Bluff catching is a poker strategy where a player with a marginal hand tries to catch an opponent who is bluffing. This involves calling a bet on the river with a hand that is not particularly strong but has some potential to win the pot. The goal is to catch an opponent who is trying to steal the pot by making a bet with a weaker hand, or to induce them to bluff again in a later hand. Bluff catching requires a good read on the opponent’s betting patterns and the ability to make a well-timed call. It is a high-risk, high-reward strategy that can result in a big win or a big loss depending on the outcome of the hand.
