Barnes Opening Hammerschlag Puzzle (Rated 1471): Trap the Queen — Decisive Material Gain
This middlegame puzzle is all about trapping a powerful piece and turning pressure into a decisive material edge. The key idea is to recognize when a queen has wandered into a vulnerable square near the king and can be forced into a cramped defensive role. In positions like this, active rooks, pinned pawns, and king safety often combine to make a seemingly strong queen a tactical liability rather than an asset.
