Your draw is priced fairly enough to call here: 59.76% to hit, 25.00% needed against a half-pot bet on the flop. - Verdict: Call (17 outs, flop, half-pot bet) - Chance to hit by the river: 59.76% (two cards to come) - Equity the call needs: 25.00% ($50 into a pot of $200) - Margin over the price: +34.76 points (your chance minus the price) ## Reading the verdict The price is 25.00% and your chance is 59.76%. You sit 34.76 points above the line, which is a wide gap, so you call. Few single draws land on exactly 17 outs, so add up each way to improve and check the total. One card hits 36.17% of the time here. ## The $100 pot example - Pot before the bet: $100 - Bet: $50 - Your call: $50 - Pot after your call: $200 - You can win on a hit: $150 - Loss on a miss: $50 - How often you hit: 59.76% - Average value of the call: +$69.52 - Equity the call needs: 25.00% - Margin, to four decimals: +34.7595 points - Break-even count of outs: 6.23 outs - Margin measured in outs: +10.77 outs Suppose a hit wins the entire pot, a miss loses your call, and no more betting follows. The average gain is $89.64, the average loss is $20.12, and calling gains $69.52 on average, or +1.390 per dollar called. Put as odds, the draw is 0.67 : 1 against, and the pot offers 3 : 1 for the call. Do not forget your own call. Dividing the bet by the pot without it gives 33.33%, not 25.00%, and would show a margin of +26.4261 points. The bet over the starting pot, 50.00%, is worse and would show +9.7595 points. ## How much room the call has Against this bet the draw needs 7 outs at the least. You have 10 outs more than that, so the call has some room.

Compare 59.76%, your chance to hit by the river, with 25.00%, the equity a half-pot bet needs. The gap is +34.76 points, so this is a call. In dollars on a $100 pot, the call averages +$69.52 when no more betting follows. ### How many outs do you need to call a half-pot bet on the flop? To call a half-pot bet on the flop you want 7 outs or more. 7 reach 27.84% and 6 reach 24.14%, with 25.00% as the bar. Your 17 outs are 10 over. ### When is the next-card chance the better comparison? Match the number to the betting: 59.76% if all-in or checked down, 36.17% if you face another bet on the turn. The price is 25.00%, and both numbers agree on call. ## How this is computed Everything is computed from the closed form. Pairs without an out: 435 of 1,081. The rest, 59.76%, hold at least one out. The numbers are a baseline rather than a prediction for one hand. The price is 25.00%, from $50 into $200, and the chance assumes a whole pot won on a hit, no more betting, 47 equally likely unseen cards, and no cards removed for the other player. Computed from the closed form by the GeorgeLiPoker math library. ## Related pages - [17 outs on the flop](https://georgelipoker.com/outs/17-outs-flop.md) - [Pot odds for a half-pot bet](https://georgelipoker.com/pot-odds/half-pot.md) - [Pot odds calculator](https://georgelipoker.com/tools/pot-odds-calculator.md) - [Outs calculator](https://georgelipoker.com/tools/outs-calculator.md) - [Call or fold with a draw](https://georgelipoker.com/call-or-fold.md) ## Related - [Call or Fold With a Draw by Bet Size](https://georgelipoker.com/call-or-fold.md)
