value-bet

A value bet is a bet you make expecting the opponent to call with a weaker hand. Its +EV source is "the weaker hands in the opponent's range call and lose."

Detailed Explanation

The criterion for a value bet is simple:

Of the part of the opponent's range that will call, less than 50% beats your hand

If most of their calling range is weaker than you → value bet is +EV. If most of their calling range is stronger → this isn't a value bet, it's paying the opponent.

Core tradeoff of value-bet sizing:

• Large size: lower call frequency, but bigger win when called
• Small size: higher call frequency, smaller win when called
• Optimal sizing maximizes "call rate × amount won," typically 50-75% pot

Tiered by "value strength":

• Extreme value (nuts, top two pair+): can overbet or bet large
• Standard value (top pair good kicker, overpair): standard 50-66% value bet
• Thin value (middle pair vs weak range): small size (25-40%) — get bottom pair / A-high to call

Under range thinking, value-betting requires reading the opponent's call range, not just looking at your own hand strength. The same KQ on a K72r flop is standard value vs a tight-passive opponent and thin value vs a very loose one.

Common Use Cases

• River: the purest stage for value betting — opponent's range is narrowed and call frequencies are precisely estimable
• Three-street value: top two pair+ on dry boards is value across all three streets
• Thin river value: middle pair often still ahead of the opponent's check-call range — small-size for extra value
