A very short miniature attributed to Gibaud and Frédéric Lazard is frequently reproduced in chess literature,[5][6] sometimes with the claim that it was the shortest game ever played between masters in a formal setting.[5] In its shortest and most commonly reproduced version, the game consists of four moves by each player. Black (Lazard) rapidly develops his king's knight to e3 after White (Gibaud) weakens the defense of the square.

In the final position White is unable to prevent the capture of his queen, because doing so would allow Black to force checkmate: 5. fxe3 Qh4+ 6. g3 Qxg3#.

The four-move, "formal" version of the game is not accepted as a real historical event.[6][8] Gibaud denied having ever lost a serious game in four moves, instead suggesting that he may have lost a casual skittles game against Lazard involving similar positional themes, albeit with more than four moves played. Gibaud also suggested that his game with Lazard might have been confused with a previously published "theoretical" miniature. Although the four-move version of the game is not accepted as historically accurate, it illustrates several principles of gameplay: the possibility for rapid development to cause serious problems for an opponent, the importance of not weakening the defense of critical squares, and the importance of defending a structural weakness on the kingside in the initial phase of the game (especially involving the f- and g- pawns), which if left unguarded may lead to a quick checkmate, akin to Fool's mate.
