Eugenio Torre (Black) Puzzle: Win Material — Rook

This chess endgame demonstrates how a concrete material gain can decide the position. White’s rook is highly active near the enemy king, while Black’s exposed king and weak pawn structure create tactical opportunities. The key idea is to identify an undefended pawn, use check to gain time, and then collect additional material. Once the rook becomes active, White’s extra material and pressure make the position decisively easier to convert.
