  • There was no playoff. Lubomir Kavalek and John Grefe remained Co-Champions.

  • William Lombardy withdrew hours before the start of the tournament, too late to be replaced, and so the tournament continued with an odd number of players and a bye each round.

  • Report, Chess Life & Review, November and December 1973

  • Robert Byrne did not defend his title, as he was playing in the Leningrad Interzonal, from which he qualified for the 1974 Candidates.

  • This was the first US Championship tournament held outside New York State, and only the second one (1948 being the first) held outside New York City.

  • Coverage in the November, 1973 issue of Chess Life.
