Poker bluffing
A poker bluff is a bet or raise made when you believe your hand is not the best, intended to make opponents fold stronger hands.
- Also called
- Pure bluff or stone-cold bluff when the hand has little chance of improving1
- Game-theory rule
- David Sklansky's rule: bluff a percentage equal to the opponent's pot odds; e.g. with 2-to-1 pot odds, bluff one out of three times3
- Semi-bluff
- A bluff with some chance to improve the hand later2
Key points
- A bluff succeeds when the expected folds from opponents outweigh the cost of the bet1.
- The player represents strength through betting action while holding a weak hand, hoping opponents interpret the bet as credible and fold14.
- A semi-bluff is a bet with a weak hand that still has a chance to improve on later cards2.
How to tell a bluff in poker
- Watch for betting patterns: a sudden large bet on a weak board may signal a bluff, while a consistent pattern of small bets often indicates strength.
- Look for physical tells like shaking hands, avoiding eye contact, or forced calmness, though these vary by player.
- Consider opponent tendencies: tight players bluff less often, while aggressive players bluff more frequently.
- Analyse board texture: a bluff is more likely on a coordinated board that could have completed a draw, as the bettor may be representing a hand they don't have.

How to tell a bluff in poker?
Look for betting pattern changes, such as a sudden large bet on a board that doesn't favour strong hands. Watch for physical tells like nervousness or forced calmness. Consider the opponent's typical style: tight players bluff less, aggressive players bluff more. Also note board texture — a bluff is more likely when the board could have completed a draw.
