On 7.dxe5 Qxd1 8.Rxd1 fxe5, White cannot take the e5-pawn with the knight because the knight is pinned by the bishop. Multiple trades have occurred, however, bringing the position closer to an endgame, which is beneficial for White, who has the better pawn structure.
The King's Knight Opening is a chess opening consisting of the moves: . 1. e4 e5 2. Nf3. White's second move attacks the e-pawn. Black usually defends this with 2...Nc6, which leads to several named openings.
At the most basic level, White's third move attacks the knight that defends the e5-pawn from the attack by the f3-knight. White's apparent threat to win Black's e-pawn with 4.Bxc6 dxc6 5.Nxe5 is illusory—Black can respond 5...Qd4, forking the knight and e4-pawn, winning back the material with a good position. [ 7 ]
In chess, a relative value (or point value) is a standard value conventionally assigned to each piece. Piece valuations have no role in the rules of chess but are useful as an aid to evaluating a position. The best-known system assigns 1 point to a pawn, 3 points to a knight or bishop, 5 points to a rook and 9 points to a queen. Valuation ...

Consequently, a knight alternates between light and dark squares with each move. [2] When moving, the knight can jump over pieces to reach its destination. [a] [b] [4] Knights capture in the same way, replacing the enemy piece on the square and removing it from the board. A knight can have up to eight available moves at once.
In particular, if the pawn is on its sixth rank and is a bishop pawn or rook pawn, and the bishop does not control the pawn's promotion square, the position is a draw. [55] See Wrong bishop . A rook versus a minor piece: normally a draw but in some cases the rook wins, see pawnless chess endgame .
A rule of thumb (with exceptions) is: if the king on the side without the pawn can reach the queening square of the pawn, the game is a draw; otherwise it is a win for the opponent (except with a rook pawn, i.e. a- or h-file). [12] The side with the pawn can cut off the opposing king or strive for the Lucena position, which is a win.
