Checkmating the enemy king is the ultimate goal in chess. In this book Simon Williams helps readers to practice and improve their skills in this vital area of practical chess. A mating attack typically involves a build-up of forces, followed by an opening of lines, often involving a sacrifice. Once the enemy king is exposed, it is either checkmated, or only saved at a great cost in material. The puzzles in this book are pertinent to all these phases, and involve questions of where to attack and what pieces to use. Topics include: Attacking the king caught in the centre; Central breakthrough; Standard sacrifices against the castled king; Chasing the king; Endgame mates; Combinative themes.
