Check-mate, a delightful sight on board


Generally the pieces combine and most often are led the queen with the help of major and minor pieces to set up an attack.

The game which follows - is a delight to go through as White here, shows plenty of pluck and ambition in cornering Black’s King with the limited remaining pieces on board, after the exchange of queens. Thecombination starts after a  beautiful bishop sacrifice on the 33rd turn.

White: Jereon Piket (2635) – Black: Boris Avrukh (2588) [D97]
