There are really good fundamental reasons to set it off from scratch too - once you program anything into it beyond the rules you have to fix on some sort of abstractions to definite it all with. Get those wrong and you can really limit its ultimate strength.

A bit like how using existing Go games to train AlphaGo left it with some ultimately unhelpful human derived hang ups....

Deep mind are showing fairly strongly it works better to let the computer pick these sorts of things out itself :) Nothing left for us to do but worshipping our silicon overlords ;)

The other thing about the training is that I presume that those 3 billion games won't have all been purely random by any means - the first X% will have been, later on it'll have been a mixture of 'intelligent' and random moves and near the end it'll have been playing nearly all intelligent moves.

I have just gone through the 10 published games from the match. Alpha Zero is amazing. It does not play like any computer program I have ever seen before. It seems to me more a superhuman initiative seeker, with a real sense of just going for it. Tal on steroids. The depth at which its material sacrifices are seen to be justified is staggering. Beautiful stuff. Of course, this is preliminary, as there are the other hundred odd unpublished games, which may ultimately give a different impression. I'm not sure who it was selected the games to be published, but do you get the feeling they liked seeing the Queen's Indian getting tin canned? Chuckle.
