like really, how can you guys do that? when I see someone in my table playing multiple tables I see them as tight aggressive players, because I think with 10+ tables you'd probably just wait for a good hands, just my opinion but what play style would they do with multiple tables?
play for 10 tables is very convenient, you can hedge yourself and do not need to waste time waiting for the next hand, distributions go without stopping
I know when I used to play 16+ cash tables I did it because I would make more playing multiple tables at 1BB or 2BB/100 than I would playing 2 tables and winning at 6BB or 8BB/100.
But yes identifying who is multi-tabling and trying to find spots to exploit this is definitely a viable strategy - they won't be playing as well at each individual table IMO.
