This is David Sullivan with the knight and how to use it.
This is a white knight. You begin the game with two white knights. A knight moves in an L-shape like from here D4 goes one, two and then one. Notice the letter L, but this L can be backwards, one,two one in this direction or it can be kind of sideways and upside down. The knight always goes one two and then it turns, one, two and then it turns, one two and then it turns.
The knight, for instance, to get from F1 on the first rank all the way over here in four moves, you could go up two and turn, up two and turn, up two and turn, and then it could go to the side two and turn to reach the other side of the board.
The knight has one special power. It can jump. So even if the knight were, say, surrounded by these black pawns and kind of used as targets here the knight can jump over the pawns like it could go jump one two, jumping over this pawn on E4 and then turns landing on F5.
From F5 it could go one two, jumping over these two. squares landing on the E3 square. Whatever you land on in chess you capture. From E3 the knight could go up two one to the side landing on the pawn in D5, or it could go to the side too jumping over these two pawns landing on the pawn on C4.
Move, move, turn; move, move, turn. So move, move, turn, we capture the pawn. Move, move turn, jump, jumping over the pawn and capture the pawn. Jumping over the pawn, jumping over the E3 square landing on E4 capturing it. Jump, jump, capture; jump, jump, capture; jump, jump, capture; and then finally jump, jump, capture.
At the beginning of the game and the knights who cam jump over of chess the only pieces that can move are the pawns who block everybody else and the knights who can jump over the pawns.
