I like watching Hikaru's youtube videos.
His commentary on the games is very descriptive, unlike other players that stay quiet for most of the game. Hikaru's always talking, letting you know what's going on.
However, one strange thing I've noticed is the COMPLETE absence of any sort of online interaction with Magnus. He's uploaded hundreds of videos, yet none contain matches against Carlsen.
I thought this was strange, since I know Carlsen plays a lot online too, and Hikaru's got matches with a lot of other top players, but never Carlsen.
The other day, I noticed a youtube comment in his video that said "play Carlsen", and somebody responded with "we don't mention that name here", and it got tons of upvotes.
So I am clearly out of the loop here: what's going on? Why is Hikaru actively (seemingly) avoiding Carlen online?
