Query: Not a great tournament poker book.

With all of the books currently on the market about poker and, specificly tournament poker, this is not the one I would recommend. Sklansky's books about limit poker are excellent reads, however, this book is lacking of any advanced poker theory. For beginners, I would recommend any books by Tom McEvoy and T.J. Cloutier. For advanced players, I would definitely recommend the Harrington on Hold 'em books by Dan Harrington, both volumes. These are probably the best books on the market about no-limit hold 'em with some great ideas for the more advanced player. But leave the Sklansky book on the shelves.
