By the numbers it is a call. 17 outs on the flop hit 59.76% by the river, a two-thirds-pot bet needs 28.57%, and the margin is +31.19 points. That assumes you call the full $66.67 and no more betting follows, and it values the call at +$72.77 per $100 pot. ### How strong must a draw be to call a two-thirds-pot bet on the flop? You need at least 8 outs against a two-thirds-pot bet on the flop. That count hits 31.45% against 28.57% needed, and 7 falls short at 27.84%. With 17 you are 9 past 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 28.57%, and the verdict is call either way. ## How this is computed Here is how 59.76% was found. Deal every pair of the 47 unseen cards: 435 of 1,081 pairs contain no out. What is held fixed: the call equals the bet, so the price is $66.67 / $233.33 = 28.57%; the pot is won whole on a hit; there is no further betting; and each of the 47 unseen cards is as likely as any other. Opponent cards are not removed.
