Skewers in Chess: Complete Guide
A skewer is the reverse of a pin: you attack a valuable piece along a line (rank, file, or diagonal), and when it moves, you capture the less valuable piece behind it. Skewers are most common with bishops and rooks, and they win material in positions where the opponent's pieces are aligned.
How skewers work
A skewer requires three elements:
- An attacking piece (bishop, rook, or queen).
- A valuable target piece in the line of fire.
- A less valuable piece directly behind it on the same line. When the front piece moves to escape, the back piece is captured.
Example: a bishop on a1 checks the king on d4, the king moves, and the bishop captures the rook on h8.
Rook and bishop skewers
Rook skewers happen on open files and ranks, rook checks the king, wins the queen behind it. Bishop skewers happen on diagonals, especially in endgames where pieces line up. Both are deadly in the endgame when pieces have fewer escape squares.
Training
Practise recognising skewer opportunities in tactical puzzles. Key pattern: look for two pieces on the same rank, file, or diagonal with an empty path between them.
