So Magnus is playing in the Qatar Masters and he just lost with the black pieces against a 2512 rated GM.
For context, to attain the GM title you have to get "GM norms" which is having winning performances at tournaments with an international list of GMs playing at said tournament. You also have to be over 2500 rating.
So Magnus just lost to a dude who is barely a GM.
After the game he tweeted out that the dude didn't cheat and played a great game. Then he immediately went on to complain that the guy was wearing a watch (not digital or anything, just an expensive looking analog watch) and that he lost because he couldn't concentrate once he saw this guy had a watch. Wearing a watch is supposedly against FIDE rules, but the arbiter said it was cool when Magnus brought it up.
So either Magnus comes up with an excuse every time he punts off a game against a much low rated opponent or he's legit so terrified of people cheating against him that a watch will send him into a tailspin.
