探查式诈唬（Probe Bluff）

Probe Bluff is a common poker strategy, primarily used on the flop or turn. Its core principle: when the previous round's bettor checks in the current round, it indicates their hand may be weak or missed the board, allowing a later-position player to bet—potentially winning the pot outright while also gathering information.

Applicable Scenarios

• Preflop aggressor checks: When the preflop raiser checks on the flop, it usually means they missed the flop. In this case, the last player to act can bet with a wider range, especially when the flop structure favors them.
• Turn check: When the flop bettor checks on the turn, it may indicate they failed to improve on the turn or are giving up on a bluff. A later-position player can then attempt to steal the pot.

Advantages and Risks

• Advantages: Probe bluffs can win the pot at a low cost and force opponents to reveal their hand strength. If the opponent calls, the bettor can slow down; if the opponent folds, they profit immediately.
• Risks: Opponents may trap with strong hands (check-raise), especially on wet boards or when the opponent has a range advantage. Overuse can also erode credibility.

Difference from Continuation Bet

A continuation bet (C-bet) is an active bet by the preflop aggressor on the flop, whereas a probe bluff occurs after the preflop aggressor has checked. The latter is typically initiated by a later-position player and does not require preflop initiative.

Example

Preflop, Player A raises, Player B calls. On the flop, A checks. B holds a completely unrelated hand but judges that A likely missed, so B bets as a bluff. If A folds, B successfully steals the pot; if A calls, B may give up on later streets.
