Grob Opening: 3 quick facts

  • The Grob Opening, also known as Grob’s Attack, is named after Swiss chess player Henri Grob. It’s an unconventional flank opening, meaning it begins with a flank (side) pawn move instead of a center pawn move.
  • This opening is considered unsound and is often regarded as one of the worst possible starting moves for White. It breaks common opening principles by voluntarily opening up the kingside on move 1, which reduces White’s king safety and ability to castle kingside.
  • It can occasionally work due to its shock value, as opponents may underestimate it and play carelessly, but it relies heavily on them falling victim to traps. Because of this, the Grob is not recommended for beginners or serious tournament play.
