Are you a math student?
If math wouldn't be my profession, I probably wouldn't dare to speak so freely. Though I have to admit, that I did some programming since then.

Are you talking about edge forts? That might totally be. I was using that technique for edge forts during my games.
Yes, you could use retrograde analysis to develop an edge-fort engine.
While you might be right about that, it sounds complicated and seems less useful than a basic answer on plain corner attacks.

The real truth about this is that I don't know how to go about it. Furthermore it's hard to test, because the edge fights are just a result of massive weaknesses black created during defending corners. So until we understand how these corner attacks work, it's hard to determine which kind of edge forts are interesting.

At the same time you are right about the fact that a naive "just do some machine learning without prior knowledge", is way to naive to get a result for edge forts in a reasonable amount of time. It's just to hard to construct one "by accident". I was planning to leave that issue for later, but if you have any ideas I'm all ears.

Didn't the original AlphaGo program also do local tactical analysis separately from global strategic analysis?
We always have graph based based pruning techniques.

Afair there were never a special part for tactical or strategical results. At the same time we have two different outputs (that were attached to entirely different networks in the first version), while one looks for "interesting moves" (in particular all tactical ones) and the other one is trying to give an estimation who has the upper hand (essentially giving a strategic judgement).

I studied mathematical logic, what's your field?

It looks like neither of us are serious enough about programming tafl: if you were serious you;d start with brandubh, if I were serious I'd be using C. :)

I guess I was wrong about that, I must have misunderstood something I read about NN valuation v. MC search.

My field is topology.

I'm serious about Copenhagen, yet I'm ready to start with a variant without edge forts to keep things simple. I'm not aiming for a (even much harder) general solution.
