Query: Killer Poker - Waste of Time

I was disappointed after reading this book. Too many basic concepts were discussed and i really gained nothing from the purchase.In conjunction i purchased Advanced holdem by sklansky and that was amazing i have learnt a great deal from that bookkiller poker was just a summary of how to play online. a good book if you have never played online before. otherwise dont bother.
