Korchnoi v Guevara
When Korchnoi plays chess, he forgets about everything. Tal once told me that before a simultaneous display in Havana, Viktor was told: ‘You will be playing Che Guevara. He is a rather weak player, but he loves chess passionately. He would be delighted if he were able to gain a draw.’ Korchnoi understandingly nodded his head. A few hours later he returned to the hotel. ‘Well?’ Tal inquired. ‘I crushed them all, all without exception!’ ‘And Che Guevara?’ ‘Che Guevara? I also crushed Che Guevara — he hasn’t a clue about the Catalan Opening!’
