In the May 18 issue of Card Player magazine, poker pro Robert Deppe was asked what he has done to improve his game.
I started reading a lot of hand histories from all different types of players. Many players, when they try and improve, tend to study only their own game. There's only so much you can learn when focusing on your own game. You have to see many hands from as many different types of players as possible. I try to understand why my opponents make the plays that they make, and not whether they are good or bad plays. I'm more concerned about what they were thinking in a particular situation.
