The Skewer: A Reverse Pin

What is it?
A tactic where an attacking piece threatens a valuable enemy piece, which must move to safety, thereby exposing a less valuable piece behind it on the same line of attack.
How to Identify
Look for two enemy pieces on the same rank, file, or diagonal. The *more* valuable piece must be in front of the *less* valuable piece.
Why is it Important?
Skewers are a fantastic tool for converting an advantage or punishing poorly placed pieces. They are particularly powerful in open endgames with rooks and queens.

How to Execute Devastating X-Ray Attacks

From Good to Great: Pro-Level Tips

The King is the Ultimate Target

The most powerful skewers are those that start by checking the king. This forces the king to move, guaranteeing that you will be able to capture the piece that was behind it. Always look for checks that create a skewer.

Rooks and Queens Rule the Skewer

Because skewers operate on straight lines, the long-range power of rooks and queens makes them the perfect pieces for this tactic. Bishops can also deliver skewers, but they are less common.

A Move That Made History: Sultan Khan vs. Capablanca, 1930

This simple theoretical position perfectly illustrates the power of a skewer. If it were Black's move and they played Ke3, White would respond with Re2+, checking the king. The king is forced to move off the e-file, and White captures the rook that was on e8. It's a textbook example of how a check can lead to a devastating skewer, a common theme in rook endgames like the one played by these legends.

The Winning Combination: This is a theoretical position demonstrating the concept.

Common Mistakes in Skewer Puzzles

Reversing the Targets

Trying to skewer a less valuable piece to get to a more valuable one; that is a pin, not a skewer.

Missing In-Between Defensive Moves

The front piece might move away while giving a check or defending the rear piece simultaneously.

Failure to Check All Diagonals

Overlooking long-range Bishop skewers that span the entire board.

How to Solve Skewer Puzzles

1

Find Linear Alignments

Look for two enemy pieces on the same line (rank, file, or diagonal).

2

Verify Target Priority

Confirm the piece closer to you is the more valuable one.

3

Attack the Front Piece

Deliver the check or attack that forces the front piece to step aside.

4

Snatch the Prize

Capture the second piece once the first one has moved.

Why Skewers are "X-Ray" Tactics

Skewers require "X-Ray vision" to see past the immediate target to the vulnerability behind it. They are most deadly in endgame scenarios where the board is open.

Frequently Asked Questions

What is a skewer in chess?

A skewer, also called an X-ray attack, is a tactic where an attacking piece threatens a valuable enemy piece. When the valuable piece moves away, a less valuable piece behind it is exposed and can be captured.

What is the difference between a pin and a skewer?

They are inverse tactics. In a pin, a less valuable piece is in front of a more valuable piece, and cannot move. In a skewer, a more valuable piece is in front of a less valuable piece, and is forced to move.

Which pieces can perform a skewer?

Only long-range pieces that move in straight lines can perform a skewer: the queen, rook, and bishop.
