Indian Defense Budapest Defense Fork Intermediate Puzzle (Rated 885): Win with a Fork — Decisive Material Gain
This middlegame puzzle is a classic example of tactical refutation based on king safety and piece activity. White’s pieces look active, but the king in the center and an undefended piece create a vulnerable target. Black can exploit the alignment of the queen and rook to win material with a forcing check, then continue the attack by taking another loose piece. In classical chess, these positions reward accurate calculation over general principles.
