Internationally mixed Open Chess Festival of San Bernardino at 1'608 metres (!) in the Swiss Alps, the number of players was restricted to secure comfortable conditions – and enough cheese :)))
winner: IM Béla Tóth (1980). Last winner: Julian Hodgson (1992). Record winner: Vlastimil Hort (1981, 1982, 1984). Highest win: Viktor Korchnoi at 8.5/9 points (1983, only participation).
surprising winner: Alexander Chudinovskikh in 1990, titleless in a 80-players field including 15 GMs, among others Gavrikov, Hort, Petursson, Hellers, Klinger, Vogt, Nemet or Flear.
Chudinovskikh (Elo 2315, he later got the IM title), living in Kirov, his journey by train and then by swiss postbus lasted six days (!), an electronic engineer by profession, was invited on behalf of Viktor Korchnoi.
He had been a pupil of him between 1963 and 1965.
Further winners were Alexander Chernin, John Van der Wiel, Paul Van der Sterren, Mišo Cebalo, and Kiril Gerorgiev. Additional Brocco co-winners (with lesser
tie-break) were Kevin Spraggett, Maxim Dlugy, Ivan Sokolov, Ognjen Cvitan, Margeir Petursson, and Swiss IM Heinz Wirthensohn.
Special event during the 10th Brocco edition in 1989: a closed Blitz tournament with
guest star Anatoly Karpov. Final standings: 1. Kiril Georgiev, 2. Anatoly Karpov, 3. Ivan Sokolov (10 players). Karpov did not take part in the regular Open.
All three Polgar sisters
played 1987 in the same (main and only) section at Brocco Open Festival in San Bernardino!
