Four Knights Game: Spanish Variation, Bardeleben Variation

In the Four Knights Game: Spanish Variation, Bardeleben Variation, white starts with e4, aiming to control the center, gain space, and develop the f1 bishop. This pawn move also opens up lines for the queen and bishop, which can be useful in the middlegame.

Black plays e5 in response to e4 in order to gain control of the center and contest white's first move. This move also opens up lines for the queen and bishop, allowing them to become more active in the game. By pushing the pawn to e5, black also puts pressure on white's knight on f3, forcing it to either retreat or exchange itself for the black pawn. This can help black to control more space and develop their pieces more quickly in the opening.

White plays Nf3 after e4 e5 with the aim of controlling the center and developing a piece towards the center of the board. This move also opens up a potential attack on the black pawn on e5, which can be a target for white's pieces later on. The knight on f3 also helps to defend the pawn on e4, which is now a central target if black decides to advance their d-pawn. Moreover, by placing a knight on f3, white prepares moves like Ng5, which can put pressure on the black pawn structure and lead to tactical opportunities.

Additionally, by taking the knight on e5, Black eliminates the threat of a double attack on the bishop on c5 and the knight on f6 from the white queen. This move can also prepare for an attack on the white queen or the bishop on b5. However, by letting the d-pawn capture the knight that captures the Nxe5, it gives White the opportunity to regain the material balance.
