. .. Kt (7) else ; 2 Q—B 5. P—B 4 ; 2 Q—Kt 7. Good early example of a straight-forward 'waiter', where key move leaves position substantially un- changed.

One of the most dangerous attacking players in the world is the East German champion, Wolfgang Uhlmann : it is a little surprising to me that he has not yet managed to reach the Candidates tournament.

Last year, in tying with Smyslov for first place in the Capablanca memorial tournament at Havana, he

brought off one of his finest performances. Here is a win against one of the tail-enders—not a great game, but a piquant finish. (Smyslov, incidentally, won this year's Havana tournament, followed by Ivkov, Fischer and Geller.)

a P—Q Kt 3 . . . The East Germans have made a speciality of the French Defence; aware of this, Santa Cruz plays to get the game into unknown territory where natural abilitY rather than knowledge will .count. Unfortunately, Uhlmann's

advantage in ability is at least as great as his advantage in knowledge.
