The Anti-Borg Opening arises after 1.h4 and falls under ECO code A00. Also known as the Desprez Opening or Kádas Opening, this is an uncommon kingside flank move that contributes nothing to development, concedes central control, and compromises the kingside pawn structure. While the rook gains access to the h-file, it rarely finds a useful post on h3. The move arguably weakens White's position overall, since kingside castling becomes unappealing. Given these drawbacks, it almost never appears in serious classical play, though it can serve as a surprise weapon to unsettle an opponent. Top players such as Magnus Carlsen and Hikaru Nakamura have employed it in blitz games, and Carlsen notably used it in the November 2023 Titled Tuesday online tournament, successfully defeating several strong grandmasters including Alireza Firouzja. With 5.2 million Lichess games across all rating levels, it is a well-established opening.
