Re: Hnefatafl puzzle

Evans wrote: Greetings all. What a way to enter into this forum, with an incredibly difficult and complex puzzle. There are many continuations coming off of every move, and it should also be noted that I use the term Hn before notation to show whether the Hnefi (or King if you want) has been moved....

Re: Copenhagen Hnefatafl

Is the copenhagen tournament being played allowing perpetual check? The idea being we test just the edge fort and surrounding rules? Also, how are we tackling the stalemate fort (edge fort with immobilised or garbo'ed king)? What about adding the Rule+3) If a series of moves is repeated three times...

Re: Copenhagen Hnefatafl

About the perpetual check. So, my suggested rules to avoid most draws would be: ... 3a. If a series of moves is repeated three times, the offensive player (i.e. the one performing a threat) must find an alternative move. (from Cartier) 3b. If no offensive player can be determined (due to mutual sym...

Re: Copenhagen Hnefatafl

We also thought the best way of testing this would be to hold a copenhagen rules test tournament, being that the rule adjustments came about as a direct result of experienced players competing in tournament situations. No reprogramming necessary as long as the players are all agreed when they sign ...

Re: 13x13 Tafl

I suspect though that the game dynamic will be very similar to 11x11, just a bit more drawn out. Alternative starting position for 13 x 13 tafl. It looks like something happens when switching to very large boards. Take fx. the 19x19 Alea Evangelii: http://upload.wikimedia.org/wikipedia/commons/e/e6...

That seems logical to me. I don't know why it's usually assumed that it would still use the same number of pieces.
It seems important that no white piece can reach the edge in a single move.

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...
