How to deal with unsportsmanlike player at chess club?
Theres a very unsportsmanlike player at our club who constantly taunts and belittles everyone else. Whenver you make a mistake he yells out "blunder!" or "inaccuracy!" ... "better move was..." and then says the engine move or what he thinks the engine move is. He also says what he thinks the engine +- is. He plays the kings gambit as much as he can and knows like 30 moves deep into every variation. If you respond something other than e5 to 1.e4 he just laughs and calls you a patzer.
He's also OBSESSED with Hikaru Nakamura. He talks about him all the time and shows everyone a picture of him with Hikaru (Its really blurry so its hard to tell if its even him). He's constantly talking about him as if he's a close friend even though he only (maybe?) met him one time. Its bordering on creepy and makes everyone uncomfortable. He calls him "Hikaru-San" which I think is part of his obsession with Japanese culture. He also brings japanese noodles/Ramen to the club every day and will spend like 5-10 minute eating them during his turn just to taunt you. Meanwhile he will be mumbling words in japanese.
We tried approaching about his conduct but he just did some weird anime villain laugh, yelled something in Japanese, then ran off to challenge another person to a blitz match. We obviously don't want to tell him not to come but it feels like his presence is deterring new people from joining and its also exhuasting.
