The math says call." related: ["https://georgelipoker.com/call-or-fold.md"] --- # Call or Fold: 13 Outs vs 3/4 pot, Flop With 13 outs on the flop you hit 48.10%; a three-quarter-pot bet needs 30.00%. The math says call. Here is why a call works on the flop: a three-quarter-pot bet needs 30.00% equity, and 13 outs supply 48.10%. - Verdict: Call (13 outs, flop, three-quarter-pot bet) - Chance to hit by the river: 48.10% (two cards to come) - Equity the call needs: 30.00% ($75 into a pot of $250) - Margin over the price: +18.10 points (your chance minus the price) ## Chance against price 48.10% against 30.00%: the draw beats the price by 18.10 points. On this flop against a three-quarter-pot bet, that is a comfortable call. Think of 13 outs as a running total of every card that improves you. 13 of the 47 unseen cards qualify, which is 27.66% on one card. ## Putting dollars on the call - Starting pot: $100 - Your opponent bets: $75 - Your call: $75 - Final pot if you call: $250 - Gain on a hit: $175 - Loss on a miss: $75 - Your chance to hit: 48.10% - Average value of the call: +$45.26 - Equity needed to break even: 30.00% - Your chance minus the price, unrounded: +18.1036 points - Outs that exactly reach the price: 7.59 outs - Outs to spare, exactly: +5.41 outs If you win the whole pot on a hit and lose your call otherwise, with no more betting, calling gains $45.26 on average. Hits add $84.18 on average and misses cost $38.92 on average, or +0.603 per dollar called. The same comparison in odds: the odds against hitting are 1.08 : 1, and the pot lays 2.33 : 1 on a call. One easy error is to use 42.86%, the bet over the pot before your call, as the price. The right price is 30.00%, and the mistaken margin would be +5.2465 points. The bet over the starting pot, 75.00%, would claim -26.8964 points. ## Slack in the call Against this bet the draw needs 8 outs at the least. You have 5 outs more than that, so the call has some room.

Your chance, 48.10%, set against the 30.00% price gives +18.10 points and a call. With a $100 pot, a $75 call and no more betting, the average value of the call is +$45.26. ### What is the fewest outs that can call a three-quarter-pot bet on the flop? A call starts to work at 8 outs: 31.45% to hit versus 30.00% needed. One out fewer drops the chance to 27.84%. You hold 13, which is 5 more than the minimum. ### Which chance should you compare with the price, the next card or the river? Pick the number that matches the street plan: 48.10% for seeing both cards for one bet, 27.66% for paying card by card. Both face 30.00%, and they lead to call and fold in that order. ## How this is computed The number is exact rather than estimated. 561 of the 1,081 pairs that could come are blanks, which leaves 48.10% for a hit. What is held fixed: the call equals the bet, so the price is $75 / $250 = 30.00%; 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.
