A Triumph of Technique by FM Dennis Monokroussos
The late Aleksander Wojtkiewicz never reached the absolute elite of world chess, but he was a strong grandmaster capable of beating just about anyone. His score against former FIDE World Champion Alexander Khalifman, for instance, was an undefeated 3-1, and in this game he outplayed and defeated him as if he weren't even a grandmaster, let alone a member of the elite. The isolated d-pawn often gives its possessor good prospects for active, even attacking play in the middlegame, but it can become a weakness in an ending. That's what happened here, and because Black had a second weakness Wojtkiewicz was able to win in beautiful, textbook style.
