SB WTSD

Overview

SB WTSD is a commonly used statistic in poker, representing the percentage of hands a player goes to showdown while in the Small Blind position. WTSD (Went to Showdown) measures how often a player who sees the flop ultimately reaches showdown (i.e., hands are revealed after the river). Generally, this metric is used to evaluate a player's calling or raising range from the blinds, as well as their post-flop aggression or passivity.

Calculation

SB WTSD is calculated by dividing the number of hands from the small blind that reach showdown after seeing the flop by the total number of hands from that position that see the flop. Typically, statistics require a sufficiently large sample size (thousands of hands) to reduce variance. Online poker tracking software (e.g., Hold'em Manager or PokerTracker) calculates this automatically.

Typical Range and Interpretation

• Low SB WTSD (approx. 20%–30%): Indicates a player rarely goes to showdown from the small blind, usually folding post-flop. They may prefer to fold to raises or continuation bets. Such players often play tight or are aggressive post-flop, forcing opponents to fold before showdown.
• Medium SB WTSD (approx. 30%–40%): Common among balanced players who have both some showdown value and occasional bluffs.
• High SB WTSD (over 40%): Shows a player frequently goes to showdown from the small blind, possibly calling too much or being insufficiently aggressive post-flop. A high showdown rate often suggests a wide range when stealing or defending blinds, with a tendency to show down hands, but this can be exploitable from out of position.

Note: SB WTSD should be analyzed alongside other metrics (e.g., VPIP, PFR, AF) to avoid misinterpretation. For instance, a high SB WTSD with low VPIP may indicate the player only goes to showdown with strong hands; a high SB WTSD with high VPIP may suggest excessive passivity from the blinds.

Strategic Implications

Due to positional disadvantage (acting first post-flop), the small blind position usually calls for a tighter pre-flop range and decisive post-flop decisions. An overly high SB WTSD may mean calling too often out of position, leading to long-term losses; an overly low one may indicate folding too easily, making the player vulnerable to repeated continuation bet bluffs. Ideally, players adjust their SB WTSD based on opponents' tendencies while maintaining balance.
