Frank Marshall (Black) Puzzle: Capture — Rook Tactics

In a chess endgame, material threats often matter more than elaborate attacking plans. Here, an enemy knight has ventured deep into White’s camp while a pawn attacks two white pieces at once. The key is to assess the entire exchange sequence rather than react automatically to the fork. A rook can often capture an exposed minor piece, creating a decisive material gain even if the opponent then wins a bishop. This is practical classical chess: calculate captures to their final balance.
