You may just be a [gasp] losing player. If you've played 20-30 SNG games up to this point and have only cashed in one of them this may be the case. It's hard to say for certain without a larger sample.

What books have you read and what do you plan to read? Do you feel you have any strong points to your game? Anything you know you need to work on?

It's good to figure out where you stand and analyze your own play. Try to figure out where your leaks are and plug them. I know from your previous posts that you have PT - go through your hand histories in the replayer and analyze your own play.

I notice you've made a lot of hand posts in the SSSH forum but nothing here yet. Any reason why?
