The King's Indian Attack is a very popular system of development for White, which can be used against many defences. It's easy to learn and play, and is based on understanding ideas rather than move memorization. The King's Indian Attack usually involves a deliberate and sustained attack on the black king, which often proves to be highly effective and difficult to defend against. In this book Grandmaster Neil McDonald examines in depth the many variations of the King's Indian Attack. He outlines White's most promising options and Black's best defences, and provides answers to all the key questions.
