On the turn, 17 outs are enough to call a half-pot bet. The price is 25.00% and the chance is 36.96%. - Verdict: Call (17 outs, turn, half-pot bet) - Chance to hit by the river: 36.96% (one card to come) - Equity the call needs: 25.00% ($50 into a pot of $200) - Margin over the price: +11.96 points (your chance minus the price) ## The price of the call The price is 25.00% and your chance is 36.96%. You sit 11.96 points above the line, which is a wide gap, so you call. Think of 17 outs as a running total of every card that improves you. 17 of the 46 unseen cards qualify, which is 36.96% on one card. ## Worked through on a $100 pot - Pot before the bet: $100 - Bet: $50 - Cost to call: $50 - Final pot if you call: $200 - What a hit wins: $150 - What a miss costs: $50 - Chance to hit by the river: 36.96% - Calling is worth, on average: +$23.91 - Break-even equity: 25.00% - Your chance minus the price, unrounded: +11.9565 points - Outs at break-even: 11.50 outs - Outs to spare, exactly: +5.50 outs Over many identical spots, with the whole pot won on every hit, the call lost on every miss and no extra betting, calling gains $23.91 on average. Hits bring in $55.43, misses cost $31.52, and the ratio is +0.478 per dollar called. Read as odds: 1.71 : 1 against you, 3 : 1 from the pot. A common slip is to divide the bet by the pot after the bet but before your call. That gives 33.33% instead of 25.00% and would put your margin at +3.6232 points. Using the bet over the starting pot, 50.00%, is further off and would put it at -13.0435 points. ## Reverse implied odds and your margin If some outs turned out to be shared with a better hand, you could give up 5 outs and still call. The floor is 12, at 26.09%.

Verdict: call. A half-pot bet asks for 25.00% and you have 36.96%, a margin of +11.96 points. For a $50 call into a $100 pot, with no later bets and the whole pot won on a hit, the average is +$23.91. ### What count of outs clears the price of a half-pot bet on the turn? The threshold is 12 outs. It gives 26.09%, clearing 25.00%, whereas 11 gives only 23.91%. Holding 17 puts you 5 above it, with a chance of 36.96%. ### Should you use the chance on the next card or by the river? They are one number here. With a single card to come, 36.96% is both the next-card chance and the by-the-river chance, and it gives a call against 25.00%, a margin of +11.96 points. ## How this is computed The hit chance comes straight from combinations. With one card left and 17 outs in 46 cards, you hit 36.96% of the time. 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 46 unseen cards is equally likely. The price is $50 / $200 = 25.00%. No card is taken out for what an opponent might hold.
