I'll show you a basic approach. Showdown EV for a bet by you is EV = F*P +(1-F)(E*(P+2B)-B) where F = fold equity (probability villain folds) P = pot before your bet B = your bet You can set EV to 0 and solve for F, or you can write the equation in Excel and use its Goal Seek function to find the F that gives an EV of 0. If you set EVcall = E*(P+2B)-B, then the break-even F is F' = EVcall/(EVcall-P), If F' is negative, you have +EV no matter what. Note that if E = 0, i.e., you are on a total bluff, then F' = B/(P+B), a well known result. If it is not an all-in situation, then you can add implied odds to the profit part of the EVcall factor for a first cut approach to a much more complex situation
