@multix "Yes, please report. Chess is... at least should be a gentlemen sport. I can't imagine Carlsen trash-talking ... over the table ... not even a little bit."
So guess what? You don't have to "imagine" Carlsen trash talking, you can simply WATCH and LISTEN to him trash talking on at least half a dozen yt vids. Reality is apparently much richer than your imagination. For instance, search:
Magnus Carlsen trash talking vs. World Top 100 Grandmaster - Speed Chess
And several others. Maybe you had better report him to Google.
