Donald Byrne was one of the leading American chess masters at the time of this game. He won the 1953 U.S. Open Championship, and later represented the United States in the 1962, 1964, and 1968 Chess Olympiads. He became an International Master in 1962, and probably would have risen further if not for ill health. Robert "Bobby" Fischer was at this time a promising junior facing one of his first real tests against master level opposition. His overall performance in the tournament was lukewarm, but later he had a meteoric rise, winning the 1957 U.S. Open on tiebreaks, winning the 1957–58 U.S. Championship, qualifying for the Candidates Tournament and becoming in 1958 the world's youngest grandmaster at the age of 15. He won the world championship in 1972, and is considered to be one of the greatest chess players of all time. In this game, Fischer demonstrates noteworthy innovation and improvisation. Byrne, after a standard opening, makes a seemingly minor mistake on move 11, losing a tempo by moving the same piece twice. Fischer pounces with brilliant sacrificial play, culminating in a queen sacrifice on move 17. Byrne the queen, but Fischer gets far too much for it – a rook, two bishops, and a pawn. At the end, Fischer's pieces coordinate to checkmate, while Byrne's queen sits useless on the other side of the board.
