NL section in one and two are exactly the same. Maybe one or two new paragraphs. Do I like SSII. Read my posts. It's one of the most important poker books I own. Out of date, no, I don't think so. It's like anything, you have to read it and apply it to YOUR game, not try to play strictly by that book. I mean, you wouldn't anyhow, you always vary your play. If you don't have either, buy SSII because of the other games written about.
