Well it really depends, if im playing a few tournaments and i run deep in one and that one took lets say 6-7 hours im done after that, you mentally get tired after such a long run, probably the a break next day aswell and play the day after that.
but if i play sit&go's for 2-4 hours its fine maybe few hours later play 1 or 2 more
or sometimes when you get rivered in a few tournaments in 1-2 hours i'll just stop playing and do something else, sometimes you just feel its not going anywhere and you dont really wanna play if you're not feeling it and play tilted.
