Re: Copenhagen Hnefatafl

Following the fun science references, Crust and I have been referring to the rules now being tested on Aage's site as the 'weak' copenhagen interpretation, and a version forbidding perpetual check as the 'strong' copenhagen interpretation. Otherwise the rules are the same. Strong and weak copenhage...

It was easy for white to lure the computer into this perpetual check. It's hard to tell, but if it's also possible against a human opponent to from the start quickly go for perpetual moves, and easier than to win, it can be abused.

Here white attacks on a full line, and black must use not one but several pieces to block.

Re: About the draw concept

Evans wrote: Thanks Hagbard for bringing that up, because that is something that has been worrying me about the Copenhagen rules for a while. White can still go into the match looking for a 'drawing draw fort', so he could still easily build a centre fort as long as he puts two pieces at the edge o...

Re: Copenhagen Hnefatafl

More on forts. http://aagenielsen.dk/centerfort2_r.png This draw fort is easy to do against the computer; just move two white pieces to the edge, keep the rest in center and arrange them as a fort. White can go for the draw from start, so this could be another source of abuse . http://aagenielsen.d...

Re: Copenhagen Hnefatafl

Evans wrote: Sorry conanlibrarian! Yes, I think in edge Tafl it is certainly needed for a rule forbidding perpetual check. The most convincing argument (and again the simplest) is probably that if a perpetual checking move is repeated, then the offensive side must find an alternate move, and that p...

Re: Copenhagen Hnefatafl

Evans wrote: On the perpetual moves rule, I personally find that it would be a lot easier to call all of them a draw. I draw this simple conclusion off two things. The first is that the situation is so rare. Generally, it is unsatisfactory because both players have not had the power to control a ce...

Re: About the draw concept

More on perpetual checks. And with the addition that any repeat move that involves a checking move may not be repeated more than 3 times, at which point the checking player must make a different move. In all these cases, one of the parties ("the attacking party") is trying to accomplish something w...

Re: Notation

Evans wrote: Your last note, crust, is rather interesting. That Black plays first may be a little confusing for players who have come to the game right off chess, but that brings up an intriguing point. For all that we complain about our lack of knowledge of Tafl from the Old Norse Sagas, we have i...

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....
