Fan Hui is speaking to a chatty audience at the 2016 European Go Congress in St. Petersburg, Russia, gushing over a game of Go played by one of his mentors. Hui's enthusiasm is infectious--the room's chatter subsides as he pulls up slides of the complex Chinese game, whose players battle to dominate a 19 19 board with black and white tiles called stones.
