Alekhine Defense: Exchange Variation

Alekhine Defense: Exchange Variation is an opening that usually starts with the move e4 by white. The first move e4 establishes control over the center, which is a fundamental principle of chess opening strategy. It also allows the king's pawn to develop and frees the queen and bishop. By occupying the center, white aims to create a strong position and control the board's crucial squares. However, this opening is known for its tricky moves, making it a popular choice among experienced players.

Playing Nf6 after e4 is an integral part of many Black defenses, including the Alekhine Defense: Exchange Variation. This move attacks the e4 pawn and puts pressure on the center. It also allows the knight to develop to a good central position and puts pressure on the pawn chain. Additionally, Nf6 prepares Black's king to castle and protects the g7 square, which can be vulnerable in many openings. In sum, Nf6 is a strong and popular response to e4.

Playing e5 after Nf6 by Black is a common response by White in the Alekhine Defense. This move, like e4 earlier, aims to control the center of the board. By advancing the pawn to e5, white increases the pressure on Black's knight and aims to gain more space in the center. It also opens up possibilities for the queen and light-square bishop to come into the game. However, playing e5 too soon can also create weaknesses that Black can exploit. Hence, White must be cautious and try to maintain a balance between aggression and calculation.

Moreover, d4 leads to a pawn chain with c4, which strengthens White's position and restricts Black's options. In sum, d4 puts significant pressure on Black's position and sets the stage for a strategic battle.
