Gross attack after 1. g2 – g4
In Grob's Attack is an unconventional opening of the chess game . In the ECO codes , it is classified as "Irregular opening" under the key A00.
The basic position of Grob's attack arises after the king's knight pawn's double step :
1. g2-g4
history
This opening is named after the Swiss International Master Henry Grob (1904–1974), who analyzed the move in detail and played hundreds of correspondence chess games with this opening. In Grob's analysis in a newspaper column, he called the opening sting opening , a name that still enjoys individual use. Other older references used the name Ahlhausen opening after the Berlin player Carl Ahlhausen (1835-1892), one of the first 1. g4 players. Savielly Tartakower sometimes played the train in simultaneous performances , naming it Genoa or San Pier D'Arena opening , after the city and suburb of Genoa where he first played it. In Czechoslovakia the move 1. g2 – g4 was called the Frick's opening , and in other parts of the world it is called the Kolibri opening .
In a book by Grob, the attack g2 – g4 is still called "Genoese" or "Partie Ahlhausen" . In addition, Grob himself writes that he has largely researched this opening through the correspondence chess headquarters of the Neue Zürcher Zeitung (FSZ) and has come to the conclusion that White's plan of attack ( 1. g4, 2. Bg2, 3. c4 ) through Black ( 1. d7 – d5 2. e7 – e5 3. c7 – c6 ) can be refuted precisely.
Grob's attack is generally viewed as inferior and is usually not played at serious events, although International Master Michael Basman and Greek Grandmaster Spyridon Skembris play the move occasionally. The move, however, has a certain surprise effect; the average gamer mostly does not know how to refute him and is more likely to play arrogantly and make mistakes. Moreover, the ignorance of the theory of this move can break the repertoire of a seasoned opponent.

Gross attack after 1. g2 – g4 d7 – d5 2. Bf1 – g2 Bc8xg4 3. c2 – c4
Careless play by Black can lead to dangerous situations. Many of these lines are based on Black's answer 1.… d7 – d5 , which attacks the pawn with the queen's bishop. After 2. Bf1 – g2 Bc8xg4 !? White has after 3. c2 – c4 pressure game on the diagonal h1 – a8, combined with the possibility Qd1 – b3, after which White has the initiative and will win back his pawn (b7 or d5). White often falls behind in development, which is why Basman, for example, usually covers the pawn with 2. h2 – h3.
Because of the irregular pawn structure that White created by moving g2 – g4 and c2 – c4 so early on, any type of white castling results in a very sharp game.
Instead of the direct 2.… Bc8xg4 the covering of d5 with 2.… c7 – c6 is directed against all entanglements.
In view of the weakened field h4, Andrew David Martin recommends the immediate maneuver Ng8 – e7 – g6 after 1.… e7 – e5 2. h2 – h3. After 2. Bf1 – g2 he opens the h-file with 2.… h7 – h5. In order to avoid this, Henry Grob, the namesake of the opening, advocated 2. d2 – d3 in order to be able to advance on 2.… h7 – h5 with the pawn to g5.
If you don't want to sacrifice the g-pawn, you can use 1. g4 d5 2. g5 followed by h4, Bg2 and 0–0–0 into a sharp game.

Romford Counter Gambit
An interesting black answer is the aggressive Romford counter-gambit , which was discovered by the English player Nick Pelling around 1980 and named after his hometown : 1. g2 – g4 d7 – d5 2. Bf1 – g2 Bc8xg4 3. c2 – c4 d5 – d4! ? 4. Bg2xb7 Nb8 – d7 5. Bb7xa8 Qd8xa8 6. f2 – f3 d4 – d3 !. Due to the sacrifice of quality (rook versus bishop), black has free play of figures and a head start in development. With a structure like e7 – e6, Ng8 – f6, Nd7 – e5, Bf8 – c5 and 0–0, he has a clear strategic development plan, possibly combined with an attack on the king, while White is paralyzed on the back row.
Michael Basman also suggested a variation of the gambit after 3.… d5xc4.
