Learn How to Crush the Defender: Tactical Material Gain
This puzzle is a classic middlegame tactical sequence built around capturing a defender and then using a discovered attack to win material. The key idea is that one piece is overloaded: it must protect a critical square while also guarding a more valuable target. Once that defender is removed, the position collapses because the remaining pieces are aligned on the same file. In classical chess, these motifs often appear when rooks and queens are stacked on open lines.
