AlphaGo vs Lee Sedol

"A slack move is a move that looks lazy. You can see these other better moves & AlphaGo is rejecting them but what I think AlphaGo is teaching us is that we've been using score as the proxy for chance of winning. The bigger my margin of territory the more confident i am that i'm going to win. And AlphaGo is saying NoNoNo it shouldn't matter how much you win by you only need to win by a single point. Why should I sieze all this extra territory when I don't need it. The lessons that AlphaGo is teaching us are going to influence us how Go is played for the next 1000 years." - Frank Lantz (Director NYU Game Center)
