Queen's Gambit Declined: Lasker Defense, Russian Variation

One of the classic openings for White in chess is to start with 1. d4. The pawn move is not only a strong central occupation but also allows White to potentially gain control over the d5 square. With a pawn on d4, White can also develop the knight on c3 and prepare for the early exchange on c4. The idea is to put pressure on Black's pawn structure and create imbalances on the board. By advancing the d-pawn, White also gains space and prepares the way for their pieces to move into the center of the board.

In response to 1. d4 from White, Black's natural move is to play d5. By doing so, Black also gains control over the center of the board and challenges White's pawn on d4. Moreover, Black's pawn on d5 allows the knight on f6 to become more active and puts pressure on White's pawn structure. By pushing this pawn, Black aims to control more space and eventually launch a counterattack against White's position. The move d5 is crucial in many opening systems and is one of the most common responses to 1. d4.

One of White's most natural and aggressive moves after 1. d4 d5 is to play c4. By advancing the pawn to c4, White aims to gain control over the center of the board and create a strong pawn duo (d4 and c4) that restricts Black's pieces. Moreover, the move c4 develops the queen's knight on b1 and prepares for the pawn exchange on d5. By capturing on d5 with cxd5, White can create an isolated pawn on d5 on Black's side, which is often a positional weakness in many chess games. In sum, c4 is a strong move that forms the basis of many well-known opening systems, like the Queen's Gambit.

In the Queen's Gambit Declined: Lasker Defense, Russian Variation, Black's natural reply to 2. c4 from White is to play e6. By playing e6, Black aims to control the vital d5 square and deter White's pawn from advancing further. Moreover, e6 prepares for the development of Black's light-squared bishop on f8 and keeps the pawn structure compact and solid. Black's pawn on e6 also provides more flexibility in the position and allows the knight on f6 to move to the center of the board via d7 or g4 if needed. In sum, the move e6 is a common and practical response to 2. c4 in the Queen's Gambit Declined opening.

In the sequence 1. d4 d5 2. c4 e6, White's natural move is to play Nc3. By developing the knight to c3, White gains control over the central squares and prepares for further attacks on Black's position. Moreover, the knight on c3 supports the pawn on d4 and encourages Black to capture the pawn with their c6 pawn, which would lead to an isolated d-pawn on Black's side. In some suggested lines, the knight on c3 can also prepare for the move e4, which would increase the pressure on Black's position and open up the position for White's pieces. In sum, Nc3 is a standard and strong move in the Queen's Gambit family of openings.

In the sequence 1. d4 d5 2. c4 e6 3. Nc3, Black's natural move is to play Nf6. By developing the knight to f6, Black gains control over the central squares and prepares to castle kingside. The knight also puts pressure on White's pawn on d4 and hinders White's plans of playing e4. Moreover, the knight on f6 supports Black's pawn on e6 and prevents White's bishop on g5 from pinning the knight on f6 via h4. In some suggested lines, the knight on f6 can later support the pawn advance of dxc4 followed by the queen move to a5 which aims to challenge the positioning of White's pieces. In sum, Nf6 is a solid and flexible move that is part of many different variations within the Queen's Gambit family of openings.

In the Queen's Gambit Declined: Lasker Defense, Russian Variation, after the moves 1. d4 d5 2. c4 e6 3. Nc3 Nf6, White's natural move is to play Bg5. By developing the bishop to g5, White pins Black's knight on f6 and discourages the pawn advance to g6, which would release the pin. If Black decides to capture the bishop with the knight, White can recapture with the queen and put pressure on Black's pawn structure. Moreover, the bishop on g5 increases the control over the central squares and prepares the way for the castle on kingside. In some suggested lines, the bishop on g5 can also support the pawn advance to h4, which can weaken Black's kingside structure and gain space on the board. In sum, Bg5 is a common and logical move in the Queen's Gambit decline opening and requires Black's careful planning to respond.

The bishop on e7 also guards the important d6 square and allows the queen to move towards the c8-h3 diagonal, which can create some counterplay against White's king. Moreover, the move Be7 releases the pin on the knight on f6 and prepares the capture on d4 followed by the pawn advance to c5, which aims to create threats in the center and challenge White's pawns. In some suggested lines, Be7 can also prepare for the pawn advance to f6, which further protects the king and gains space on the board. In sum, Be7 is a flexible and solid move in the Queen's Gambit decline opening and prepares the way for Black's pieces to become more active.

The move e3 also prepares for the development of the light-squared bishop on f1 and restricts the mobility of Black's pieces on the kingside. Moreover, the pawn on e3 prevents possible future tactics by Black that would involve the discovery of the queen on the bishop on g5, which can become an issue for White's position if not addressed. In some suggested lines, the move e3 can also prepare for the pawn advance to d5, which can lead to a central pawn break and create new opportunities for White's pieces. In sum, e3 is a strong and flexible move that solidifies White's position and prepares for future attacks or defenses.
