Richter Veresov Attack Intermediate Puzzle (Rated 905): Win Material — Discovered Attack

This chess endgame puzzle shows how a single forcing move can create a discovered attack and win material. Black’s pieces are coordinated around the white king and the loose rook on the a-file, so the key idea is to use the knight as a tactical decoy. Once the knight is challenged, the rook behind it becomes active with tempo. In classical chess, these patterns often decide simplified positions because one tactical shot can convert a small edge into a decisive material gain.
