Apparently right now in Korea qualification tournament for becoming professional is going on. And a cheater was caught. He had a camera hidden in a button and an earpiece.
Also, the referee they mention is Cho Yeonwoo, that’s probably our youtube Yeonwoo? Maybe we’ll hear about this in her videos.
I learned about this from Dinershteyn’s group but it’s possible to google a few Korean articles. Google translate help us.
