关位干燥河牌偷池（CO River Steal Dry）

Term Interpretation

“CO River Steal Dry” is a high-level steal strategy in Texas Hold’em, consisting of three elements: position (CO), street (River), and board texture (Dry). CO refers to the cutoff, the seat to the right of the dealer, which has the advantage of acting last on the river; River refers to the fifth community card, the final betting round after the flop and turn; Dry refers to a dry board texture, typically one with no possible flush or straight draws (e.g., K♠7♦2♣9♠3♦, where only one-pair hands are likely).

Strategy Principle

On a dry river board, made hand ranges are very clear. Most of the opponent’s draws have missed, and hand strength is easily defined (such as top pair, two pair, trips, etc.). Since dry boards rarely complete draws, opponents who have not made a hand are less willing to call. The CO position is advantageous on the river, allowing a bet after the opponent checks, or a raise if the opponent bets. The core of the steal is to use positional advantage and board structure to pressure opponents with medium-strength or unimproved hands into folding.

Applicable Scenarios

• The opponent shows a weak range on the flop and turn (e.g., frequent checking, calling without raising).
• The river card is a high card or a blank that does not complete any obvious straight or flush draw.
• Your own range may include a small number of nut hands (e.g., sets, top pair top kicker) to balance the steal action.
• The opponent has a high fold frequency, especially when facing a large river bet.

Notes

• Avoid using this strategy when the river completes obvious made hands (e.g., straights, flushes), because the opponent’s made hands may become concealed.
• Bet size is usually large (about 70%–100% of the pot) to maximize fold equity and align with the value bet sizing of your strong hands.
• Frequency should be appropriate; overusing it will allow opponents to adjust their calling ranges.
• It is necessary to consider your overall range balance. If you always steal on dry boards, opponents will learn to bluff-catch in similar situations.
