Re: Compiling a list of openings

This is still somewhat preliminary. Do the diagrams show, which is the most winning start move? And the most winning answer to that? And the most winning answer to the answer etc.? You can definitely extract the best first move from what I've compiled...look at the document at http://aagenielsen.dk...

Re: Compiling a list of openings

And here's the largest cluster, about 47% of examined records fit into the cluster. So the diagram shows that d1-d3 is the most winning opening move of Copenhagen Hnefatafl 11x11? And the two most successfull answers are e5-e2 and f4-c4? And the most used and successful third move is f2-i2 (probabl...

Re: Compiling a list of openings

And here's the largest cluster, about 47% of examined records fit into the cluster. That makes sense, it's close to balanced, with white having about a 57% chance of winning when the board is close to this configuration. Still, it does offer a small advantage to white and may be worth pursuing from ...

Re: Compiling a list of openings

Here's the "family" of openings corresponding to the cluster above. Note that many begin in different portions of the board bu are "similar" based on the symmetry of the board. h11-h9/f4-c4/h1-h3/e5-b5/ h11-h9/f4-c4/h1-h3/e5-e3/ a8-c8/h6-h3/k8-i8/g5-i5/ h11-h9/f4-c4/h1-h3/e5-e2/ a8-c8/h6-h3/k8-i8/g5...

Re: Compiling a list of openings

Update: So I clustered the all the Copenhagen Hnefatafl games and identified a large number of clusters with very similar board positions at the end of the first four moves. This required that I turn each move sequence into a representation of board positions and correct for boards that are rotated ...

Re: Compiling a list of openings

I was interested in maybe using some moderately advanced statistical techniques to cluster similar openings from the game archives and assign win probabilities to each opening. I extracted the first four moves from all games between strong players for the most used variants: http://aagenielsen.dk/t...

Compiling a list of openings

Hi all! I'm new here and very curious about the theory underlying different kinds of Hnefatafl. In my real life, I'm a data scientist and I was interested in maybe using some moderately advanced statistical techniques to cluster similar openings from the game archives and assign win probabilities to...

Re: Member introductions

New here. Hello all.

Drawn into the game via Tablut, learning to really enjoy Copenhagen Hnefatafl now.

Obviously I'm still quite bad at the game but looking for resources to improve my play.
