WTSD from CO
WTSD from CO
The percentage of hands a player voluntarily goes to showdown when they are seated in the cutoff position, calculated as hands seen to showdown divided by total hands played in cutoff that were not preflop folds.
Overview
WTSD from CO (Went to Showdown from Cutoff) is a positional statistic used in online poker tracking software (e.g., PokerTracker, Hold'em Manager). It measures how often a player sees a showdown when they are in the cutoff seat (CO), relative to the total number of hands they played from that position (excluding preflop folds).
Calculation
WTSD from CO = (Number of hands from CO that reached showdown) / (Number of hands from CO where the player saw the flop or later). It is expressed as a percentage. Example: If a player has 100 hands in cutoff where they did not fold preflop, and they go to showdown in 30 of them, their WTSD from CO is 30%.
Typical Ranges
- Tight players: 25–30%
- Aggressive/loose players: 35–45%
- Very loose-passive players: 45%+
Note: Extremely low WTSD (below 20%) may indicate a player folds too often postflop, while very high WTSD (above 50%) can signal a calling station tendency.
Strategic Implications
-
Exploitation: A high WTSD from CO suggests the player goes to showdown too often, making them vulnerable to value bets and bluffs in large pots. A low WTSD means they fold easily, so you can bluff them more frequently on later streets.
-
Range Analysis: Combined with VPIP (Voluntarily Put Money In Pot) and PFR (Preflop Raise), WTSD helps define a player's postflop tendencies. For example, a CO player with high VPIP/PFR but moderate WTSD is likely aggressive and may be overplaying medium-strength hands.
-
Context Matters: Always consider sample size. A 30% WTSD from CO over 50 hands is less reliable than over 500 hands. Also, the statistic is position-dependent—players tend to have higher WTSD from late positions because they have more information and play weaker ranges.
Related Statistics
- WTSD (Overall): The global version excluding positional breakdown.
- W$SD (Won Money at Showdown): The percentage of showdowns won.
- Folded to River Bet: Complements WTSD by showing how often a player folds before showdown.
Limitations
- WTSD does not differentiate between showdowns where the player was the aggressor versus a caller.
- It ignores the hand strength shown; a player might have a high WTSD but rarely win at showdown.
- Works best when combined with aggression factor (AF) and W$SD for a complete picture.
In summary, WTSD from CO is a key metric for understanding a player's showdown frequency from a specific late position, helping you adjust your strategy against their tendencies.
