Alapin Skewer Chess Puzzles

The Alapin Skewer is a tactical motif where a more valuable piece is attacked along a line, forcing it to move and exposing a less valuable piece behind it. In practice, the key feature is a line attack on a king, queen, or rook that leaves a piece behind it vulnerable once the front piece shifts away. It often appears after a forcing move such as a check, capture, or discovered attack opens the line.
