King's Indian Defense: Averbakh Variation, Benoni Defense

Chess is a game of strategy and the opening move is crucial in determining the direction of the game. The move "d4" is a common opening move from white and is played to control the center of the board and to create space for the white pawn. By advancing the "d" pawn, white lays a foundation for further development of their pieces and can prevent black from increasing their control of the center. Playing "d4" also puts pressure on black's knight, which is why black often responds with "Nf6" to defend it.

Black's move "Nf6" is a natural response to white's "d4" move. It aims to control the center of the board and block white from advancing their pawns further. Additionally, "Nf6" puts pressure on white's pawn in the center and increases black's control of the board. The move also has tactical significance, as it opens up possibilities for black to later play moves like "d5" and "e5", which can create counterplay and put pressure on the white pieces.

White's move "c4" aims to continue controlling the center and initiating a battle for space on the board. By advancing the pawn two squares, white not only strengthens their grip on the center but also opens up the possibility of pushing the pawn to c5, which would further restrict black's movements. The move also lays the foundation for developing the white knight to c3 and the white bishop to b2. The pawn on c4 can also restrict black's pawn on d5, which is commonly played in response to "c4". In sum, "c4" is a solid move that gives white many options for developing their pieces and controlling the game.

In the King's Indian Defense: Averbakh Variation, Benoni Defense, black often responds to "c4" with "g6", intending to fianchetto their bishop on g7. This setup allows black to control the long diagonal and put pressure on white's center. Additionally, "g6" prepares for the move "d6" and enables the knight on f6 to move to g7, which helps protect the king. The move can also be used as part of the King's Indian Defense setup, where black aims for a counter-attack on the king's side. In sum, "g6" is a flexible and dynamic move that gives black many options for further development.

The move is flexible and allows white to decide which pawn to push - d4 or e4, according to the position on the board.

By playing "Bg7", black aims to fianchetto their bishop and control the important diagonal h1-a8. This setup suits well the King's Indian Defense variations where black aims for counterplay on the kingside. The bishop on g7 puts pressure on the pawn on d4 and restricts white's activity in the center. Additionally, "Bg7" enables black to castle kingside and improves the safety of the king's position. The move also prepares for the possible move "d6" followed by "e5", which can potentially open up lines for the attack.

White's move "Be2" is a logical move to complete the development of the light-squared bishop and support the e4 pawn. This move also clears the f1 square, allowing the king to castle kingside. The bishop on e2 also has an active role in the game, supporting the pawn push e4-e5, as well as protecting the pawn on d5, which black might eventually push.

In the King's Indian Defense: Averbakh Variation, Benoni Defense, castling kingside with "O-O" is a natural move for black. By castling, black neutralizes the threat to their king and connects the rooks, adding to the overall coordination of their forces. At the same time, "O-O" also opens up the possibility of utilizing the rook on f8 to support potential pawn advances in the center or on the kingside. Additionally, the move can add pressure on the g2 pawn and force white to make some concessions to limit black's attacking chances. In sum, "O-O" is an important step of development for the king and puts black in a good position for future plans and tactical operations.

In sum, "Bg5" is an active move that targets black's position, interferes with the development of black's pieces, and prepares for future tactical operations.

The move can also create opportunities for the queen and knight to be active and participate in the game. Moreover, "c5" can also help to gain space and free up the bishop on c8.
