河牌浮（River Float）

Concept

River Float is a post-flop play in Texas Hold'em, extending the "Float" strategy. Float typically refers to calling on the flop or turn with a weak hand or draw, intending to steal the pot by betting or raising on later streets. River Float specifically refers to calling on the river when a player holds a marginal hand (such as medium pocket pairs, top pair weak kicker, etc.) or just a pair, to call and oppose an opponent's bluff.

When to Use

• Opponent's range contains many bluff combinations, and their bet sizing is small or medium.
• The board structure is unfavorable for opponent's value hands, e.g., draws that missed.
• You hold a hand that can beat opponent's bluffs but is not strong enough to beat opponent's value hands.
• Opponent is an aggressive player who often over-bluffs on the river.

Risks and Notes

• The success of a river float depends on accurately assessing the opponent's bluff frequency. Over-calling can lead to being exploited by value hands.
• When opponent bets large, pot odds become unfavorable, requiring more reliable reads.
• River floats usually need to consider the action history on flop and turn, e.g., whether the opponent's story of consecutive bets makes sense.

Differences from Similar Concepts

• "Hero Call": Similar in meaning to River Float, but Hero Call emphasizes making a difficult call with a medium-strength hand on the river, while River Float is part of the Float system.
• "Value Call": Refers to calling with a strong hand, not a marginal hand.
