The move theory warns against, played on purpose. One thrust and the kingside is loosened for the rest of the game — no take-backs, no repairs. What it buys: the g4-g5 space grab, the Bg2 diagonal opened with the g-pawn already out of its way, and an opponent staring at a position no repertoire prepared them for. The Grob gambit follows when Black grabs the pawn: the long-diagonal bishop and the queen coordinate against b7 and the loose pawn, and careless collectors lose material by move six. Sound it is not. Toothless it is not either."]]

Grob's Attack — 1.g4 — is the most notorious first move in chess, and its notoriety is well earned in both directions. Objectively it is the weakest opening carrying a serious name: the kingside is loosened permanently for modest gain, and every reference work says so. Practically it is a minefield with a curator — the Swiss master it is named for played it in thousands of correspondence games and won constantly, and its modern devotees keep demonstrating that "refuted" and "safe to face unprepared" are different claims entirely. The gap between those two truths is where the Grob lives.
