Twitch chat faced off against chess grandmaster Simon Williams last week and actually managed to pull off a win. Participants typed moves into Twitch chat, and whichever move was the most commonly input after a certain period of time would be the move Twitch’s side of the board used.

Simon Williams did win the first two games, despite being blindfolded in the second game and having the moves read aloud to him. However, Twitch chat prevailed in the final match in a very close and convoluted game. You can watch all three games here, or you can skip to the last game by going to 2:45:00 in the stream.

The match was played with Pure Chess Grandmaster Edition, which is available now for PC and Xbox One.
