Chess Tactics: The Skewer (Linear Attack)

The Chess Skewer — Reverse Pin Mechanics

A skewer (sometimes called a linear attack or 'shish kebab') is a tactical motif that operates like a reverse pin. In a skewer, your long-range attacking piece (bishop, rook, or queen) targets a highly valuable enemy piece (such as the king or queen), which is directly in front of a less valuable or undefended friendly piece on the same line.

Because the valuable piece must move to avoid capture or respond to check, it is forced to step aside, exposing the defender behind it which you then capture. Skewers are highly effective in open endgames where rooks and bishops control entire diagonals and files. Practicing skewering puzzles trains your geometric calculation and board vision.

Key Features of a Skewer

• Geometric Alignment: Two enemy pieces are lined up on the same diagonal, rank, or file.
• Relative Value Order: The high-value target is positioned in the front, and the lower-value target is behind it.
• Clear Paths: No blocking pawns or units impede your long-range attacker from striking the line.
• Check Skewers: The most forcing type, where the front target is the king, making the defensive response highly restricted.
