overbet

An overbet is a bet larger than the current pot, commonly used on the turn or river. It's a regular tool at high-stakes cash and late tournament play.

Detailed Explanation

An overbet range must be extremely polarized: top-end value (nuts or near-nuts) or selected bluffs. Medium-strength hands should not be in the overbet range.

What makes overbets effective:

1. Maximizing value: when the opponent calls with a strong made hand, you win far more than at standard sizing
2. Maximizing fold equity: a huge size forces opponents to give up most of their bluff-catchers
3. Range pressure: opponents struggle to call with medium strength — they're forced into a binary "call nuts or fold all" decision

Two preconditions for an overbet:

• Range advantage + nut advantage: not only do you have higher overall equity, your top-end combos are also stronger (nut advantage)
• Opponent's range is already narrowed: usually on turn or river, after earlier streets have filtered out the opponent's weak range

Typical overbet boards: turns where a key card jumps your range forward (e.g. after BTN open + call, the turn brings a card that's exclusive to BTN's range).

Common Use Cases

• River overbet for value: you hold top-end combos (nuts) and the opponent's range has a meaningful share of bluff-catchers
• River overbet bluff: pick a hand with a blocker (e.g. blocking the opponent's nuts), low frequency but high profit
• Turn overbet: classic in BTN vs BB on certain boards (e.g. after the opponent checks, BTN overbets with the top range)
• IP-dominated: OOP overbet frequency is much lower than IP
