A game from the 2007 Wellington Chess Club Championships

International Master Anthony Ker and I played this game in the 2007 Wellington Chess Club Championships. The advantage went back and forth, until the endgame when White was forced to sacrifice his knight to stop Black’s central pawns. White’s king was corralled when Black’s king advanced up the board.
