Facing a two-thirds-pot bet on the flop with 19 outs, the call is correct: 65.03% to hit against 28.57% needed. - Verdict: Call (19 outs, flop, two-thirds-pot bet) - Chance to hit by the river: 65.03% (two cards to come) - Equity the call needs: 28.57% ($66.67 into a pot of $233.33) - Margin over the price: +36.46 points (your chance minus the price) ## The price of the call Your draw is priced at 28.57% and it arrives 65.03% of the time. A lead of 36.46 points is wide enough that the call stands even if the numbers shift a little. A count of 19 outs is usually the sum of more than one draw. Out of 47 unseen cards, one card helps 40.43% of the time. ## The $100 pot example - Pot when the bet arrives: $100 - Your opponent bets: $66.67 - You call: $66.67 - Pot with your call in: $233.33 - What a hit wins: $166.67 - Net loss when you miss: $66.67 - Chance to hit by the river: 65.03% - Calling is worth, on average: +$85.08 - Equity needed to break even: 28.57% - Margin, to four decimals: +36.4609 points - Outs that exactly reach the price: 7.20 outs - Outs to spare, exactly: +11.80 outs Stay with simple rules: the whole pot on a hit, the call lost on a miss, no more money in. Under them calling gains $85.08 on average. The hit side averages $108.39, the miss side $23.31, and each dollar called returns +1.276. The same comparison in odds: the odds against hitting are 0.54 : 1, and the pot lays 2.5 : 1 on a call. Skipping your own call in the pot gives a price of 40.00% where 28.57% is correct, and a margin of +25.0324 points instead of +36.46 points. The starting pot gives 66.67% and a margin of -1.6343 points, which is wrong by even more. ## What could go wrong before the call flips Count how many outs the call needs: 8 reach the 28.57% price, and you have 19. That leaves 11 outs of slack.

The answer is a call, with a margin of +36.46 points. 19 outs on the flop reach 65.03%; a bet of $66.67 into $100 needs 28.57%. Win the whole pot on a hit and lose the call on a miss, and the call is worth +$85.08 on average. ### How many outs make a call correct against two thirds of the pot on the flop? 8 outs is the line. At 8 the chance is 31.45%, enough for 28.57%; one fewer gives 27.84%, which is not. Your 19 outs sit 11 above it on the flop, at 65.03%. ### One card or two: which number belongs next to the 28.57% price? Count two cards, 65.03%, when the bet is the last money going in, and one card, 40.43%, when the next street brings another bet. At a price of 28.57%, either number leads to a call. ## How this is computed Counting is exact: the pairs of unseen cards with no out number 378 out of 1,081, so hitting by the river has chance 65.03%. Read the verdict with its limits in mind. The call is the full bet, so the break-even equity is $66.67 / $233.33 = 28.57%. 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.
