Maxim Matlakov (Black) Puzzle: Win — Material
This chess endgame is a lesson in converting a material advantage while respecting an active enemy rook. White has an extra knight, but Black’s rook creates counterplay by attacking a loose queenside pawn and supporting a dangerous passed pawn. The key strategic idea is to improve king safety first, then use rook activity to challenge the advanced pawn. Once the immediate threat is controlled, White can simplify and preserve the decisive material edge.
