re: Poker & Multi-tabling
I started at one table, and eventually worked my way up to *drumroll* 3. I still play best at one table, able to boast a significant win rate which comes from focusing on one hand. I have a much higher % of hands played than most regs though (probably about 3x as much), and have an uncommon LAG style.
Were I to tighten down, I'd be comfortable playing four, but it's not the game I like, and I'd need a better set-up than my current internet connection and monitor.
