Bet Sizing

Bet sizing refers to the amount wagered relative to the pot (e.g., 33%, 50%, 100%, 150%). Solvers have revolutionized understanding of sizing: small sizes (25-33%) should be used with high frequency and linear ranges, while large sizes (75%+) should be used with low frequency and polarized ranges. Using multiple sizes in the same spot (multi-sizing) is a hallmark of advanced solver strategy.

Example

Solver output: With a strong hand on the turn, bet 75% pot 60% of the time and 33% pot 40% of the time (multi-sizing).
