The tournament in question was the 20th USSR Championship, held in
Moscow in 1952. Can anybody fill in the details of the dispute between
Botvinnik and Taimanov?

'Botvinnik complained in his memoirs that his former pupil Taimanov
agreed to an early draw in principle, but played on when they got
closer to the 30-move mark with Botvinnik having relaxed his
concentration.' - Cafferty & Taimanov, 'The Soviet Championships' (p.
