WSD from CO
WSD from CO
Term: Cutoff Showdown Win Rate WSD from CO The frequency of entering showdown from the Cutoff position and winning, i.e., the showdown win rate from that position.
Definition and Calculation
WSD is the abbreviation for "Won at Showdown", referring to the player's winning percentage when reaching showdown. "WSD from CO" specifically refers to the winning percentage when the player is in the cutoff position (CO, the first seat to the right of the dealer), enters the pot, and reaches showdown.
Calculation formula: WSD from CO = (Number of times the cutoff entered showdown and won) ÷ (Total number of times the cutoff entered showdown) × 100%.
Statistical Significance
This metric reflects the player's actual showdown profitability in the cutoff position. The cutoff is one of the first positions after the blinds to have a positional advantage, typically with a wider opening range. Therefore, a reasonable WSD range is lower than that of positions like the big blind (which is often forced to defend). Generally, a WSD from CO between 45%–55% is common; values outside this range may indicate overly loose or overly tight play.
Influencing Factors
- Game type: In cash games, WSD may be slightly lower with deep stacks due to more bluffing; in tournaments, WSD may be higher due to ICM pressure.
- Opponent skill: Against aggressive opponents, showdown win rate may decrease (being bluffed out of pots).
- Personal style: Tight-aggressive players (TAG) typically have lower WSD from CO than loose-aggressive players (LAG), as the former enters pots with stronger hands, but the latter forces opponents to fold through continued betting.
Relationship with Other Metrics
- If WSD from CO is too high (e.g., >60%), it indicates the player rarely bluffs or value bets aggressively enough from this position, potentially missing value.
- If WSD from CO is too low (e.g., <40%), the player may be over-bluffing or calling too loosely, making it easy for opponents to fold or exploit.
- Combined with VPIP (Voluntarily Put Money In Pot) and PFR (Preflop Raise), a more comprehensive assessment of cutoff strategy can be made.
Notes
With small sample sizes, this metric fluctuates greatly. It is recommended to analyze at least 500 hands of data. Additionally, standard ranges vary by stakes and game type, so they should not be applied rigidly.
