Richter Veresov Attack Fork Puzzle (Rated 1372): Win a Fork — Decisive Material Gain
This middlegame puzzle shows how a single tactical shot can overturn a material edge. White’s active pieces and advanced development look promising, but Black has a forcing resource that targets multiple white pieces at once. The key idea is a fork: one pawn move creates direct threats against two important defenders, and the resulting sequence wins material while also defusing White’s initiative. In classical chess, these tactical refutations often appear when an active piece is overextended and a pin is already in the position.
