The most likely start will be INTRAstate poker, and since I'm in Nevada, I expect them to be on the forefront. I have been grinding some on Merge, but I REALLY dislike their software. On PokerStars, I could grind up to 24 cash tables at once, but on RPM (Merge) the focus problems limit me to about 8 games at most before lag becomes a problem. I am SO looking forward to the return of PokerStars, where I am almost at my goal of 1,000,000 in play money before they return... currently at just over 950k.
I have started playing in the Nevada Poker League with some friends, as you can win some seats to some local tournaments for real cheap. No entry fee, but we typically tip the dealer up to $5 a piece for their time and for putting up with us ;) I'll post the info here for any locals that want to join us:
