Grundy is known to have played in only one chess tournament of any note. However, his result in that tournament was outstanding. In the Fifth
American Chess Congress, held in
New York City in January 1880, Grundy tied for first with
George Henry Mackenzie, with each scoring 13½/18 in the double
round robin. At that tournament,
Preston Ware accused Grundy of reneging on a deal to draw the game, with Grundy instead trying to play for a win. A newspaper article contemporary to the event stated, "Ware's avowal of his right to sell a game in a tourney was a novelty in chess ethics ... Ware's veracity has not been questioned, only his obliquity of moral vision ..." ==Notable game==
