The First Piatigorsky Cup brought eight grandmasters from five countries to Los Angeles for a double round-robin organized by Jacqueline Piatigorsky, a strong player and generous patron and the wife of the cellist Gregor Piatigorsky. The Soviet players Paul Keres and the new World Champion Tigran Petrosian finished level on 8½/14 to share the cup.
A patron's tournament
Jacqueline Piatigorsky endowed and organised the event, gathering eight of the world's strongest players for a double round-robin of fourteen rounds — 56 games in all — at the Ambassador Hotel. The prize fund was $10,000, with $3,000 for first, then an unusually rich purse for a chess tournament in the United States.
The field spanned five countries: Keres and Petrosian of the Soviet Union, Miguel Najdorf and Oscar Panno of Argentina, Friðrik Ólafsson of Iceland, the American pair Samuel Reshevsky and Pal Benko, and Svetozar Gligorić of Yugoslavia. Bobby Fischer, then 20, was invited but declined after his request for a $2,000 appearance fee was refused.
A series is born
The Piatigorsky Cups were the strongest tournaments held in the United States since New York 1927, and this first edition set the template: a small, elite double round-robin, generous prizes, and world-class organisation. Its success led directly to the Second Piatigorsky Cup at Santa Monica in 1966 — a still stronger field that produced the celebrated Spassky–Fischer finish.
