2. The list marks the attribution of Ke Jie as uncertain when playing as Wen Bie.
3. Game 55 is listed as a 2 versus 1 team game. Do we know under what conditions Chen and Meng played?
2. Wen Bie (Kissing Goodbye) was not officially confirmed as Ke Jie, but everybody has assumed it's him due to various reasons, and he did tweet out some thoughts regarding the new AI on Weibo after losing his first two games there.
3. Chen Yaoye was the one playing, with Meng sitting behind him making possible suggestions. They were at the Weiqi TV studio with the game broadcasted live. From watching the replay, I don't think Meng helped much at all.
