Query: 2nd Edition is Worth It

One issue that I haven't seen addressed here is the difference between the first and second editions of this book. I've had the first edition for several years, and was wondering if the second edition was revised enough to make it worthwhile. After finally breaking down and buying the new edition, I'd say that it was worth the money. Although much of the advice is the same, the pre-flop play section has been substantially changed. In general, Jones recommends playing many hands more aggressively (i.e. raising instead of calling) pre-flop than in the first edition. Given that a single 3/6 hold 'em pot is often larger than the cost of the book, an upgrade from the first edition is an easy call.
