I'm writing this review mostly to give a counterpoint to the review below. Unfortunately, Mr. Thompson missed the point. This is not meant to be a book on tactics, but rather on finding a plan in the middlegame. The positions you'll see here are positions that might even appear in our own games, rather than only those of GM's. The idea is to chose, from among five choices, the best plan of action. These plans won't neccessarily win the game outright, but they'll lead to an advantage. In that respect, the book is excellent, and as far as I'm concerned, essential for a player who's got a good grasp of tactics and wants to take the next step. Along with Bronstein's Zurich International '53, this is one of the best books on middlegame planning I've seen; practice makes perfect.
