Keres' run of four successive second places in Candidates' tournaments (1953, 1956, 1959, 1962) has prompted suspicions that he was under orders not to win these events. Taylor Kingston concludes that: there was probably no pressure from Soviet officials, since from 1954 onwards, Keres was rehabilitated and Botvinnik was no longer in favour with officials. At Curaçao 1962, there was an "unofficial" conspiracy by Petrosian, Geller and Keres, and this worked out to Keres' disadvantage, since he may have been slightly stronger than both Petrosian and Geller at this stage.
