Through continued development, AlphaGo has created a unique and extremely powerful approach to the game of Go.
To articulate its innovations as fully as possible, I enlisted the help of world champions Gu Li 9p and Zhou Ruiyang 9p. Together, we conducted an exhaustive analysis of the five games between AlphaGo and Lee Sedol, and of three games AlphaGo played against itself shortly before the match. We found its ideas both exciting and inspiring, and it became clear to us that AlphaGo represents not only a scientific and technological advancement, but also a milestone in human understanding of Go. Unconstrained by human biases, and free to experiment with radical new approaches, AlphaGo has demonstrated great open-mindedness and invigorated the game with creative new strategies. Of course, no one strategy can guarantee a player’s success, but learning from these games is sure to have a positive, enlightening impact on one’s Go strength and style.
You may note that some games are shown with Black's first stone in the lower left. Although this is not the traditional orientation, this commentary presents many of AlphaGo's own analyses, so we thought it would be interesting also to give a sense of AlphaGo's perspective. The following games are presented exactly as they were entered into AlphaGo, so the reader will experience the self-play games the same way they were created, and the five-game match just as Aja Huang did when sitting across from Lee Sedol.
The variations presented herein are very complex, so I suggest you play them out yourself while reading to better understand these fascinating games.
