However in the game which follows, it is not one but both players who move the knight many times during the opening and the middle-stages of the game. The difference however is that Black wastes his moves in moving the knight while White’s knight is one of the strongest pieces on board.

White: Marco Manninen(2380)- Black: Alfred Felsberger(2395)European Championship, 1997
