I don't know about AlphaGo, but this is a position about which Go Seigen was ambivalent. In his 10 book set, 21st Century Go, there is one place where he likes it for White, one place where he doesn't.

We're still within an opening that has been played by pros - there are 3 games on ps.waltheri.net with this sequence. (I find it interesting that two of them involve Cho Chikun, but he played black in one and white in the other. Also, it's a bit weird to be playing a game where I can reference what moves the pros played. I've never played an open book game before.) In all cases 15 and 16 were the standard moves.

I don't have a reason to consider a different move, but I do need to consider whether it should be a king or a pawn. In all of the pro games the stones in the corner stayed connected, but I think that if I made this stone a king black could get a result better than the normal corner by forcing me to play defensively after a hane at f2, like so:

I have to play passively at 4 instead of breaking out of the corner with a move like a because I can't sacrifice 2. There are also lines that would involve sacrificing my original king stone, which I can't do.

It's interesting playing this variation. It makes me think about the threat of sacrificing even when I don't intend to do so. It's hard to consider that several moves ahead, but I can't add as many kings to this corner group as I had hoped. Things should be more clear after the next move, though.

The left and the bottom seem like obvious places not to play right now, which leaves the top or the right hand side.

The two stones in the lower right are nice to have, and White is not fully settled, but the top is also nice for W.

All told, I'm leaning towards the sanrensei, if only because I feel like I understand the position more.

A further question is how to evaluate the influence vs territory trade that we've made so far, relative to an ordinary game of go. Say in normal go, the expected score in this position is +/- X. How does the expected score in this game compare? There are 5 white kings already played, which is one component. There is whatever loss of flexibility white has from those kings, which I think is small on this board. Then there's the value of Black's moyo. Is it larger than it would be in regular go, or can White claim those 5 points as pure profit? It's hard to tell, but I think this position is probably better for White than the corresponding position in regular go. Hopefully I'm wrong about that.

I've finally decided to include territories in the score. After all, there's a reason why Go evolved from stone scoring to area scoring.

Needless to say, this shouldn't affect your ongoing game, which was started with the old rules.

hyperpape · **#56**

Q10, pawn.

Luigi: that means no group tax right? That slightly changes things, but I don't think I've made any decisions based on it.

Yes, that's right.

The rules are a bit longer this way, as there needs to be a definition of territory, but in the end I think practicality is more important. My original post in the Kingo thread now reflects this change as well as the use of integer komi and the button.

jeromie · **#58**

I'd like to stick with the original rules. I prefer them as outlined in the other thread, and I have made decisions with the group tax in mind.
