The Skewer
"Attack the more valuable piece — and win what hides behind it."
A skewer is the inverse of a pin: the more valuable piece is attacked first and must move, exposing an equally or less valuable piece behind it to capture. Queens and kings are most commonly skewered. Understanding skewers alongside pins gives you a complete toolkit for exploiting pieces on the same rank, file, or diagonal.
Key Ideas
- 1In a skewer, the more valuable piece is in front and must move to escape the attack
- 2After the valuable piece moves, the attacker captures the piece that was hiding behind it
- 3Rooks, bishops, and queens can all execute skewers along lines
- 4King skewers are especially powerful in endgames — the king is forced to move and material is won
- 5A skewer can win undefended pieces or even pieces that were protected but behind someone else
How to Spot It
- ✓Look for your rook, bishop, or queen aligned with a valuable enemy piece — is there another piece directly behind it?
- ✓In endgames, look for king positions where the king is on the same file, rank, or diagonal as another piece
- ✓After a long diagonal or rank becomes open, visualize what's on the other end
- ✓Any time you can check to force a king move, ask: what does moving the king expose?
How to Defend Against It
- ⚠Keep your king out of long lines of pieces in endgames — active king placement matters
- ⚠Don't leave valuable pieces on the same file, rank, or diagonal as lesser pieces
- ⚠If skewered, check if the piece behind can escape or if you have a counter-threat that gains tempo
- ⚠Occupy the line between your pieces to break the skewer

Frequently Asked Questions
What is a skewer in chess?
A skewer attacks a high-value piece directly, forcing it to move, which then exposes a second piece behind it to capture. It's the reverse of a pin.
What's the difference between a skewer and a pin?
In a pin, the less valuable piece is in front and can't move. In a skewer, the more valuable piece is in front and is forced to move, exposing what's behind it.
Can a knight create a skewer?
No. Knights jump to their destination square directly — they don't attack along lines. Only long-range pieces (bishops, rooks, queens) can create skewers.
How do I practice spotting skewers?
Train by looking at any position for all long open lines (files, ranks, diagonals) and asking whether you can place a sliding piece at one end to threaten both ends. Tactics trainers like the FireChess puzzle system include dedicated skewer exercises.
