Named after Swiss chess player Dr. Hans Grob
The Grob’s Attack is a chess opening characterized by the move 1.g4, also known as the “Grob’s Gambit”. This aggressive move is named after Swiss chess player Dr. Hans Grob, who is credited with popularizing the opening in the 20th century. The opening is a surprise weapon that is not often seen at high-level chess and is considered to be a unorthodox, aggressive and risky move.
The idea behind the Grob’s Attack is to quickly open up the g-file and attack Black’s king, as well as to gain space on the kingside. The move 1.g4 is also known as the “Grob’s Gambit” because it sacrifices a pawn for the initiative and control of the kingside. Black has a few options to reply to the Grob’s Attack such as 1…d5, which is considered to be the most solid move, but it allows White to gain a small advantage with 2.Bg2. Another option for Black is 1…e5, which is considered to be the most aggressive move, but it allows White to gain a big advantage with 2.h3.
