Goldsmith Defense Picklepuss Defense Back Rank Mate in Chess

The Goldsmith Defense Picklepuss Defense Back Rank Mate is a tactical back-rank motif where the defender’s setup (often featuring a rook on the back rank and a tight pawn/king shelter) enables a sudden mate against a king trapped behind its own pawns. In this motif, the defining feature is the opponent’s inability to escape or interpose—so a single forcing move (commonly a rook lift or back-rank capture) delivers mate.
