pending on the game. I'm still learning, so most tables I played that felt comfortable was two. I tired 4 one time, but it was chaos - you have to have your strategy and decision-making process in your pinky - I'm not there yet. (One time I went all in because I thought I made Stright flash, just to "combine one table whole cards with the other table flop, lol.) Mostly, I play one table when I'm trying to focus and learn. Occasionally, I'll play two tables when I'm just grinding $10NL as practice multi-tabling.
