Nimzowitsch Defense Colorado Countergambit Puzzle (Rated 1249): Win Material — Decisive Middlegame Tactics

This middlegame puzzle is about converting activity into a decisive material gain. Black’s queen is active near White’s king and creates immediate pressure on loose pieces, especially along the c-file and the f-file. The key idea is to use a forcing check to drag the white king and defenders into awkward squares, then exploit the alignment of the queen, bishop, and rook. In classical chess, these tactical shots often decide long middlegame battles.
