Bluffing in poker can often be detected through various behavioral and game-related cues. A player might act inconsistently with the strength of their hand, such as making unusually large bets or raises despite having weak cards. They may show signs of nervousness or hesitation, such as fidgeting, talking too much, or looking overly confident. Conversely, they might try to appear calm or disinterested while secretly holding a strong hand. In terms of gameplay, bluffers may avoid betting or acting aggressively when they actually have a strong hand, and they may suddenly switch strategies to create uncertainty. Observing how their actions differ from previous patterns can be a key indicator of bluffing.
