Russian grandmaster Daniil Dubov, who defeated R Praggnanandhaa (Pragg) in FIDE World Cup in fourth round tiebreaks on Thursday, said he dislikes classical chess and prepared for just 10 minutes. Dubov stated that Praggnanandhaa (Pragg) spends "day and night looking at chess but he had failed to pose a single problem" to him in their classical games.
