WTSDThe WTSD (for Went to Showdown) tells in how many percent of cases where a player saw the second betting round that he also went to the showdown. In Hold'em, this would indicate how often a player saw the showdown, given that he saw the flop. It is a measure for how inclined a player is to give up his hand after the flop. The higher the value, the more rarely he will do this. This could mean that one should bluff him less and raise him with a good hand to get the most value out of him.
