Gilles Andruet (born 30 March 1958, Versailles – 22 August 1995 near Saulx-les-Chartreux, Essonne) was a French chess player, an International Master and a former national champion.

[3] During the 1989 Championship, Andruet was involved in a violent altercation with Jean-Luc Seret and subsequently withdrew from the tournament despite the fact that he was in the lead after 10 of 14 rounds.

Starting in 1993, he regularly played backgammon and blackjack in casinos and although he initially won significant amounts of money, he eventually became a pathological gambler riddled with debt.

The investigation focused on Joseph Liany and his son Franck who had presumably helped Andruet cash a check of 398,000 French francs.
