What are the pot odds on an overbet?

One-card direct odds assume you fold after a miss and pay no further bets. Use by-the-river odds when this call guarantees both cards, such as an all-in or a guaranteed free river.

Overbets exist to deny draws their price. At 1.5 times the pot you need nearly 38% to call, which most single draws cannot meet on direct odds. That is the point: an overbet forces draws to fold or pay an overpriced toll.

Worked example: the pot is 100 on the turn and your opponent bets 150. You call 150 to win the 100 already there plus the 150 bet, 250 in total. 150 to win 250 is 1.7-to-1, and 150 divided by 400, the pot after your call, is 37.5%.

No single common draw reaches 37.5% on the next card: a flush draw is 19.1%, an open-ender 17.0%, even a combo draw 31.9%. Only a combo draw that is all-in on the flop, at 54.1%, clears it. The overbet also works against made hands, because a one-pair hand facing 1.5 times the pot has to be right well over a third of the time, and against a range of strong value hands and bluffs that is a hard call to make.

Quick tip: Overbets blow past the price of a draw: 1.5x pot needs about 38% equity.
