48... Rdd6?? Staying intact with 48...Kf7 is correct and white will faced serious difficulty to convert his extra pawn into a winning advantage . 49.Rb7! Now white is threatening checkmate with 50.g5++! 49...g5 50.Rf5+ Ke6 51.Rxg5 1–0 Two passed pawns on the kingside is too much to handle for black.
