CO WSD

Overview

CO WSD is a poker statistic that stands for "Cutoff Went to Showdown." It measures how often a player who is in the cutoff position (the position immediately to the right of the dealer) sees a showdown after the flop. It is a positional variant of the general WTSD (Went to Showdown) stat, which tracks showdown frequency regardless of position.

Usage in Analysis

CO WSD is used in player profiling and hand analysis. A high CO WSD (e.g., >45%) suggests that the player is passive or calling down lightly from the cutoff, often showing down weak hands. A low CO WSD (e.g., <30%) indicates aggression—they either win without showdown or fold before reaching it. Comparing CO WSD to overall WTSD helps identify positional adjustments: if CO WSD is significantly lower, the player may be stealing blinds or c-betting and folding often.

Typical Values

In online 6-max games, a typical CO WSD for a tight-aggressive (TAG) player is around 35-40%. Loose-passive players may exceed 45%, while loose-aggressive players might stay below 30%. These numbers are approximate and vary with game dynamics, stack sizes, and opponent tendencies.

Limitations

• Sample Size: CO WSD requires a large sample (several hundred hands per position) to be reliable.
• Context: It ignores preflop action, board texture, and stack depth. A high WSD might result from many flops with draws that miss.
• Positional Adjustment: Some players intentionally show down more from late position to build a loose image, then exploit it.

Conclusion

CO WSD is a niche but valuable stat for understanding a player's showdown frequency from the cutoff. It complements other positional stats like CO VPIP and CO PFR to paint a fuller picture of their strategy.
