What it means

For a pure bluff risking B to win P, required folds are B divided by P plus B.

AT THE TABLE

A practical example

A 50 bet into a 100 pot needs folds more than one-third of the time to profit as a pure bluff.

The calculation

Pure-bluff break-even fold rate = bet ÷ (pot before your bet + bet).

The example above shows the idea with stated assumptions. Actual decisions also depend on ranges, future action, and the game format.

Where you will hear it
