What is a bishop skewer in chess?

A bishop skewer attacks a more valuable piece first, usually the king, while a less valuable piece sits behind it on the same line. Once the valuable piece moves, the bishop can capture the exposed target. It is similar to a pin, but the front piece is attacked directly and must respond.

How do I spot a skewer in a chess endgame?

Start by examining all forcing checks and look along the bishop’s diagonals. Identify pieces aligned behind the king, queen, rook, or another high-value target. Then calculate whether the king’s legal replies leave the rear piece undefended or capturable.

Why are checks so strong in a bishop endgame?

A check restricts the opponent’s choices and often forces the king away from defensive duty. That displacement can uncover an attack on another piece or pawn. In sparse positions, one tempo frequently decides whether material is saved or lost.

What is the difference between a pin and a skewer?

In a pin, the rear piece is valuable enough that the front piece cannot move without suffering a major loss. In a skewer, the front piece is the immediate target and moves away, exposing the piece behind it. Both tactics rely on alignment, but the order of attack is reversed.

How can I improve my chess endgame calculation?

Train yourself to list forcing candidates before considering routine moves. For each candidate, calculate every legal reply, then check whether the move creates a follow-up attack. In bishop endings, pay close attention to diagonals, king mobility, and pieces that appear defended but lose protection after a king move.
