按钮位河牌干燥漂浮（BTN River Float Dry）
On the button, a float bluff on a dry river board, i.e., betting with a hand that has no showdown value, attempting to force the opponent to fold.
Term Background
This is a compound term derived from position (BTN, Button), street (River), strategy (Float), and board texture (Dry). While "Float" traditionally refers to calling on the flop and bluffing on the turn, in practice players also use similar logic on the river: after an opponent shows weakness, they bet with air on a dry board that lacks drawing possibilities.
Strategy Principle
On a dry board (e.g., K♠7♦2♣), the opponent's range contains few made hands. If the opponent has shown a weak range before the river (e.g., checking multiple times), the Button player can bet with any two cards, leveraging position to apply pressure. The key is to estimate the opponent's fold probability and avoid being called.
Applicable Scenarios
- Opponent is tight-passive or prone to folding.
- The board has no obvious made hands, and actions on the flop and turn indicate a limited opponent range.
- When your own range contains many value hands, mixing in bluffs helps achieve balance.
Notes
This is not a standard term but rather a situational description used among players. When executing, consider opponent tendencies and pot odds to avoid overuse.
