This book contains 100 chess puzzles and their solutions, all of which are either fork, pin, or skewer tactics. The puzzles are intended for players of intermediate level.

• If you attack two of the opponent's pieces at the same time by using one piece, this is called a fork.
• When a defensive piece is stuck in a pin, it can't move without exposing a more valuable defending piece on the opposite side to assault.
• A skewer is an attack upon two pieces in a line and is similar to a pin.
