This game was largely played extremely well by both sides. There were a a few peculiar-seeming moves made by AlphaGo that the commentator found very atypical. These moves ended up playing a very important role in the end game. I should also say that it's somewhat clear that Sedol made one suboptimal move, and AlphaGo capitalized on it. Interestingly, the English commentator made the same mistake as he was predicting…

If AlphaGo wins all 5 matches, what do you think DeepMind will do with it? My intuition is that they won't continue development, and instead focus on other applications. Great game btw, a pleasure to watch.

There's still Computer vs Computer, we also might see Freestyle Go (just as in Freestyle Chess).

I would assume the development will continue.

At the same time, only now are people seeing how its hard for people to play Go against computers. Until AlphaGo I didn't even think computers were close.

I know how hard it is. I still cannot beat my 15 year-old PDA when playing chess with it. The intelligence of Lee is far higher than I can interpret.

Go is much harder than chess. The tree of available moves is massive and difficult to prune, as it's hard to get a reasonable heuristic about the "strength" of a given Go position.

Why wouldn't you allow that? Surely the human thinks in the computer's time.

So that the human has a chance... Increasing the human time is not an option, since no one wants to watch 8 hour games, and fatigue could also come into play, so the only real option for a winning chance is reducing computer time/power

You do not have to watch it live. Correspondence chess is a real thing (https://en.m.wikipedia.org/wiki/Correspondence_chess), with fewer blunders than tournament chess.

Correspondence go, similarly, would see fewer errors. Holding a world championship would take quite a bit longer than in chess, though (rough guess: 300-ish half-moves per game versus 100-ish half moves, the latter, I guess, with a bit more variation). That could be problematic, as a world championship in chess already takes years (curiously, some championships finished before the one started a year earlier did)

Is there a complete recording of the commentary? They had one for game 1. The current live stream only goes back two hours and doesn't include the beginning of the game. I'm looking at the DeepMind channel on Youtube: https://www.youtube.com/channel/UCP7jMXSY2xbc3KCAE0MHQ-A

I tried to watch commentary on the DeepMind channel for game #1 and found it to be very un-informative: I recommend the AGA channel (although it's been linked a few times): https://www.youtube.com/watch?v=6ZugVil2v4w, still waiting on the game 2 static video.

They put a version of the broadcast up after it is finished, if last time is anything to go by. Took a little while because the stream is still going, with the press conference.

StarCraft is their next challenge. :)

Yes, the AGA version was better. Unfortunately they aren't broadcasting for the next game on Friday. At least that's what they said.
