For me, I usually stick to tournaments, over cash games.
A number of years ago, I played quite a few cash games, but pretty well abandoned it. Not because I was a lousy player, it's because I would be a good player for many
hands, and after playing for a couple of hours,a lousy player for one hand.
If I can last that long tournaments, I'm usually in the money, and can't blow it by being stupid.
