U.S. Championship
With Bobby Fischer and Samuel Reshevsky already signed up, along with most of our topflight talent, another great tournament for the U.S. Chess Championship is anticipated. It will be held at the Henry Hudson Hotel in New York from Dec. 15 to Jan. 3.
William G. Addison, who finished in third place last year, will again participate. Others who have accepted invitations are Pal Benko, Arthur B. Bisguier, Donald Byrne, Robert Byrne and Dr. Anthony Saidy. Larry Evans is also a likely contender.
Defending champion Fischer, who has won the tournament five times, will still be the youngest competitor, with his 21st birthday in March. He has lost but one game outright in this series, in the first round to Edmar Mednis last year.
