In my attempt to move to cash games, i am finding that after a while, i am losing concentration. It seems that trying to grind up at 2NL, i sometimes loose concentration. I am trying to insure that i have a proper playing environment but i tend to start surfing net or reading message boards or whatever. So my question is, do you monitor your session length based on time, hands, winnings or loosings?? How do you maintain proper focus? I tried multi tabling (2)for a 50 hand per table session and that seemed to help me maintain focus but i don't know that my game is ready for that. Thoughts, ideas, helps??
