Re: Copenhagen Hnefatafl

Though the devil is often in the details. Indeed so. Thus, so far the "Copenhagen rules" appear to be: The full set of Fetlar rules [yet some discussion about perpetual check], with two additions: rule +1) Encirclement. Black wins if all white pieces are encircled by blacks, all linked together wit...

Re: 13x13 Tafl

On the 9x9 board is used 24 pieces plus the king. A simple upscaling to 11x11 board requires 24 / (9*9) * (11*11) = 36 pieces plus the king. It's interesting that this is exactly what is used on the 11x11 board. The same simple upscaling to 13x13 board would require 36 / (11*11) * (13*13) = 50 piece...

Re: 13x13 Tafl

Beadle wrote: Has anyone here experimented with 13x13 tafl? I've been thinking about the reasons I prefer 11x11 to 9x9, which, in turn, I prefer to 7x7. Maybe I'd like 13x13 even more. I won't know until I try, so I'll be building a 13x13 set soon. I suppose that aside from a different starting str...

Re: About the draw concept

Further thought on the logic behind allowing and disallowing certain forts leads me to suggest the following refinement: White win draw fort: Any draw fort that has contact with the board edge and a mobile king contained in its structure, the king having contact with the board edge. i.e. white has ...

Re: Copenhagen Hnefatafl

I hear what you are saying about the edge fort being an end game fort. You are quite right, its a last ditch effort for white, it can require fewest men, and as you say white needs black to have developed away from the edges to makes a shot at it. Even so, with it being potentially a winning positi...

Re: Copenhagen Hnefatafl

I learned it all from Richard P. Feynschmecker and his excellent books Six Easy Pieces and Surely You're Joking, Mr. Feynschmecker Thanks, I must read those; the encyclopedia says the author has a great sense of humor. At one time I attended a course of lectures on quantum physics, and it was the m...

Re: About the draw concept

The edge fort is so rare, found in only 1 out of 383 games in the games archive, that it doesn't make much difference whether this is counted as a white win or a draw. So in that sense a win-rule is superfluous. It could however in the rare cases distinguish the real master, who thus has the option ...

Re: Copenhagen Hnefatafl

I am up for testing the copenhagen interpretation, where the king can appear to both win and draw simultaneously. It sounds like a lot of fun. Before we know it we'll have sappers quantum tunneling through the draw fort walls. We have Hnefatafl players very well informed in quantum physics here! My...

Re: Copenhagen Hnefatafl

Not to forget that there is the very simple alternative solution to the "early draw problem" that white always looses if he doesn't win, so that any game where white doesn't reach a corner is a white loss (one of the suggestions by conanlibrarian above). Not that it would change the balance radicall...
