"I think in these mini-matches a lot will hinge on a single game," Carlsen told Take Take Take when asked about whether he was surprised that Caruana vs Gukesh match was so one-sided. "Yesterday's game could have gone either way and today of course it was never very likely that Gukesh was going to come back and honestly I think he made a kind of prudent decision just resigning when he realised that he was not going to make a comeback. Just see it as a bit of a lost event in that sense. "He had his chance yesterday, he didn't take it and then you move on."
