Protection Bet: Making the Draws Pay for the Next Card
A protection bet is a bet with a hand that is ahead but can be outdrawn, so that the hands drawing against it pay to see the next card. Checking gives them that card for free. The bet does not make a draw fold by itself; it puts a price on the next card, and the draw decides whether that price is worth paying.
Check a made hand against a draw
Enter A♠J♣ against K♥Q♥ on A♦ 9♥ 4♥, then add a turn card:
A♠J♣ on A♦ 9♥ 4♥
A♠J♣ against hands that can call on this flop, with the turn and river to come:
| Opponent's hand | What it holds | A♠J♣'s equity |
|---|---|---|
| K♥Q♥ | flush draw | 62.8% |
| 8♥7♥ | flush draw | 61% |
| T♣9♣ | second pair | 81.6% |
| 6♠5♠ | no pair, no draw | 93.6% |
After a 2♣ turn, A♠J♣ goes up to 79.5% against K♥Q♥: one card fewer for the flush. With both hands known, the flush draw has 9 outs among 45 unseen cards, so it hits on the next card 20% of the time.
What each bet charges the flush draw
| Your bet | Equity the draw needs to call |
|---|---|
| 33% of the pot | 19.9% |
| 50% of the pot | 25% |
| 75% of the pot | 30% |
| the pot | 33.3% |
A bet of a third of the pot asks for about as much as the draw's 20% on the next card; half the pot or more asks for more. A check asks for nothing.
