English Opening Myers Defense Puzzle (Rated 1244): Win Material — Rook Tactics

This middlegame puzzle is about recognizing when an active rook can create a decisive material gain by invading the first rank. The key idea is that checks on open files often force the opponent’s king and heavy pieces into awkward coordination, especially when the king is exposed and several pieces are loose. In positions like this, tactical motifs such as discovered attack, skewer, and hanging piece punishment can turn a small initiative into a clear advantage.
