How do I spot a skewer in a chess middlegame?

Look for a valuable piece directly in front of another important target, usually a king or queen. If attacking the front piece forces it to move, the piece behind may become exposed. Check whether a forcing move can create or exploit that alignment.

What is the difference between a pin and a skewer in classical chess?

A pin restricts a front piece because moving it would expose a more valuable piece behind it. A skewer works in reverse: the valuable front piece is attacked first and must move, exposing the less valuable piece behind it.

How can I defend against a pinned piece?

Do not assume the pinned piece must remain passive. Search for a forcing move that attacks the pinning piece, blocks the line, moves the king, or creates a stronger counter-threat. Always confirm whether the pin is absolute or merely tactical.

What should I look for when king safety is weak?

Examine open files, checks, queen invasions, and pieces that are unable to move because they protect the king. Vulnerable kings often make tactical details more important than material count, so calculate forcing replies before making a quiet move.

Pin Puzzle (Rated 2159): Skewer — King Safety

A skewer attacks a valuable piece first, forcing it to respond while exposing a second target behind it. In this middlegame, king safety is the central issue: the queen and rook coordinate pressure around the exposed king, while a pinned bishop has no useful escape. The position rewards a tactical response that challenges the attacker with tempo. Instead of accepting the loss of material, look for a move that attacks the queen and changes the geometry of the skewer.
