Blumenfeld Countergambit Accepted Other Variations Puzzle (Rated 1786): Win Material — Crushing Middlegame Tactics

This Blumenfeld Countergambit Accepted puzzle shows a classic middlegame where king safety and loose pieces decide everything. Black’s queen activity on the g-file creates immediate pressure against White’s king and exposed first-rank pieces, while the rook and bishop coordination turns tactical threats into a forcing sequence. The key idea is not a quiet positional squeeze but a decisive tactical conversion: exploit the undefended pawn, force the king into awkward defense, and simplify into a winning material edge.
