After a week of two tabling I'm going back to just one for now. My bb/100 stats dropped substantially. Kinda the opposite of what you would think, but I found myself betting even more in shady positions with meh cards.
I Played 2 tables once and as a beginner it was pretty craz. Now I play one game at a time.
I have to say i enjoy having u multitablers at my table especially if u are sitting to my immediate right or left. You seem to fold very frequently and if u do bet i'm pretty sure your not bluffing Your too busy watching the other tables.
In cash I play 2-4 zoom tables, if I have time play 2 zoom tables and 2-4 tournaments. Used to mass multitable sitngoes back in the day on stars, that was fun.
