If you're just interested in NLHE cash games, then SS2 is definitely not a must-have. That section basically says: bet often, bet big, and keep on betting. Play hands like 56s preflop to a raise, and check/raise big with them if you catch any part of the flop at all, from the made straight or flush or two pair right down to bottom pair or a gutshot. Yep, you too can play like Doyle.

But it's got a lot of information on a lot of other games. That stuff is fun to read, although I have never used any of it.

Then get SS2!

Or, at least, the advice for those games seems good to me. It's written by experts. But I personally know zip about those games so my recommendation is worth about zip....
