枪口+1位摊牌率（WSD from UTG+1）

Overview

[WSD] from [UTG+1] is a specific positional statistic in poker data analysis that combines position information with showdown behavior. [WSD] (Went to [Showdown]) indicates the percentage of hands that reach showdown after entering the pot, while [UTG+1] is the second action position preflop (immediately to the left of the big blind, after the [UTG]).

Statistical Meaning

This metric measures the percentage of hands that a player takes to showdown after voluntarily entering the pot from the [UTG]+1 position (typically by calling or raising). The calculation formula is usually: Number of hands voluntarily entered from UTG+1 that reach showdown / Total number of hands voluntarily entered from UTG+1 × 100%.

Strategic Significance

• High WSD from UTG+1 (e.g., > 40%): Indicates that the player is more inclined to go to showdown with strong hands from this position, possibly lacking the ability to fold or often holding value hands. Opponents can apply pressure on the river against such players, as they are unlikely to fold.
• Low WSD from UTG+1 (e.g., < 25%): Suggests that the player folds frequently from UTG+1, possibly only entering the pot with very strong hands or giving up easily postflop. Opponents can increase their continuation bet frequency, as the player will often fold.

Applicable Scenarios

This statistic is commonly used in online poker [HUD] (Heads-Up Display) to help identify an opponent's playing tendencies. However, a sufficiently large sample size (typically at least a few hundred hands) is needed for it to be reliable. It should be combined with other metrics (such as [VPIP], [PFR], [AF]) for a comprehensive assessment.

Notes

• The UTG+1 position is early in the preflop action, and players usually enter with a tighter range, so the average WSD from this position is higher than from later positions.
• Statistical data can be influenced by factors such as flop structure, opponent style, and [stack depth]; it should not be relied upon in isolation.
