g4

-1.48

In the Grob Opening: London Defense, white initiates the game by playing g4 which is a highly aggressive move. This move is intended to control the center of the board by putting pressure on the black pawn situated on e5.

e5

-0.66

When Black plays e5 in response to 1. g4, they are aiming to contest control over the central squares of the board. The e5 pawn advances and attacks the pawn on g4, discouraging White from advancing further. Additionally, it opens up lines for the Black queen and bishop to become more active, which can help Black gain an early advantage in the game. However, if Black isn't careful, their pawn structure could become weak and vulnerable to White's attacking pieces. Consequently, precision and sound defensive chess is essential for Black in the early stages of the game.

h3

-1.6

In this position, White's move of h3 after Black's e5 serves to prepare for the potential development of the light-squared bishop to g5. By putting a stop to any potential bishop pins or checks, White aims to maintain control over the center of the board. Additionally, h3 allows White's king to be safer on the h2-square, should the need arise. However, the pawn move h3 also comes at the cost of losing a tempo which could be used to develop other pieces. As such, the move should only be played when it serves a clear strategic purpose in the game.

Nc6

-0.91

In the Grob Opening: London Defense, Black's move of Nc6 aims to take advantage of White's slower development of their crucial pieces. By developing their knight to a central square, Black not only puts pressure on the pawn on e5 but also lays the groundwork for establishing a strong position in the center of the board. This is especially important as the opening progresses and the players begin jostling for control of the key squares. Moreover, Nc6 can allow Black to prepare the move d5, which, if timed well, can potentially disrupt White's pawn structure and create new lines of attack. However, by moving the knight out so early in the game, Black risks overextending their forces and leaving their king vulnerable to attack.

How to play the Grob Opening: London Defense

Next, they move h3 which prevents the black bishop from moving to g4 and attacking the pawn on f3.

Black will most likely reply with e5 (putting pressure on White's pawn) allowing the knight to go to c6 and block the advance of White's pawn.

White must be cautious with their moves as the effectiveness of this opening depends heavily on taking the opponent by surprise and maintaining control of the center.

How to counter the Grob Opening: London Defense

The best response is to quickly control the center by attacking White’s pawn with e5.

Black should then develop their pieces, put their king in safety and aim to control the center of the board.

Finally, increasing pressure on the central pawns and opening lines for mobility will maximize Black's chances for victory.

Pawn structure in the Grob Opening: London Defense

Grob Opening: London Defense has a unique pawn structure that can have both benefits and drawbacks depending on how the game unfolds.

The move g4-h3 creates a pawn trio of pawns on the third rank (g/h/f), which can provide control over the central squares and discourage Black's pawn advances.

However, blocking the f-pawn limits the possible scope of White's light-squared bishop and creates a potential weakness near the king.

Black can exploit this weakness by attacking the weakened kingside.

If the attack is not prepared, White could be in danger and end up facing a difficult position.
