Well I still keep it at one table at a time I'm a beginner tho, never tried multiple tables )
Both tournaments and cash I always choose to play up to a maximum of 4 tables. From then on, my way of thinking gets complicated and I don't like to play like a robot.I mean actually play without dragging down other games or just being a pain making people wait for you.
My current limit is two, I know that is not much. When I am play 3 games they all suffer and I make really big mistakes, I end up sabotaging one game to save the others. For me two is comfortable. I am asking because I assume every time we have to wait on a player over and over again, I assume he is playing in multiple games.
