Queen's Gambit Accepted: Old Variation, Novikov Gambit

In the Queen's Gambit Accepted: Old Variation, Novikov Gambit, the move 1. d4 is the starting move for White's main plan, which is to control the center of the board and restrict Black's mobility. By pushing the d-pawn two squares forward, White gains more control over the e5 square, which is an important central square. White can later develop the queen's bishop by playing Bf4, exerting more pressure on Black's center. Additionally, playing d4 allows White to potentially advance the pawn to d5, forcing Black to move their c7 pawn and potentially weakening their pawn structure.

In response to White's d4, Black plays d5 which is a solid move that aims to control the center of the board. This move also allows Black's c8 bishop to be developed. By playing d5, Black also puts pressure on White's central pawn and limits their options of advancing their pawn to d5. It's a safe move that avoids potential complications that may arise with unorthodox moves. Furthermore, it prepares the way for Black's pieces to be developed efficiently.

The move c4 by White is an attempt to control the center and create more space for their pieces. This move also supports White's d4 pawn, making it difficult for Black to challenge the d4 pawn with their own c5 move. By pushing the c-pawn, White aims to establish a strong pawn chain while also putting potential pressure on Black's d5 pawn. Additionally, c4 opens up potential diagonal lines for White's queen and bishop, giving more flexibility for potential future attacks or defenses.
