King's Indian Defense: Accelerated Averbakh Variation

When playing as White in chess, one of the most common opening moves is to advance the d-pawn two spaces to d4. This move aims to control the center of the board and get the pawn in a position where it can be later supported by other pieces. By establishing control over the center of the board early on, White can better dictate the pace and direction of the game. Moreover, it paves the way for future moves such as Bg5, which can put pressure on the black pawn structure and disrupt the development of Black's pieces.

When responding to White's opening move of d4, Black commonly counters with Nf6. This move serves to contest White's control over the center of the board by attacking the pawn on d4. Additionally, it brings the knight closer to the center and prepares for future development of the pieces. Another advantage of playing Nf6 in response to d4 is that it opens up various possibilities for attacking and controlling the center of the board, allowing Black to decide on their preferred playing style for the rest of the game.

After the initial moves of d4 and Nf6, White typically follows up with c4. This move strengthens the control over the center of the board and helps to limit the mobility of Black's knight on f6. By advancing the c-pawn, White can also open lines for the queen and bishop, enabling them to participate in the game more effectively. Furthermore, the pawn on c4 can become a valuable asset for attacking and exerting pressure on Black's position in the future. In sum, c4 is a strong and flexible move that sets the stage for a variety of strategic variations.

In the King's Indian Defense: Accelerated Averbakh Variation, Black often follows up the moves of d4 and Nf6 with g6. This move aims to prepare for the fianchetto of the dark-squared bishop, which can be a potent attacking piece in this opening. Moreover, g6 also assists in controlling the central squares, as it allows the knight to be repositioned to g7 and support the pawn structure. Another reason for playing g6 is to discourage the pawn advance of White's e4 pawn, which can create a strong pawn center. By playing g6 early, Black can limit White's attacking options and prepare for their own counterattacks.

Following the opening moves of d4, Nf6, g6, and c4, White will typically develop their knight to c3. By placing the knight on this square, White effectively supports their d4 pawn while simultaneously preparing to control the center of the board through further pawn advances such as e4. Moreover, Nc3 also assists in putting pressure on Black's position by attacking the b5 square and threatening to capture the knight on f6. Additionally, developing the knight to c3 enhances the coordination of White's pieces and sets up potential tactical possibilities in the middle game.

After playing the opening moves of d4, Nf6, g6, c4, and Nc3, Black typically responds with Bg7. This move completes the fianchetto of the dark-squared bishop, allowing it to exert pressure on the long diagonal and support the center of the board. By placing the bishop on g7, Black also prepares to castle their king, thereby protecting their monarch and developing their rook. Moreover, Bg7 enhances the coordination between Black's pieces and supports future attacks on White's position. Additionally, this move can provide Black with greater flexibility in selecting strategic plans for the upcoming middle game.

This move aims to seize greater control over the center of the board and gain more space for their pieces to maneuver. By advancing the pawn to e4, White also opens up lines for their queen, bishop and potentially their knight, strengthening the coordination of their pieces. Additionally, by playing e4, White aims to restrict Black's position and limit the mobility of their pieces. This move can lead to sharp and tactical positions in the middle game with potential for both sides to launch attacks against their opponent.

After the moves of d4, Nf6, g6, c4, Nc3 and Bg7, White will often play e4 as a way to gain more space and initiative in the center of the board. Black can respond by playing d6, moving the pawn to a more defensive position. By playing d6, Black safeguards their position by reinforcing the pawn on e5 and protecting their king from any potential attacks along the e-file. Additionally, d6 opens up possibilities for developing Black's light-squared bishop to d7 or c6 and potentially preparing for a pawn break in the center with moves like c5. This move can also help in gaining greater control over the center of the board and preparing for middle game plans.

After Black's move of d6, White commonly responds with Bg5, pinning Black's knight to their queen. This move pressures Black to decide how to respond - by either moving the knight or defending it with a pawn. If Black chooses to defend the knight, White can use a variety of strategies to maintain pressure and disrupt the opponent's position, such as exchanging the knight for Black's light-squared bishop. Additionally, Bg5 can be used as a prelude to the pawn advance of f4, exerting additional pressure on the center of the board. Ultimately, this move aims to limit Black's options and put White in a stronger position for the subsequent middle game.
