Being strong at the opening will give you an advantage, and accurate reading and calculation in the endgame can gain you many points; but excelling at the middle game is the surest way to victory. This book presents 32 crucial middle-game positions that arose in top professional games. It focuses on making clear what purpose is served by the moves played and which strategic considerations are at play.

Every position is discussed in detail, explaining what goes on in the minds of the players, showing the moves that are good, bad, or hard to judge. It makes for an entertaining journey through the realm of professional go and also gives an insight in what lies beneath many professional moves that at first may look strange.
