After a lifetime of playing 3-4 per year home games, I started playing on-line about 2 1/2 years ago and I play 95% stud.

Originally, and at .25/.50 tables on PokerStars, I was seeing 4th street between 55-75% of the time per session! Incredibly, and probably due to luck, I was holding my own. This made it sort of difficult to learn but then I read 7 Card Stuf by Roy West.

My game is more at the 25-30% 4th st call rate now and I regularly play 1/2, 2/4 and 3/6 tables. Positive EV has, er, yet to materialize at 5-10 tables and beyond!

BTW, I've also read Theory of Poker but I still have not put my hands on 7CS4AP.

Cheers
