Re: Skalk Hnefatafl 11x11

Skalk Hnefatafl 11x11, rule of surrounding. The Skalk rules state: The attackers win by taking the king. This is achieved in the usual way by sandwiching between opposing pieces or against a corner-square, but if His Majesty is standing upon his centre-square it is necessary to sandwich him in on a...

Received a first analysis, to be read here: http://aagenielsen.dk/openings_version_1.pdf Brench writes: This is still somewhat preliminary. I can probably do a better job clustering the data and I will expand the writeup as time goes on to better explain how to use the document. For now I think I'll...

Re: Rating

maybe we should just make different ratings for each variants and display them in a different menu. ... I would also suggest to give only a k-factor of 16 (the half) if the player played a basic amount of games. Between Grandmasters in chess a k-factor about 10 is used. We have to fast changes if j...

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

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...

Re: General rules

On preventing that a game is stuck in repetitions. Repetitions were discussed at length in 2012. Here just a few comments. If repetitions were to be counted as repetitions of full board positions, and the player to lose were to be he who first entered this particular board position, then this way o...
