[disjunction]

I used it in a PokerStars play money tournaments when I was first starting out [Summary of play money tournments as of 2 years ago: almost everybody tries, but a lot of players are terrible. Actually, by sticking to preflop poker, you're playing against the strongest part of their game]. It worked great. In the beginning I got called with smaller cards and doubled up. In the middle I kept stealing blinds. I finished 12th out of a couple thousand.

But opponents who know how to play will have a large (for poker) advantage on you. It's easy to see how to improve on the system, because it was oversimplified for the book. But if you're capable of doing that you're capable of playing good postflop poker anyway.
