I saw this in London as few years ago. During the chess rounds the competitors wore headphones and a commentator came into the ring and explained what were good moves, which were mistakes. Really helped novice like me.
Someone had also had a banner which read "Take his queen, punch his spleen"
This reminds me of Tesco trying to crack the US. No language barrier, and spent ages studying US shopping habits but gave up in the end. Supermarkets are hard.
