Chance 34.97%, price 33.33%, so call. A pot-size bet on the flop is worth calling with 9 outs. You hit 34.97% of the time by the river and the call needs 33.33%. - Verdict: Call (9 outs, flop, pot-size bet) - Chance to hit by the river: 34.97% (two cards to come) - Equity the call needs: 33.33% ($100 into a pot of $300) - Margin over the price: +1.63 points (your chance minus the price) ## What the numbers say The call just clears the price. You hold 34.97%, the pot-size bet asks for 33.33%, and the margin is 1.63 points. Holding a flush draw gives you exactly 9 outs, out of 47 unseen cards. One card hits 19.15% of the time. ## Worked through on a $100 pot - Pot when the bet arrives: $100 - Bet: $100 - You call: $100 - Final pot if you call: $300 - Gain on a hit: $200 - You lose on a miss: $100 - Your chance to hit: 34.97% - Expected value of calling: +$4.90 - Equity the call needs: 33.33% - Your chance minus the price, unrounded: +1.6343 points - Outs that exactly reach the price: 8.53 outs - Your outs minus break-even outs: +0.47 outs If you win the whole pot on a hit and lose your call otherwise, with no more betting, calling gains $4.90 on average. Hits add $69.94 on average and misses cost $65.03 on average, or +0.049 per dollar called. Odds say the same thing. Hitting is 1.86 : 1 against, and the pot lays 2 : 1. Do not forget your own call. Dividing the bet by the pot without it gives 50.00%, not 33.33%, and would show a margin of -15.0324 points. ## How much room the call has The call does not survive losing even one out. At 9 outs the chance is 34.97%, just enough for 33.33%, and that is the count you hold. Price of a pot-size call if you give money back after a hit, 9 outs on the flop | Given back later | Price with it | Your chance minus price | Value of the call | Call? | | --- | --- | --- | --- | --- | | $0 | 33.33% | +1.63 points | +$4.90 | Call | | $10 | 34.48% | +0.48 points | +$1.41 | Call | | $25 | 36.36% | -1.40 points | -$3.84 | Fold | | $50 | 40.00% | -5.03 points | -$12.58 | Fold | | $100 | 50.00% | -15.03 points | -$30.06 | Fold | Reverse implied odds are the risk here. A hit that costs you $14.02 later, 0.14 times your call, is where the call stops being worth it. ## Next card or river 9 outs against a pot-size bet, one view per row | Cards counted | Chance | Margin over price | Value of the call | Verdict | | --- | --- | --- | --- | --- | | By the river, two cards | 34.97% | +1.6343 points | +$4.90 | Call | | Next card only | 19.15% | -14.1844 points | -$42.55 | Fold | Watch the difference between one card and two. By the river you hold 34.97%, a call; on the next card alone you hold 19.15%, a fold. A bet on the turn tips you toward the smaller number. ## A few outs either way Here are the neighbors of 9 outs, priced against the same 33.33%. One more out lifts your chance by about 3.42 points.

Math says call. The pot-size bet of $100 needs 33.33% equity, 9 outs on the flop give 34.97%, and the margin is +1.63 points. Assuming a whole pot won on a hit and no further bets, the call is worth +$4.90 on average. ### What count of outs clears the price of a pot-size bet on the flop? To call a pot-size bet on the flop you want 9 outs or more. 9 reach 34.97% and 8 reach 31.45%, with 33.33% as the bar. Your 9 outs are right on the line. ### Is the by-the-river chance the right one to use on the flop? Pick the number that matches the street plan: 34.97% for seeing both cards for one bet, 19.15% for paying card by card. Both face 33.33%, and they lead to call and fold in that order. ## How this is computed The chance to hit is the exact closed form, with no simulation. From the flop, 703 of the 1,081 possible pairs of unseen cards hold no out, so the chance is 1 minus 703 / 1,081, which is 34.97%. Read the verdict with its limits in mind. The call is the full bet, so the break-even equity is $100 / $300 = 33.33%. A hit takes the whole pot, no later betting happens, and the 47 unseen cards are all equally likely, with none removed for an opponent's cards. Computed from the closed form by the GeorgeLiPoker math library. ## Related pages - [9 outs on the flop](https://georgelipoker.com/outs/9-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)
