Chess
Tigran Petrosyan, the newly crowned world champion, has agreed to appear at the international tournament at Los Angeles next month. He will be supported by Paul Keres, another Russian Grand Master. Bobby Fischer, the great American player, is on record as saying that it is not worth trying to wrest the world title from the Russians because of their method of secretly nominating the winner of the challenging candidates' tournament and allowing him to win matches, whenever confronted by fellow Russians.
Petrosyan in an interview in Moscow ascribed his victory largely to physical stamina which he built up ski-ing in the winter months.
