W$SD

[wahooriver]

I have just once again examined this statistic in 2 databases. This is not a statistical look - but just a gestalt impression. Winners in my database have >50% W$SD frequently and losers frequently have less.

This may well be a good statistic once you have enough data on a player (maybe 500 hands). My reasoning:

1. W$SD % suggests that the caller (or bettor) is not clueless.
2. Good players know when to fold, and thus are more likely to not even get to the river without having a reasonable winning probability.
3. Bad players (and I occasionally fit this mold) bluff too much on the river - the only get called or raised by good hands - thus when they win the results do not contribute to W$SD, but when they lose - the % decreases.

I would love to see someone with large database numbers crunch this for us.

The W$ when bet or raised the river (DO I call)
Went to showdown, taken in context of their VPIP (Do I bluff), and
W$ at showdown and check-raise (Do I make thin value bets)

are all important stats for once you get a lot of hands on an opponent and hshould be viewed/thought about collectively.
