Queen's Gambit Declined: Chigorin Defense, Modern Gambit

At the start of a chess game, white's primary objective is to control the center of the board. This is achieved by moving the pawn on d2 to d4, placing pressure on black's pawn on d5. This move allows white to gain more space on the board and creates opportunities for the development of their pieces. Additionally, this move prepares for the pawn on c2 to move forward in the next few moves. By controlling the center of the board, white can build a strong and flexible position, allowing for a variety of strategic options moving forward.

In response to white's opening move, black plays d5 to control the center of the board and challenge white's pawn on d4. By advancing their own pawn to d5, black ensures they have equal access to the center as white does. This move also potentially frees up the bishop on c8 and the queen on d8 for future development. Additionally, playing d5 also creates a barrier that prevents white's pieces from moving into black's territory. In sum, d5 is a strong response that sets up the game for dynamic and interesting play.

White's move of c4 after Black plays d5 is known as the queen's pawn opening. With this move, white aims to gain more control of the center board and put pressure on Black's position. By pushing their c-pawn, white gains more space on both sides of the board and challenges Black's pawn on d5. This move also prepares for the development of the queen's bishop to c4 and supports the possibility of a future pawn exchange. In sum, c4 is a strong move that sets up White for a flexible and dynamic opening strategy.

In the Queen's Gambit Declined: Chigorin Defense, Modern Gambit, Black responds to White's move of c4 with Nc6. By placing their knight in the center, Black looks to reinforce control over the central squares and attack White's pawn on d4. This move also prepares for the possibility of exchanging pawns on d4 and establishes a strong foothold in the center of the board. Furthermore, this move allows Black to avoid the more common moves of e6 or c6 and can lead to unpredictable and unexplored territories of the game.

In response to Black's move of Nc6, White plays Nc3, developing their knight to a good centralized position. With this move, White prepares for the possibility of exchanging knights and challenging Black's control of the center. By placing their knight on a more active square, White also creates some potential threat to Black's queen's knight and maintains some pressure on the center of the board. In some variations, the knight on c3 can also potentially support an upcoming e4 pawn push or take control of the b5 square, or even go to a3 to pressure Black's pawn on b4 if their queen's knight moves. In sum, Nc3 is a flexible and strong move that creates chances for White to build a strategic advantage.

In response to White's move of Nc3, Black plays the move dxc4, which aims to disrupt White's central pawn structure and gain control of the center board. By exchanging pawns on c4, Black also frees up their knight on c6 and creates some pressure on White's d4 pawn. This move opens up new tactical possibilities for Black, such as attacking White's pawn with their queen if White tries to defend it with their knight. This move can also sometimes lead to the creation of a passed pawn on c4 for Black, which can become a strong asset in the endgame. In sum, dxc4 is a dynamic and aggressive move that creates interesting and complex strategic possibilities for both players.

In the Queen's Gambit Declined: Chigorin Defense, Modern Gambit, White responds to Black's move of dxc4 with Nf3. This move develops a knight, puts pressure on Black's pawn on e5, and prepares for the eventual development of the queen's bishop to c4. By placing the knight on f3, White's pieces can work together to control the center of the board while also attacking Black's pieces. This move also allows White to castle, which can be important for the safety of their king. Additionally, Nf3 avoids blocking the c1 bishop, which can still play an important role in the game. In sum, Nf3 is a flexible move that strengthens White's position and prepares for future tactical possibilities.

In response to White's move of Nf3, Black plays Nf6, which develops a knight to a good central square while also threatening to attack White's pawn on d4. This move also allows Black to prepare for the eventual development of their king's bishop. By controlling the e4 square, Black creates some pressure on White's position and increases their own flexibility in future moves. Additionally, playing Nf6 can tempt White into playing e4, which can open up lines for Black's pieces and create tactical opportunities. In sum, Nf6 is an active move that sets up Black for a solid and flexible position in the game.
