Call when your equity beats 22.22%. The figure is your $40 call divided by the $180 pot you play for, and it equals pot odds of 3.5 : 1. Use it on every street where a two-fifths-pot bet shows up. ### How many outs do you need against a two-fifths-pot bet? Against a bet of two fifths of the pot, the fewest outs that reach 22.22% on the flop is 6, with 24.14% to hit by the river. On the turn you need 11 outs. Always check that your outs are clean before relying on the count. ### How much do implied odds help against a two-fifths-pot bet? Plenty, if the money is real. At $50 of future winnings the price is 17.39%, and at $500 it is 5.88%, compared with 22.22% with none. Be realistic about what your opponent will pay. ### Can you call a two-fifths-pot bet with a flush draw? Start with the count of 9 outs. On the flop its chance to hit by the river is 34.97%, which is above 22.22%, so it is a call. On the turn the chance is 19.57%, which is below 22.22%, so it is a fold. A bet of two fifths of the pot sets the line at 22.22% in both cases. ## How this is computed This page works out the equity a call needs when a $100 pot faces a bet of two fifths of the pot, and it compares that price with the chance to hit common draws on the flop and on the turn. Using f = 0.4, the formula e = f / (1 + 2f) returns 22.22%. The odds form is (1 + f) / f, which returns 3.5 : 1. The two are the same price written two ways. Three assumptions sit under every number: you call the whole bet, nobody bets again, and a hit wins the pot outright. Each of the 47 unseen cards on the flop, or 46 on the turn, is equally likely. Method: the closed form f / (1 + 2f) computed by the GeorgeLiPoker math library, with draw chances counted from the unseen cards. ## Related pages - [Pot odds calculator](https://georgelipoker.com/tools/pot-odds-calculator.md) - [Outs calculator](https://georgelipoker.com/tools/outs-calculator.md) - [Pot odds by bet size](https://georgelipoker.com/pot-odds.md) - [Facing a third-pot bet](https://georgelipoker.com/pot-odds/third-pot.md) - [Facing a half-pot bet](https://georgelipoker.com/pot-odds/half-pot.md) - [Hand against hand equity](https://georgelipoker.com/equity.md) ## Related - [Pot Odds by Bet Size](https://georgelipoker.com/pot-odds.md)
