Killer Poker has very little practical information on the mechanics of playing poker. It doesn't advise you when to play, raise, fold, or bluff. Rather, the advise it offers can be boiled down to, play aggressive and always try to be aware of, and fix, your mistakes. If this book had given some method for identifying and correcting mistakes it would have been worthwhile. There are other, much better, books on poker out there.
