SOMTHING NEW SOMETHING NEW
He didn't, but I can see why a lot of people think he did, everything leading up to this, including his post-match analysis were very suspicious. But it's innocent until proven guilty, I think Hikaru handled it really wrong too, it's weird how he's trying to take this weird middle ground on the situation where he doesn't take a definitive stance on it, either he puts down his foot and says outright he thinks he was cheating, or he apologizes for the witch hunt that he inadvertently caused for Hans.
Magnus should also say something since he's the root of all of this, he should clarify what his tweet meant if his intention wasn't to insinuate that Hans was cheating, or just say it outright.
