Learn How to Skewer: Decisive Material Gain
This middlegame puzzle is a classic example of a short skewer: a valuable piece is lined up behind a more exposed target, so one forcing move creates an immediate material win. White’s attack works because the king is vulnerable and the black queen and rook are awkwardly placed. The key idea is not just checking the king, but using the check to force a reply that leaves a higher-value piece hanging behind it.
