Grünfeld Defense: Exchange Variation, Simagin's Lesser Variation

Chess players may wonder why white often plays d4 in the opening, such as in the Grünfeld Defense. The answer is simple: d4 is a central pawn move that takes control of important squares in the center of the board. It also allows white to potentially develop their pieces and gain more space on the board. However, playing d4 can sometimes lead to a more closed game, limiting the mobility of the pieces. Nonetheless, the move d4 remains a key strategy for white in many openings.

When Black plays Nf6 in response to 1. d4, they are aiming to control the center of the board through indirect means. By attacking white's pawn on d4, Black hopes to force white to spend time defending it rather than making further advances. Additionally, playing Nf6 allows Black to develop their knight and prepare for future moves. This opening move is a common and effective response against 1. d4 and can lead to a variety of openings and defenses depending on white's next move.

White's move c4 in response to 1. d4 Nf6 aims to exert control over the board's center and create more space for their pieces. The move also allows White to potentially develop their queen's bishop and knight to c3 or f3. By controlling more squares in the center of the board, White can limit Black's mobility and set up more opportunities for threatening moves. The move c4 is usually followed by Nc3, which is a common pattern in many openings for White.

In the Grünfeld Defense: Exchange Variation, Simagin's Lesser Variation, Black's move g6 is a common response to White's move c4. It allows Black to develop their bishop and control the important square d5. Playing g6 also prepares for future moves involving fianchettoing the bishop to g7, which can be a strong defensive position for Black. By not immediately playing d5, Black aims to discourage and delay White's pawn advances in the center of the board. The move g6 usually leads to a hypermodern opening in which Black plays for control of the center from the sidelines.

When facing the Grünfeld Defense and having played 1. d4 Nf6 2. c4 g6, White's move Nc3 is a natural development move, aiming to get a piece closer to the center of the board and allowing for the possibility of a future pawn push to d5. Nc3 also indirectly applies pressure on Black's central pawn on d5, making it more challenging for Black to advance it. Additionally, the knight on c3 can potentially support an attack on the queenside, or jump to e4, which can pressure Black's defenses. In sum, Nc3 is a flexible move that prepares for various future options while still developing a piece.

In response to 1. d4 Nf6 2. c4 g6 3. Nc3, Black's move d5 aims to challenge White's control over the center of the board.

The move also allows Black to gain space and potentially develop their pieces more effectively. Playing d5 can also force an exchange in the center of the board, leading to a more open game. In sum, d5 is a common and strong move in various openings, including the Grünfeld Defense.

In the Grünfeld Defense: Exchange Variation, Simagin's Lesser Variation, White's move cxd5 is a typical response to Black's move d5. It captures the pawn on d5, exchanges a central pawn, and strengthens White's control over the center of the board. The move also opens the c-file, allowing for the possibility of future rook maneuvering. However, playing cxd5 also gives Black more space for their pieces and the possibility of developing their bishop on g7.
