Gu Li and Ke Jie played each other (in a jubango -- a ten game series -- in 2014: an excellent series of games!). AlphaGo did not play Gu Li unfortunately.
Ah, I read that wrong, I thought he meant Alphago not Ke Jie.
Exciting times, I can't wait. I guess the later the game will be, the less chance Ke Jie has.
The jubango was between Gu Li and Lee Sedol. Not Gu Li and Ke Jie.
