Call. With 19 outs on the flop, your 65.03% chance beats the 20.00% price of a third-pot bet. - Verdict: Call (19 outs, flop, third-pot bet) - Chance to hit by the river: 65.03% (two cards to come) - Equity the call needs: 20.00% ($33.33 into a pot of $166.67) - Margin over the price: +45.03 points (your chance minus the price) ## Chance against price Your draw is priced at 20.00% and it arrives 65.03% of the time. A lead of 45.03 points is wide enough that the call stands even if the numbers shift a little. No single everyday draw has exactly 19 outs, so a count like this usually combines draws. One card from the 47 unseen helps 40.43% of the time. ## Worked through on a $100 pot - Pot when the bet arrives: $100 - Size of the bet: $33.33 - Your call: $33.33 - Pot after your call: $166.67 - You can win on a hit: $133.33 - You lose on a miss: $33.33 - Probability of a hit: 65.03% - Expected value of a call: +$75.05 - Price of the call: 20.00% - Your chance minus the price, unrounded: +45.0324 points - Break-even count of outs: 4.91 outs - Outs above the price: +14.09 outs Expected value says the same in dollars. Win the whole pot on a hit, lose your call on a miss, add no more betting, and the call gains $75.05 on average: $86.71 in, $11.66 out, +2.252 per dollar called. Odds say the same thing. Hitting is 0.54 : 1 against, and the pot lays 4 : 1. Skipping your own call in the pot gives a price of 25.00% where 20.00% is correct, and a margin of +40.0324 points instead of +45.03 points. The starting pot gives 33.33% and a margin of +31.6990 points, which is wrong by even more. ## Reverse implied odds and your margin The call survives losing up to 14 outs. At 5 outs the chance is 20.35%, just enough for 20.00%.

By the numbers it is a call. 19 outs on the flop hit 65.03% by the river, a third-pot bet needs 20.00%, and the margin is +45.03 points. That assumes you call the full $33.33 and no more betting follows, and it values the call at +$75.05 per $100 pot. ### How many outs make a call correct against a third of the pot on the flop? The threshold is 5 outs. It gives 20.35%, clearing 20.00%, whereas 4 gives only 16.47%. Holding 19 puts you 14 above it, with a chance of 65.03%. ### Which chance should you compare with the price, the next card or the river? 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 20.00%, 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%. Four assumptions sit behind the verdict: you call the full bet, a hit wins the entire pot, no money goes in after the call, and every one of the 47 unseen cards is equally likely. The price is $33.33 / $166.67 = 20.00%. No card is taken out for what an opponent might hold.
