The first stages of the current world championship tournaments which will produce another challenger (or the same again?) to meet Petrosian in 1969 are now under way. The West European zonal tournament, played in the Hague, was won-not for the first (or the lait) time by the Yugoslav Svetozar Gligoric with Buick (Hungary) and the twenty-three-year-old Kavalek (Czechoslovakia) the other qualifiers. Our own representative, the twenty-two-year-old Peter Lee, did creditably to score 84/16 (W5, L4, D7) without ever challenging the leaders. The following game had an entertaining finish.
