This is impressive. According to the article, the bot has not yet lost. I think at the end of 2017, we may have to say that computers have conquered Go. Interesting that the timing is 20 years after mastering chess.

It's important to note that the games were played on a fast-paced "blitz" time setting where AIs are particularly strong compared to humans.

I can already barely follow what is going on on the board, so I'm sure watching slower paced games against pros would be interesting.

One thing that isn't made clear in this writeup is that Master plays in a very nonhuman style, as opposed to the version of AlphaGo that beat Lee Sedol, which mostly played like a strong human except for a few surprising moves. My first guess when I saw Master's games was that it was a program like AlphaGo that had its policy network trained from scratch rather than being bootstrapped by being given the goal of imitating the moves of strong humans. I'm eager to find out whether that was the case or whether it just moved away from human-like play during a very long self-play phase.

It really is a bit scary to see. I would not have guessed that human strategy was that deficient. Computer chess programs still tend to play with human-like strategy (partially because humans have coded their evaluation functions!) but godlike tactics. Master is not really playing like a human at all.

Can you give some examples of what you consider non-human? Really curious since I don't know much about common strategies in Go.
