Queen's Gambit Declined: Lasker Defense, Teichmann Variation

In the Queen's Gambit Declined: Lasker Defense, Teichmann Variation, White opens with d4 to gain control over the center of the board. By placing this pawn in the middle, White can attack Black's pieces and restrict their mobility from both sides. Moreover, this move aims to create a pawn chain that supports White's other pieces, such as the knights and bishops, to develop easily. With d4, White can initiate the famous Queen's Gambit Declined line and put pressure on Black's defense.

Black plays Nf6 in response to White's d4 to contest control of the center from the first move. This move sets up potential counterattacks on White's pawn chain and allows development of the knight to establish a positional foothold on the board. Moreover, Nf6 prepares Black's pawn to advance to d5, further undermining White's pawns. It can also facilitate the development of the light-squared bishop to either g7 or e7, depending on how the game progresses. In sum, Nf6 is a flexible move that gives Black many options for their play.

After the opening move d4, White follows up with c4 to put further pressure on Black's position. By controlling the center, White aims to limit Black's ability to maneuver their pieces, and gain space advantage. c4 also prepares to develop the knight to c3, solidifying the pawn chain and providing protection for d4 pawn. This move is also known as the Queen's Pawn Opening, and it invites Black to respond with e6, a move that is often played in the Queen's Gambit Declined. By playing c4, White sets up an important positional foundation for their pieces that may lead to various tactical possibilities later in the game.

In the Queen's Gambit Declined: Lasker Defense, Teichmann Variation, Black plays e6 to establish control over the d5 square, preventing White from easily advancing their pawn to that square. This move prepares Black to set up a pawn chain with the pawns on d5 and e6, providing a solid foundation for the rest of their pieces. Additionally, e6 opens up the possibility of developing the light-squared bishop to f5 or g4, from where it can put pressure on White's position. Black's e6 move also lays the groundwork for a possible pawn break with d5, freeing up their pieces and challenging White's pawn structure.

After the opening moves d4 and c4, White continues with Nf3 to develop their pieces and dominate the center of the board. Nf3 prepares the way for the light-squared bishop to emerge from behind the pawn chain, should Black's knight later move off the f6 square. It also makes attacking Black's position more challenging by reinforcing the pawn on d4 and creating additional control over the e5 square. Finally, Nf3 fits well with the plans to castle kingside, putting the knight in a more defensive position and providing support to the king. In sum, Nf3 is an important piece development move in the Queen's Gambit Declined, establishing White's dominance over the center of the board and setting up potential future tactics.

In response to White's Nf3, Black plays d5 to challenge White's central pawn control and to open up lines for their pieces. This move aims to undermine the pawn structure of White and takes control of the crucial square d4. By advancing the d-pawn, Black gains momentum and threatens to trade pawns, freeing up their pieces' mobility. The move also creates the possibility of channeling the bishop to c5, putting immediate pressure on the White's pawn structure. In sum, d5 is a critical move that allows Black to play actively and attack White's position.

This move attacks Black's pawn on d5, which is currently undefended, and places pressure on Black to defend it or risk losing a pawn. At the same time, Nc3 develops a piece towards the center, preparing the way for White to castle kingside and potentially launch an attack against Black's position. This move also frees up the b1 knight and allows it to develop towards c3, eventually creating a strong pawn structure on d4 and c3, which are difficult for Black to dislodge. In sum, Nc3 plays an important role in developing White's position and solidifying their pawn chain in the center.

After the moves 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3, Black plays Be7 to develop their light-squared bishop and provide additional defense to their king. By retreating to e7 rather than exchanging on c3, Black avoids doubling White's pawns and maintains pressure on the pawn on d4. Moreover, the bishop on e7 pointing towards the center of the board, with the potential to move to f6 and challenge White's pawn structure. Be7 also prepares for a potential kingside castling, completing Black's rook development. In sum, Be7 is a flexible move that offers Black more options and prepares for further developments in the game.

After Nc3 and Be7, White plays Bg5 in the Queen's Gambit Declined to put pressure on Black's knight on f6 and attack the bishop on e7. This move pins the knight and potentially creates an opportunity for White to exchange light-squared bishops in an effort to undermine Black's pawn structure. Bg5 also prevents Black from castling kingside, as moving the knight or the bishop from f6 would leave their king exposed to a potential attack by White's pawns and pieces. In sum, Bg5 is a move that creates tactical possibilities for White and forces Black to make decisions about their development and pawn structure.

In the Queen's Gambit Declined: Lasker Defense, Teichmann Variation, Black plays h6 after White's Bg5 to force White's bishop to retreat and prevent potential checks on g5 in the future. This move also prepares for Black to eventually advance the g-pawn, creating a pawn chain and potentially attacking the White's bishop that is now on h4. h6 also has a prophylactic character, preventing a potential pin of the knight on f6 by White's queen or bishop in the future. In sum, h6 is a flexible move that creates more options for Black and limits the tactical possibilities for White.

In response to Black's h6, White plays Bh4 to retreat the bishop to a safe position and preserve its potential future use. This move also allows the bishop to maintain pressure on the knight on f6, making it more difficult for Black to develop their pieces. Moreover, Bh4 also sets up the possibility of recapturing on f6 with the bishop instead of the pawn, further maintaining White's pawn structure. Additionally, potential deployment of White's g-pawn to open up the h-file for an attack on Black's castled position may be contemplated when the opportunity arises. In sum, Bh4 is a flexible move, aiming to maintain White's options and limit Black's freedom of movement.

This move also allows the rook on f8 to potentially become more active and participate in a future pawn break or an attack on the weakened pawn on d5. Additionally, castling kingside allows Black to develop the knight on f6, which was previously pinned by White's bishop on g5, to a more active position. Finally, O-O also prepares for Black to double their rooks on the e-file, potentially adding pressure on White's position. In sum, O-O is a natural move that improves Black's position and enables further development.

This move also allows for the development of White's dark-squared bishop to e2, where it can challenge Black's pawn structure. Moreover, e3 paves the way for potential f2-f4 pawn break initiatives, with the aim of attacking Black's position and opening up lines of attack against the King. Additionally, e3 forms the basis of a solid defensive formation, preparing White to resist any counterattacks launched by Black. In sum, e3 is a flexible move that improves White's position and lays the groundwork for further tactical play.

This move leaves Black with an isolated pawn, making it more difficult to defend and create counterplay in the future. Additionally, Bxe7 opens up the possibility for White to potentially bring their queen to e2 or f3 with the aim of attacking Black's weakened pawn on d5. Moreover, an open file to place the rook on e1, pinning the d-pawn by Black, may also be a possibility.
