USS Cairo was a City-class ironclad gunboat constructed for the Union Navy by James Buchanan Eads during the American Civil War, 1861, was named for Cairo, Illinois.
There is nothing Ironclad in playing poker.
That being said, there is no Sportsmanship in Poker, same thing with Hockey, but that another story. Unlike Hockey, Poker players are not supposed to cheat and slow playing is not cheating. It's what some players do to build the pot because they think they are invincible with hands like AA.
Slow playing will lose you money.
Here's my RULE or axiom:
If you can be beat at the river, you will be beat at the river, when it will lose you the most money.
If you have a hand like AA, KK, or QQ, you can slow play before the flop if you are the first to act and you have normally aggressive players after you, with AA, KK you should raise any bet they make at least 2x to 3x their bet, call with QQ; otherwise always play aggressive from start to finish.
About Slow Playing
Slow playing (also called sandbagging or trapping) is deceptive play in poker that is roughly the opposite of bluffing: betting weakly or passively with a strong holding rather than betting aggressively with a weak one. The flat call is one such play. The objective of the passive slow play is to lure opponents into a pot who might fold to a raise, or to cause them to bet more strongly than they would if the player had played aggressively (bet or raised). Slow playing sacrifices protection against hands that may improve and risks losing the pot-building value of a bet if the opponent also checks.
- A player must have a very strong hand.
- The free card or cheap card the player is allowing to his opponents must have good possibilities of making them a second-best hand.
- That same free card must have little chance of giving an opponent a better hand or even giving them a draw to a better hand on the next round with sufficient pot odds to justify a call.
- The player must believe that he will drive out opponents by showing aggression, but can win a big pot if the opponents stay in the pot.
- The pot must not yet be very large.
