following his u.s. title in 1954, bisguier regularly returned to compete for the national championship, but was never able to repeat his success. the late 1950s saw the sensational rise of bobby fischer, who swept the eight u.s. championship tournaments that he contested. bisguier and fischer were tied for first place going into the last round of the 1962–1963 event, and they still had to face each other. bisguier had a promising position but made a mistake, which fischer punished spectacularly, allowing fischer to take the game and the title. fischer scored 8/11, with bisguier a point back in clear second place. bisguier also served as a second to fischer at several international events.
