Compare 62.44%, your chance to hit by the river, with 30.00%, the equity a three-quarter-pot bet needs. The gap is +32.44 points, so this is a call. In dollars on a $100 pot, the call averages +$81.11 when no more betting follows. ### At what count of outs does a three-quarter-pot bet on the flop become a call? The threshold is 8 outs. It gives 31.45%, clearing 30.00%, whereas 7 gives only 27.84%. Holding 18 puts you 10 above it, with a chance of 62.44%. ### How many cards should you count when a three-quarter-pot bet arrives on the flop? Match the number to the betting: 62.44% if all-in or checked down, 38.30% if you face another bet on the turn. The price is 30.00%, and both numbers agree on call. ## How this is computed Here is how 62.44% was found. Deal every pair of the 47 unseen cards: 406 of 1,081 pairs contain no out. The numbers are a baseline rather than a prediction for one hand. The price is 30.00%, from $75 into $250, 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.
