Grandmaster Sergey Kasparov presents an original and shrewd opening for Black against 1.e4, the most popular opening move among amateurs. After Black's third move, White is confronted with a stark choice: either to continue on the road of the calm Philidor Defence, or to immediately gain almost two tempi by forcing Black into an endgame that looks better for White, if not close to winning. This second option, however, is a treacherous road. White will walk into the Philidor Swamp in which he runs a big risk of getting stuck. Sergey Kasparov's style is fresh and humorous. He does not bother the amateur reader with variations of 15 or 20 moves deep, but concentrates on the plans and counterplans for both Black and White.
