At the start of the game, white wants to control the center of the board. The move d4 helps accomplish this by gaining space and asserting control over the e5 square. Additionally, by opening up the possibility for the queen to move out, white can prepare for future attacks.

Black's move Nf6 is a common response to white's opening move d4. It mirrors white's control of the center of the board and asserts black's own presence on the board. Additionally, Nf6 prepares for future moves such as e6 and sets up the possibility for a defense based on Indian themes. Finally, it frees up the c8 bishop for potential deployment to the board.

White's move c4 is a natural response to black's Nf6. This move once again aims to control the center of the board and opens up the possibility for white's light-square bishop to participate in the game. Additionally, c4 prepares for the move d5, which would further enhance white's control of the board. The pawn on c4 also attacks black's pawn on d5 and creates potential for a future pawn break.

In the Nimzo-Indian Defense: Classical Variation, Belyavsky Gambit, Black's move e6 is a logical next step. This move aims to control the d5 square and prepare to develop the dark-square bishop. By placing a pawn on e6, Black also protects the knight on f6 and solidifies control over the center of the board. Additionally, e6 sets up the potential for the advance d5, which would further enhance Black's control of the board. Finally, e6 prepares for potential attacks on the king's position.

White's move Nc3 aims to continue the development of pieces and take control over more central squares. By placing a knight on c3, White sets up potential forks against Black's queen and bishop. Nc3 also prepares to move the d-pawn forward, potentially leading to future pawn exchanges or pawn breaks. Additionally, Nc3 prepares for the possibility of castling, which would further solidify White's position and defend against potential attacks. Finally, the knight on c3 can also play a role in potential attacks on Black's position.

Black's move Bb4 is a common response to White's move Nc3. By placing the bishop on b4, Black attacks White's knight and pressures the c3 square. Bb4 also pins the knight down and limits the mobility of White's pieces. Additionally, this move prepares for future moves such as Qa5 and places the bishop on a diagonal where it can apply pressure on White's position. Finally, Bb4 also hinders White's potential development of the light-square bishop.

In the Nimzo-Indian Defense: Classical Variation, Belyavsky Gambit, White's move Qc2 aims to support the knight on c3 and defend the pawn on d4. By placing the queen on c2, White also prepares for the possibility of a future move such as b3 or a3, which would further solidify White's position and actively prepare for potential attacks. Additionally, Qc2 vacates the d1 square, which can be used for the development of the light-square bishop. This move also sets up potential pins against Black's pieces on the b4-square and places the queen on a diagonal where it can potentially apply pressure on Black's position.

Black's move d5 is a common response to White's Qc2. This move aims to challenge White's control over the center of the board and creates potential for pawn exchanges. By pushing the pawn to d5, Black also prepares to develop the dark-square bishop. Additionally, d5 can potentially block White's queen from supporting the knight on c3, making it difficult for White to continue their development. Finally, d5 can also set up the possibility for counterattacks against White's position.

With the move cxd5, White captures Black's pawn on d5. This opens up the possibility for White's bishop to participate more actively in the game. Additionally, cxd5 takes control over the crucial d5 square and solidifies White's control over the center of the board. Capturing the pawn on d5 also creates potential for future pawn breaks and pawn exchanges. Finally, cxd5 can potentially block Black's queen from supporting the b4 bishop, making it difficult for Black to maintain the pin on White's knight.

In the Nimzo-Indian Defense: Classical Variation, Belyavsky Gambit, Black's move Qxd5 is a logical choice following White's move cxd5. By capturing White's pawn on d5 with the queen, Black not only removes a central pawn but also develops their queen early in the game. Qxd5 also creates potential for future pawn moves such as c5 or e5, which would give Black more space and further restrict White's position. Additionally, capturing the pawn with the queen can put pressure on White's position and potentially create threats against White's pieces. Finally, Qxd5 can potentially disrupt White's potential pawn breaks or exchanges.

With the move Nf3, White continues to develop their pieces and brings their knight into the game. By placing the knight on f3, White creates potential for future attacking moves and also prepares for the castle. Additionally, Nf3 can potentially attack Black's queen and put pressure on Black's position. This move also frees up the g1 square for the light-square bishop, which can be deployed onto an active diagonal. Finally, Nf3 potentially supports the pawn on e4, which would further enhance White's control over the center of the board.

In response to White's move Nf3, Black's move Qf5 aims to attack White's pawn on d3 and create potential for future threats. By placing the queen on f5, Black also maintains an active piece and threatens potential attacks on White's king. Additionally, Qf5 can potentially block White's bishop on c1 and restrict their pieces. Finally, by placing the queen on f5, Black prepares for potential moves such as Bh3, which would further increase the pressure on White's position.

In the Nimzo-Indian Defense: Classical Variation, Belyavsky Gambit, White's move Qd1 aims to defend the pawn on d3 and vacate the d1 square for the development of the light-square bishop. Additionally, Qd1 prepares for the possibility of a future castle, which would further defend White's position and free up potential attacking pieces. By moving the queen to d1, White also places potential pressure on Black's queen on f5 and threatens potential attacks on Black's king. Finally, Qd1 also potentially takes control over the d-file, giving White potential control over more central squares.

In response to White's move Qd1, Black's move e5 aims to challenge White's control over central squares and gain more space on the board. By advancing the pawn to e5, Black intends to open up potential lines of attack against White's position and potentially put pressure on White's position. Additionally, e5 prepares for the development of the light-square bishop and frees up the d8 square for the rook. This move also potentially blocks White's bishop on c1, restricting their pieces and limiting their mobility. Finally, e5 can be used as a potential pawn break in the center of the board, creating potential for pawn exchanges and further aggression.
