Harrington's play percentages; Use them, or no?
Harrington's probably not the only one (but he's the one I'm reading right now) that uses percentages for plays given particular situations. Things like, raise, 80%, call 20%, or Call 60%, fold 40%, ect.
I don't know that this is something that I need to be doing given that I don't play MTTs often and I only play ring games a few times a week. I just try to remember the higher percentage play.
But for those of you multitabling/grinding a particular limit, do you make a conscious effort to mix up your play, especially if you see there are a lot of regulars at your table? Dan says that you can lean your percentages one way or the other depending on your read of your opponent but the big part about not making the same play 100% of the time (given similar situations) is to make it difficult for your regular opponent's to read you.
If you're multitabling, doesn't that lead you to make the same play all the time simply because you're limited in the amount of time you have to make each decision?
