Slav Defense: Alekhine Variation

The move d4 is a central pawn move taking control of squares e5 and c5. This move is crucial for White as it leads to a significant territorial advantage in the center. By placing the pawn on d4, White hopes to restrict Black's movements and put pressure on the d5-pawn. Additionally, this move opens up diagonals for the bishop and queen to attack Black's position. In sum, it is a strong opening move that sets the stage for a solid and aggressive game.

The move d5 by Black does two things. Firstly, it challenges White's control of the center by putting pressure on the d4-pawn. Secondly, it prepares for Black's own central advance by supporting the pawn on c6. This move is a strong response to White's d4 as it allows Black to establish a solid position in the center. However, it also limits Black's bishop on c8 from being developed. Nonetheless, overall, d5 is a good move for Black in this opening and leads to interesting and dynamic positions.

The move c4 by White is known as the Queen's Gambit and is a common and strong response to Black's d5. By playing c4, White gains control of the important central square d5 and forces Black to make a decision about their pawn structure. If Black captures the pawn on c4, White can recapture with the queen, gaining even more control of the center. If Black chooses not to capture, then White has maintained a strong pawn chain in the center and can later push the pawn to d5 or maneuver their pieces for a stronger position. In sum, c4 is a strong and aggressive move that puts pressure on Black while enhancing White's chances for success.
