memory.

Game theory has a lot to contribute to the analysis of life, love and economics. But the game will only go according to plan if you're sure the other fellow knows the rules. In the immortal words of Dalton from Road House, "Be nice, until it’s time NOT to be nice".

Sadly, Chris was a primary component of the Black Friday debacle.

Any Hand Will Do?

Updated 2/11/2017

The Basics.
There are 1326 two card combinations in Texas Hold'em, including suits, 169, not counting suits. Seventy-eight are Pairs (6x13). 20 Broadway (A-10) cards and 16 of them are Suited Connectors.
You should get a pair, once every 17 hands or someone should be dealt a pair once every 17 hands, that's 16:1 that someone has a pocket pair, if you don't have one. The odds are 2.67:1 that your opponent also does not have a pocket pair.
If your two cards are not a pair, but suited, it's still 118:1 that you will not hit a flush on the flop.
You can not make a straight without a 5 or a 10. The 5 and 10 are KEY cards. It's still 76:1 against someone hitting a straight on the flop.

If your two cards are not a pair, you will hit a pair on the flop, 40% of the time or  it is 60% that your opponent did not hit a pair on the flop.

There are two types of hands in Texas Hold'em. A pair or better and a draw to a straight or flush. Every hand played after the flop is a contest between these two types of hands. The draws are broken down to connected cards, gapped cards, suited connectors and suited gaped cards. Anything else isn't worth looking at execpt when you are heads-up.

This is why aggression is so important in Poker, most players do not make their hand on the flop.

In a normal Cash/Ring game, you will most likely be dealt 30 to 40 hands per hour. In Tournament play, deep stack, you should be dealt 30 to 40 hands per hour in the early stages and 25 to 30 in the middle stages, with a full table. In the later stages it could average 30 to 40 hands per hour and up to 50 hands per hour short handed to 60 hands per hour with 3 or less players.

It helps to start with a good hand.

Top 5 hands: AA, KK, QQ, AKs, AQs (26 combinations) can be played from any position. AKs, AQs, usually need to bet 3xBB in early position, 2xBB to 3xBB in middle or late position.  AA, KK, may be best to reverse the betting process. The closer to the button, the more you bet, unless everyone is folding, as if you are trying to steal the blinds. Don't fall in love with AK or AQ, they are still only drawing hands. You will only flop an A or K 33% of the time, but an Ace, King, or Queen, about 50% of the time. You will flop a flush draw only about 10% of the time.
Group 2 hands: JJ, TT, AJs, KQs, AK (29 combinations) JJ, TT, Call in early position and middle position. Can raise in late position to steal the blinds or re-raise a small bet if everyone else has called. AJs, KQs, AK, will flop a straight, flush, or pair about 50% of the time. Call from early position or middle position, raise to steal the blinds or as a probe from late position or call raises if only one other person has raised before you.
Group 3 hands: ATs, KJs, QJs, JTs, AQ (25 combinations) Always see the flop, unless there are several raisers.
Group 4 hands: KTs, QTs, J9s, T9s, 98s, AJ, KQ (38 combinations)
Limp in unless you are on the button.
Middle Low Pocket Pairs: 99, 88, 77, 66 (16 combinations) Call in middle to late position or with less than 3 players.
Low Pocket Pairs: 55, 44, 33, 22 (16 combinations) Call in late position, or with only 2 or less players in the hand.

Trap hands

Use when you have a really strong hand and someone else has a lesser hand they can’t lay down. The trap is usually sprung by the flop. Any pre-flop 2 or 3 gaped middle cards; like 9-6, 8-5, or small pairs that have hit a set or better.  Only call small bets, if you don’t hit the flop, don’t bet unless in position, must always be played cheaply, fold if not hit on the flop.
Against good players, large bets like 6xBB to 2x pot or more, from late position, when all else have folded, may be a trap with AA,KK, otherwise it’s someone trying to steal the blinds with a weak hand.

Pre-FlopHands

High pairs: (AA, KK, QQ): vary from call to big raise (3x-5x); re-raise 3x the raiser,  re-raise the re-raiser.
KK will flop an over card about 20% of the time, QQ about 33%, each successive lower card about 12% greater than the last.
(AA,KK) Can slow play a tight table or against loose players, but always re-raise the raiser at least 2 times their raise.
(QQ) vary your raises; call, do not re-raise unless heads-up only or the raise was small
Middle pairs: (JJ,TT): Raise 2x,3x, do not call or slow play; raise only, do not re-raise, unless heads-up. TT will see more action and likely to flop possible straight draws, due to being a KEY card.
Mid-Low Pairs: (99, 88, 77, 66): Raise 1x-2x, call small raises, do not re-raise. Likely to flop straight draws.
Low Pairs: (55, 44, 33, 22) Raise 1x-2x in early position, call in Middle to Late Position; Fold large raises.
There is a 10% chance Pairs will make a SET by the river make, 16% for 2 Pair, 1% for a Full House, and about .25% for 4 of a Kind.
AK,AQ,AJ (suited or un-suited): Raise 2x-3x, call small to medium raises, fold to large raises except for heads-up, then call. Good hands to raise in the blinds, but only 1x BB.
AT-A6 (suited): Call all small bets, raise in early position 1x, fold all large bets, except when heads up.
AT-A6 (un-suited): Call all small bets, don't raise or re-raise, fold all large bets, except when heads up. Try to see the flop cheaply. Call in early position, can call small raises if less than 3 other players.
A5-A2 (suited & un-suited); Call all small bets, fold 2x+ raises and large bets, except when heads up. Suited has more options than un-suited. Call suited cards in early position, fold if raised.

Move up a group if someone raises or bets 3x or more before you, unless you are heads-up

KQ-KJ-KT-QJ-QT (suited); bet 2x-3x in any position, call any small bet, check any normal bet or if more than 3 remaining players.
KQ-KJ-KT-QJ-QT (not suited); bet 2x-3x in early position, bet 1x-2x in middle or late position, call any small bet, check any normal bet or if more than 3 remaining players. Fold any large bet.
Any other 19+ hand: (suited), bet 1x-2x if everyone checks, call small bets, fold large bets. (Points)
Any other 19+ hand: (not suited); call small bets, check if possible, fold to large bets
Middle suited connectors: check if possible, bet in late position, call small bets in middle position, fold to large bets. Likely to flop flush and straight draws.
Middle non-suited connectors: check if possible, call small bets in late position, fold large bets. Likely to flop straight draws.
Low suited and non-suited connectors: check if possible, bet in late or middle position, fold any bet if more than 2 remaining players. Likely to be middle or low pair. Great trap hand if a set is made on the river.
Gapped suited cards: Try to keep the gaps to 2 or less. The higher the lead card the better, K-2 can be bet in late position, best to check only; Q-2 check only, fold any other, unless heads-up, then call only small bets. Cards with 1 gap are more likely to hit a flush than a straight. The chance of hitting a straight with 1 gap is the same as any suited connector.
Gapped non-suited cards: Try to keep the gaps to 2 or less. Cards with 1 gap have the same chance of hitting the flop for a straight as any non-suited connector.

Mental Exercise: Remember the last 3 flop textures. The probability is higher of a favorable flop hitting your hand if your hand is the opposite of the previous flops. (Gambler's Fallacy, but you will be surprised at how often it happens)

Lions and Tigers and Bears, OH MY!

Updated 2/11/2017

There are the 3 top cards in poker that prevail in anyone's 2 hold cards. 
Everyone plays Aces, Kings, and Queens, some with almost any other. 
The "Momma Bear or Queen" will be the most fierce card in the deck. Even Q7 or Q8 (unsuited) is a great hand to some players. To that extent, one of these 3 cards will hit the board about 50% of the time.
If you have one of them, you need to be aware of the ones you don't have, that end up hitting the board. If you don't have one, odds are better than 50%, someone does. Having 2 of them, AK, AQ, KQ, gives you the opportunity to gamble pre-flop. They are still just drawing cards, so don't go crazy, but most payers are not likely to throw them away pre-flop, regardless of the bets and raises.

Pre-Flop:
An Ace, King, or Queen will hit the flop about 50% of the time, so if it didn't show up, there's a good chance it will by the river. If you have the Queen and a good kicker and it hits the flop, you need to bet it to eliminate those who are waiting for their Ace or King to hit. The King is not so bad because you can usually chase it away, but people just love to hold on their Ace, especially if their other card already hit the flop.

After the flop:
Now we are down to betting into 4th street, or betting after the flop, so we are talking outs vs outs. You have one of the top 3 cards and are still in the hand because the betting has been low or everyone is just checking and waiting for their card. You have 3 outs or about 14% to hit your card vs 28% that one of the others will hit. 2 to 1 against you. If you are in the lead, you need to at least make a value bet, but that gives 3 to one odds, so you will likely be called. Bet the pot and give 2 to one, and you may also be called. You need to chase them away with about 1 and a half times the pot to 2 times the pot to put some pressure on them. If you have AK, AQ, KQ and one hits, your odds are reversed, but 3:1 odds are the minimum you are looking at. In order to play any of these, you need a deep stack or you are just gambling.

4th Street (Turn)
Betting into Fifth street, the odds are worse. 12:1 for you and only 6:1 for the others. Holding an Ace is optimal and preferred to holding the King or Queen. Even holding KQ and waiting for one to fall on the river is a big gamble, even with 8:1 odds to hit the King or Queen.

5th Street (the River)
You have what you have. Bet into weakness or check and determine what either of you have to lose.

The Power of Isolation

The objective of an isolation play is to make a wager big enough that it gets other players to fold, so you can be heads-up against one opponent. An isolation play can be used to isolate a tight player, bluffer, maniac, or a player on a draw. At loose tables, play tighter. At tight tables, play looser. Know who are the other players using the same tactic.

Whether it’s a tournament game or a ring game, Isolation is the key to building your stack. The object is to attempt to limit the field with your premium hands. Loose players use it to bluff or semi-bluff, some overuse it. Playing the isolation game is dependent on the ratio of BIG BLINDS to your stack size. You can limit the field with almost anything other than AA or KK, but always make at least a small bet when in position with AA or KK. Slow playing AA or KK can lead to big losses. The optimal situation is to have at least 100 Big Blinds. 
Arnold Snyder uses a Competitive Stack Factor of 60 big blinds as a minimum stack size to be competitive.

The first person to bet has the power. Position can change with each street, until heads up.

An A or K or Q will hit the flop 50% of the time or hit by the river 50% of the time. If you don't have one, someone does. You can almost estimate 10% for each player at the table, including yourself. With 8 players, it’s at least 80% that someone has an Ace, King, or Queen in their hand.

Pre-Flop: About Position: You are either IN or OUT!

STACK SIZES:

Less than 100BB: You must play small ball and be cautious with most of your playable hands, don't gamble.

IN POSITION:

Play long ball (raises and re-raises) only with your top 10 hands. Try to Isolate one player, but don’t try to push around the chip leader unless you have the nuts.

AA KK QQ must be raised if you are in position, and don’t be afraid to go all-in, do not slow play. Later you can use this to put others all-in when you think you have the best of it or the flop is "B" or less. (see Flop Ratings)

OUT OF POSITION:

Play small ball when you are out of position.

AA KK QQ can be played for a for a hit and run pre-flop, with a check raise or small bet followed by a re-raise if you are raised, regardless of the number of players in the hand.

Less than 50BB: You must play Tight Aggressive. Don’t gamble, but make the other players gamble. Take away their odds. Make it unprofitable to call your bet.

IN POSITION:

Play long ball (raises and re-raises) only with your top 5 hands.

OUT OF POSITION:

Play small ball when you are out of position.

More than 100BB: Be aggressive, but only in relation to the ratio of other stacks to your stack and position.

If you are the chip leader, you should only bet according to the ratio of stack sizes, not pot size.

IN POSITION:

Always keep the pressure on when you have a playable hand and you are in position.

Switch between small ball and long ball depending on who is in the hand and if you think you are ahead or not.

OUT OF POSITION:

Play according the the pot size until you think you have the best of it, then switch to playing for stacks.

Switch between making probe bets and value bets to disguise your hand. You should only be trying to disguise your hand if you are in the lead and intend to keep it.

Post Flop: About Position: You are either IN or OUT!

3^rd Street (the Flop):

The old saying of "if it doesn't fit the flop, FOLD!"
Get in or get out. Let the gamblers gamble. If your hand is not good enough to make an isolation play, keep it small and fold to any raises where there are more than two players still in the hand. The more players in the hand, the more likely you will be beat at the river, if you don't force them out.

4^th Street:

The Power of Position reverses at 4th Street (the Turn). You are usually heads-up or three handed at this point.

Power is relevant to the size of your stack (your “Q”) compared to everyone else.

5^th Street:

You have what you have. If you weren't betting the best hand or able to control a weak player, you are toast.

Poker outside the box.

Updated 2/11/2017

Poker pros are action freaks. The don't just play poker, they are so easily bored during the game that they have to play games within games. Side bets,  Proposition bets, insurance, running it twice, etc.

Double-flop Hold'em
An alternative to the traditional formats is, as the name suggests, to have two flops (and turns and rivers), now they call it "running it twice". In this game the pot is split between the winner according to each board, although it’s probable that someone somewhere has tried to play double flop hi-lo! The game can also be played with variations of hole card numbers and discards, which make things a lot more interesting. Two flops introduces key decisions like the choice between making an all-out attempt to win on one board (and perhaps scoop an opponent attempting to do the same) or trying to have some shot at both, or choosing between a combination of made hands and draws when you come to discard.

How does Insurance work?
Let's work with other numbers first just so I can be sure I'm doing all the math correctly. Let's say you're a 75% favorite. You win 75% of the time and lose 25% of the time, so you are a 75:25 favorite, or 3:1.

Let's make the insurance fully fair right now, so the rate will be 3:1 as well. We'll play for $10.

If you win the pot, which you will do often, you pay the $10. If you lose the pot, which you will do less often, you get paid 3 times that amount, or $30.

The way you can remember is that you pay the insurance the opposite of the pot -- win the pot, lose the insurance, but lose the pot and you win the insurance. If you're a favorite, you will win more than you lose, so you should pay the smaller amount when you win the pot. When you lose the pot in the rare situations, you then get a consolation prize that's bigger than what you would have paid. In other words, more frequent event involves less money and the less frequent event involves more money.

For 70%, it's 70:30, which is the same as 7:3, or (7/3):1, which is 2.33:1. It's just division. If you are giving insurance and are not in the pot, remember things are reversed from above. If the guy wins the pot, you get some of it. If he loses, you have to pay him. So, when you make money, it's the '1' in the ratio. When you pay out, it's the '2.33' in the ratio. To make it in your favor, just reduce your pay out, like give 2:1 odds.

Hold'em hi-lo
As you might imagine, in the search for different variations, hold’em games have often been played hi-lo as well. Crazy pineapple and Tahoe in particular allow for greater degrees of flexibility in going both ways. In the latter game A-A-2 is obviously the dream combination, although A-2-3 also allows for flexibility against being counterfeited for low. Since it is much harder to scoop by winning in both directions in variations of hold’em hi-lo which have a qualifier of 8 or better (i.e. the low hand must be five differently-valued cards of 8 or below), it is important to watch how the board develops. The board can make the difference between a chance to win everything or realizing you’re only playing for half and then playing accordingly.

Propositions for playing marginal hands like 72 and winning the pot outright or with a bluff. Propositions are bets outside the chips in the pot, something like an ante, but the money goes to the winner after the hand is done.
