Modern Defense Semi Averbakh Variation Puzzle (Rated 1190): Win Material — Decisive Middlegame Tactics

This modern defense middlegame features a sharp tactical imbalance where Black’s active queen and bishop create immediate pressure on White’s queenside and king safety. The key idea is to notice when a seemingly active white piece can be undermined by a forcing capture that opens lines against the queen and rook. In positions like this, material is not the only factor: loose pieces, pins, and exposed coordination can turn a normal-looking middlegame into a decisive tactical win.
