PW[Master]PB[Gu Li 9p]DT[2017-01-04]
C[White:  Master
Black:  Gu Li 9p

After defeating Huang Yunsong 6p, Master faced further challenges from Nie Weiping 9p of China, Chen Yaoye 9p of China (this time he was able to play to the end, and, in fact, it was revealed that he was aided during the game by Meng Tailing 6p), Cho Hanseung 9p of Korea, Shin Jinseo 6p of Korea (who just that morning lost to Mi Yuting 9p in the Limin Cup World Top Star Final), Chang Hao 9p of China, and Zhou Ruiyang 9p of China.  In all six games Master emerged victorious. 

Aja Huang has chosen this moment to confirm his identity.  That is, Master is indeed a new edition of AlphaGo.  These lines appeared in the online chat with Master:

"Master:  I will play my final game with Gu Li sensei.
"Master:  I hope everybody has enjoyed Master's games these few days.
"Master:  I am Dr. Huang with AlphaGo."

So Gu Li is the final opponent to Master/AlphaGo.  And this also seems to imply that this is the last game of the Master phenomenon.]

;W[df]C[Here is a post by Ke Jie:

"My thanks go to the striking new edition of AlphaGo.  Since I knew Master's true identity from the very beginning, I have been hoping for at least one win by the human race.  I even spent the last week to prepare a 'last resort jujitsu'.  Alas, I find myself in the hospital instead.  Well, I am slightly disappointed, but I hope Gu Li will show the ultimate strength for our human race!"]
