Key points

  • Effectiveness depends on opponents believing the threat of a stronger hand and folding accordingly13.
  • Bluffing may also be used to disguise play patterns2.

Poker bluff example

You hold 7♣ 2♦ on a flop of A♠ K♦ 3♥. You have no pair, no draw. You bet as if you held a strong ace. If your opponents fold, you win the pot without the best hand. This is a pure bluff.

How to bluff in poker

  1. Choose a situation where your hand is weak but the board suggests you could have a strong hand.
  2. Bet or raise with confidence, as if you hold that strong hand.
  3. Watch your opponents: if they fold, you win. If they call or raise, you may need to give up the bluff.
