AlphaGo

"AlphaGo's way is not to make territory here or there, but to place every stone in a position where it will be most useful. This is the true theory of Go: not 'what do I want to build?', but rather 'how can I use every stone to its full potential?"

"...there was a cut that quite shocked me, because it was a move that would never happen in a human-to-human Go match. But, afterwards I analyzed the move and I found that it was very good. It is one move with two or even more purposes. We call it one stone, two birds."
