 At the "Café", he was one of the leading players, but was known there only by the name of "Mulhouse" a nickname given to him, probably, by Saint-Amant.When St. Amant, began to frequent the "Café de la Régence", about the year 1823, he found "Mulhouse", capable of playing with La Bourdonnais at no greater odds than the Pawn and move, and fully equal to Boncourt and Mouret.Therefore, the young St. Amant took chess lessons from him.
