English Opening The Whale Puzzle (Rated 1279): Skewer — Decisive Material Gain

This middlegame puzzle is built around a short skewer against the king and a loose back-rank target. Black’s active bishop and queen coordinate to create a forcing sequence that wins material by attacking the king first and the more valuable piece behind it second. The key idea is that a check can be more than a king move: it can also expose a hidden tactical target. In positions like this, king safety and piece alignment matter more than raw material.
