The math says call." related: ["https://georgelipoker.com/call-or-fold.md"] --- # Call or Fold: 17 Outs vs full pot, Flop With 17 outs on the flop you hit 59.76%; a pot-size bet needs 33.33%. The math says call. Call. With 17 outs on the flop, your 59.76% chance beats the 33.33% price of a pot-size bet. - Verdict: Call (17 outs, flop, pot-size bet) - Chance to hit by the river: 59.76% (two cards to come) - Equity the call needs: 33.33% ($100 into a pot of $300) - Margin over the price: +26.43 points (your chance minus the price) ## What the numbers say Pay the pot-size bet and you get a better deal than the draw needs. You need 33.33%, you have 59.76%, and the 26.43-point difference is large. You will reach 17 outs by adding up separate draws. With 47 cards unseen, the next card helps 36.17% of the time. ## One hand, in dollars - Starting pot: $100 - The bet: $100 - Chips you put in: $100 - Final pot if you call: $300 - You can win on a hit: $200 - Loss on a miss: $100 - Chance to hit by the river: 59.76% - Average value of the call: +$79.28 - Equity needed to break even: 33.33% - Margin, to four decimals: +26.4261 points - Fractional outs at the price: 8.53 outs - Margin measured in outs: +8.47 outs If you win the whole pot on a hit and lose your call otherwise, with no more betting, calling gains $79.28 on average. Hits add $119.52 on average and misses cost $40.24 on average, or +0.793 per dollar called. As odds, 0.67 : 1 against hitting meets pot odds of 2 : 1. Skipping your own call in the pot gives a price of 50.00% where 33.33% is correct, and a margin of +9.7595 points instead of +26.43 points. ## Slack in the call 9 outs is the line for a pot-size bet on the flop. Your 17 sit 8 outs above it, and the chance at the line is 34.97%.

Math says call. The pot-size bet of $100 needs 33.33% equity, 17 outs on the flop give 59.76%, and the margin is +26.43 points. Assuming a whole pot won on a hit and no further bets, the call is worth +$79.28 on average. ### How strong must a draw be to call a pot-size bet on the flop? A call starts to work at 9 outs: 34.97% to hit versus 33.33% needed. One out fewer drops the chance to 31.45%. You hold 17, which is 8 more than the minimum. ### Should you use the chance on the next card or by the river? Pick the number that matches the street plan: 59.76% for seeing both cards for one bet, 36.17% for paying card by card. Both face 33.33%, and the verdict is call either way. ## How this is computed The chance to hit is the exact closed form, with no simulation. From the flop, 435 of the 1,081 possible pairs of unseen cards hold no out, so the chance is 1 minus 435 / 1,081, which is 59.76%. The price is call / (pot + bet + call), here $100 / $300 = 33.33%, and the margin is your chance minus it. The page assumes you call the whole bet, win the whole pot whenever you hit, and see no more betting. All 47 unseen cards are equally likely and none is removed for an opponent's hand, so this is the chance to hit your outs, not your equity against one hand. 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 pot-size bet](https://georgelipoker.com/pot-odds/pot-size.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)
