I was 0-3 against this player in games from 3-4 years ago in which I attained a clear if not winning advantage, but fell for some trick or swindle while being annoyed by various off-the-board tactics. This player engages in "total war" during his games-- i.e., by "adjusting" the pieces during an opponent's long think or, while the opponent is away, extending his legs under the opponent's chair and not moving them when the opponent returns. Anyway, this game was my long overdue revenge.
"During a chess competition a chessmaster should be a combination of a beast of prey and a monk."
My notorious swindler of an opponent simply missed 12...Na5 and 15...d4, each of which wins a whole piece.
