Alpha Go seems to play really bad moves when it is loosing - this makes some sense as humans also make overplays out of desperation, but it suggests that Alpha Go would be bad at handicap games, unless they change the algorithum to maximise score instead of win probability.

Nothing "bad" about desperate overplays while losing from Alpha Go's perspective. In the same way that it doesn't care about winning by more than a half point, it doesn't mind making its loss more crushing. Invade every territory. If it doesn't work, you lose by a bit more. Boo hoo. If it works, you might winl

I'm very interested in the fact that they coded a "resign" function into it. I wouldn't have expected that.
