In blitz the knight is stronger than the bishop - Vlastinil Hort
The Knights represented the cavalry on the chessboard. The distinctive move is unchanged since the piece was invented in India during the 6th century. The Knight like the cavalry doesn't charge directly at the enemy. As it moves in it veers to one side in an effort to outflank the opposing forces. This is where the Knight's movement comes from. Along with its ability to jump all blockades, with its distinctive movement, it is pretty hard to imagine chess without the Knight. Maybe that's why its movement was never changed. Don't mess with perfection.
