A skewer attacks a valuable piece so it must move, revealing a second target behind it. Unlike a typical pin, the more valuable piece is attacked first and the piece behind is captured afterward.

How can I win material after an inaccuracy?

Look for newly exposed queens, pinned defenders, overloaded pieces, and loose back-rank targets. Calculate forcing continuations carefully, including every legal recapture, before choosing the material-winning line.

What is the difference between a pin and a skewer?

In a pin, the less valuable piece is attacked first and cannot move because a more valuable piece is behind it. In a skewer, the valuable piece is attacked first and moving it exposes the piece behind.
