Postflop calls

Calling or folding after the flop when the price is exact: facing an all-in, or a bet on the river.

What it means
Some postflop decisions need no solver. When the villain is all-in, or it is the river, no more betting can follow, so the call is right exactly when your equity beats the equity you need.
How it is calculated
Your equity against the villain's range comes from the engine, which enumerates or samples every runout. The equity you need is the call ÷ the final pot. Call when equity is higher, fold when it is lower.
Worked example
On the river the pot is 20bb and the villain bets 10bb. You call 10bb to win a 40bb final pot, so you need 25%. Against a range that bets many bluffs your bluff-catcher has 32%, so the call earns 0.32 × 40 − 10 = 2.8bb.
Why it matters
Earlier in a hand, implied odds and later bets blur the math. These spots are the pure form of pot odds against a range.
