Skewer in Chess: What It Means and How to Use It
Skewer — A skewer attacks a valuable piece that must move, exposing a less valuable piece behind it to capture on the same line.
What “skewer” means in chess
A skewer is a tactic where a bishop, rook, or queen attacks a piece that is more valuable than the piece standing behind it on the same line. Because the front piece must move to avoid capture, the piece behind it is left exposed and can then be captured.
A skewer is essentially a pin in reverse order of value: in a pin the weaker piece is in front and cannot move; in a skewer the stronger piece is in front and must move, sacrificing the piece behind it. The most common skewer targets the enemy king, forcing it to move off the line so a rook or queen behind it falls.
Skewers are especially common in the endgame with rooks and queens, where kings are exposed on open ranks and files and cannot avoid moving out of check.
How it plays out in practice
- Look for the enemy king or queen lined up with a lesser piece behind it on the same rank, file, or diagonal.
- Give check with a rook, bishop, or queen along that line to force the front piece to move, then capture what is left behind.
- Skewers are strongest in open positions and endgames, where kings and rooks are exposed on clear lines.
- Combine a skewer threat with other threats — if the opponent must also stop mate, they may not have time to block the skewer.
Common mistakes
- Confusing a pin and a skewer and misjudging which piece will actually be won — check which piece is in front before committing.
- Skewering a piece that can simply interpose a blocker on the line, saving both pieces.
- Missing that the "skewered" piece behind is actually defended, so no material is won even after the front piece moves.

Frequently Asked Questions
What is a skewer in chess?
A skewer is a tactic where an attacker (bishop, rook, or queen) attacks a valuable piece — often the king or queen — that has a less valuable piece directly behind it on the same line. The valuable piece must move out of the attack, and once it does, the piece behind it is left open to capture. It is one of the most common ways to win material in rook and queen endgames.
What is the difference between a pin and a skewer?
The difference is which piece sits in front. In a pin, the weaker piece is in front of the stronger piece and is effectively frozen in place because moving it would expose the stronger piece. In a skewer, the stronger piece is in front and is forced to move because it is in check or under direct attack, exposing the weaker piece behind it to capture. Both use the same rank, file, or diagonal geometry, just with the pieces in opposite order.
Can a skewer happen without check?
Yes. While the most forcing skewers involve check against the king, a skewer can also target a queen or rook that is simply more valuable than the piece behind it. The front piece is not legally forced to move, but it almost always should, since staying put loses more material than retreating. These are sometimes called relative skewers, similar to a relative pin.
