I have not read SS1. However, I would expect 2 to have more insights. I own 2 and have read the hold-em and Tourney sections numerous times (though not in a couple years, so Ill be reading them again this month). It is so massive because of all of the other games. I have probably studied (read multiple times, taking notes) 200-300 pages of it, not all of it. I havent messed with triple draw or stud yet, those are still around the corner. But get one of the copies of SS. Now. NOW.
