WSD from CO
WSD from CO
WSD from CO (Went to Showdown from Cutoff) is the percentage of hands played from the cutoff position that proceed to showdown after the flop.
Overview
WSD from CO is a poker statistic typically found in tracking software (e.g., PokerTracker, Hold'em Manager). It measures how often a player sees a showdown when they have voluntarily put money into the pot from the cutoff position and the hand reaches showdown. The acronym WSD can stand for either "Went to Showdown" or, less commonly, "Won Showdown at Showdown." In most HUDs, it refers to "Went to Showdown" unless specified as W$SD. This article assumes the standard interpretation.
Calculation and Interpretation
WSD from CO is calculated as: [ \text{WSD from CO} = \frac{\text{Number of showdowns from CO}}{\text{Number of hands from CO that saw the flop}} \times 100% ]
The denominator typically includes only hands where the player voluntarily contributed (VPIP) from the cutoff and saw the flop. Hands folded preflop or on the flop without a showdown are excluded.
A high WSD (e.g., >45%) suggests a player tends to go to showdown often with made hands, indicating a passive or calling-heavy style or a tendency to chase draws. A low WSD (e.g., <30%) may indicate frequent folding on later streets or aggressive play that forces opponents to fold before showdown.
Strategic Implications
From the cutoff, position is advantageous postflop. A player with a high WSD from CO might be exploitable by value-betting thinner on later streets, as they are likely to call down with marginal holdings. Conversely, a low WSD from CO suggests a player who folds to aggression frequently; against such opponents, continuation bets and turn barrels become more effective.
WSD should be used in conjunction with other stats like Aggression Factor (AF), Fold to River Bet, and Won Showdown (W$SD) to build a complete profile. For example, a high WSD combined with low W$SD indicates a calling station, while high WSD and high W$SD suggests a player who goes to showdown only with strong hands.
Limitations
WSD alone can be misleading without sample size. A small number of hands (e.g., <100) from the cutoff may yield unreliable percentages. Positional differences: WSD from CO may differ from overall WSD due to the cutoff's tighter range and postflop positional edge. Also, note the variance: a player short-stacked or in a tournament will have different tendencies compared to deep-stacked cash games.
