I've only played money for two days, online. However, I noticed I'm able to call many
hands by applying what I learned in the books and sticking to just a single table (as opposed to multi-tabling). I also have gotten into the habit of taking notes on players...I've been able to tell who steals blinds, who folds, and who plays AA-AK-KK-KJ.
Bro basically actually
apply what you learn, which is seriously much harder than it sounds, but like I said with two days experience I'm able to call em more often than not!
