Question: can a knight jump over its own pieces

Answer: Yes, The knight move is unusual among chess pieces. It moves to a square that is two squares away horizontally and one square vertically, or two squares vertically and one square horizontally. The complete move therefore looks like the letter ``L''. Unlike all other standard chess pieces, the knight can ``jump over'' all other pieces (of either color) to its destination square. It captures an enemy piece by replacing it on its square. The knight's ability to ``jump over'' other pieces means it tends to be at its most powerful in closed positions , in contrast to a bishop. The knight moves alternately to light and dark squares.
