Re: Hnefatafl Internet Championship

Even in the preliminary rounds? If we are unlucky player A, E, I are in the same group, 2 players should advance, but player E and I both got for example 8 points and both won the black game against each other. I suggested this 1. points (he archived this round) 2. direct comparison (skip this for w...

Re: Copenhagen Hnefatafl

I still can't see the huge advantage of black. I agree blacks position looks strong, but it's far beyond my ability to make it to a certain win. I guess the reason is also psychological. If we loose with black we usually see how white crushed us down and what defending moves we missed. We instantly ...

Re: Hnefatafl Internet Championship

That's nearly my fist suggestion. Just the algorithm of contributing the players to the groups differs. We should keep the algorithm clean, but you might be right that it is better if we use the rating for distributing the players over the groups. I suggest that kind of creating the rank: 1. points ...

Re: Copenhagen Hnefatafl

It is. It also covers the game between altti and me last tournament (that's the reason I didn't agree the draw), but it seems hard to test, because you have to retrace the whole game if you want to test whether the rule matters. But I would suggest to change it to "white have to find another move". ...

Re: Hnefatafl Internet Championship

Perhaps just as well go the whole length and use a 20 day-limit for all games of a championship tournament. That double the needed time. If we have to many participants, that take a lot of time. If matches which were carried out already in the first round, were to be repeated in the second round, t...

Re: Use of tafl variants in real life tournaments

The Vikings had much less opportunity to compare good strategies then we have today. I like to draw back a line form the vikings, but I have to admit that want also promote Hnefatafl as a game itself and not only as a nice to know as part of the Vikings. And most assumptions that are made so far doe...

Re: Hnefatafl Internet Championship

With that suggestion you take the advantage of the 20 day-limit for the final away again. If I loose first round (10-day limit) through a time out that might disqualify me to reach the top. My idea was to get the best players to the top. "I lost through timeout against a strong player in the first r...

Re: Rating of tafl games

The main problem here is that you get a medium rating (no matter where you start) by participating in test tournaments and anyways your rating is totally flipped by just loosing a two games in a row against a player that have some difference to you (for example I lost 31 points against you in just o...

Re: Balanced 9x9 and 11x11 tafl variants

Salk Hnefatafl even on a 9x9 board seems to be in favor for black. The king is just to hostile. Sea battle tafl seems to be better balanced, but much easier to play for while. Sea battle tafl leads to very fast, very tactical game. I'm still very bad at that variant.

Re: Rating of tafl games

I would also suggest to give only a k-factor of 16 (the half) if the player played a basic amount of games (20 or 30).
Between Grandmasters in chess a k-factor about 10 is used.

We have to fast changes if just one or two games are lost.
