The Knight has a distinctive movement pattern. It is described as an "L-shaped" pattern. In simple terms, the Knight combines the Rook Chess move and the Bishop Chess move. The Rook travels in a straight line and the Bishop travels diagonally. The Knight takes a short cut between the two and accomplishes more than either of them.
Moving in its pattern, the Knight has distinct advantages. There are only 9 moves it can make from its epicenter. The Knight can leap over other pieces. He is the only piece on the chess board that does not have a straight line of sight path that it takes.
The Knight is able to get to other Chess pieces that are totally surrounded and take them out before these pieces are mobile. This makes the Knight a black OPS in your chess board game. The rest of the chess pieces cannot follow him. This is a warning to be careful in how you use this piece. Do not be too careless in using it; he may be the only one that saves the game.
Knights cannot strike at opponents far away but they can creep up on them slowly and craftily. Like the Pawn and the King, the Knight is limited in its ability to move and attack. Realize that you need to learn to use this to your advantage to keep the game progressing toward checkmating the King.
Some things never change; The Knight may capture a piece by landing on the opponents square. This is the way that all pieces are attacked, and it is no different with the Knight. He can attack and capture as many pieces as any other piece captures.
In conclusion, the Knight is essentially the black OPS in your operation (chess game strategy). Do not foolishly spend any of your pieces. This is a game to be thought out carefully, using wisdom and chess playing experience to become the greatest competitor and chess player ever. Go Play Chess!
