This could be another way to avoid the Monstrous Draw Fort, simple and effective. I think it might even be enough to require one black piece killed.arne64 wrote:Hello, what do you think of this idea: White can get only a draw if at least 3 black pieces are killed.

I think the problem with one black piece killed is that this can happen very early. So back can't do any sacrifices at the beginning playing a weaker player. Also this rule would legitimate draw forts at the beginning if possible. Now they are possible but not really legitimate or accepted.
That's a good idea - it means no draws in the opening game, but still allows the possibility of any kind of draw fort in the mid- or end-game. Very simple and elegant! I think this rule would rescue the Fetlar version from the draw problem. A very good refinement!arne64 wrote:Hello, what do you think of this idea:

Thank you! I think this would be great for all versions of Hnefatafl. I just had the problem in a tournament game of Scand. museums Hnefatafl where the white player drew before a single piece got killed. Also because in cand. museums Hnefatafl black is stronger it would be effective just to draw all games with white and win the ones as black to get maximum points. I think this should be avoided too!

The problem with a draw is the early center fort. And in the extreme, the Monstrous Draw Fort.Adam wrote:I can see one problem. How would this fit in with the board repetition rule? Forbidding board repetition removes draw forts unless they are specified in the rules (as in Copenhagen). In order to avoid perpetual check threats one would need to create a rule that allows draw forts, but forbids other forms of perpetual move draw positions. Tricky perhaps?
Currently these variants forbid repetitions:
Sea Battle Tafl
Moreover the attackers in Berserk Hnefatafl can break draw forts using the commanders.
The 9x9 board is too small for building a center fort.
Left are these variants, which are exposed to misuse of the center fort draw. The variants are identical with respect to doubtful center forts (like the Monstrous Draw Fort), which are built the same way in all of them:
Fetlar Hnefatafl 11x11
Scand. museums Hnefatafl edge 11x11
Scand. museums Hnefatafl 11x11
Unst unarmed king tafl 11x11
Unst unarmed king tafl edge 11x11
The past two years 1800 tafl games were played on this site. Counting the draws in the exposed variants gives 42 draws:
24 center forts
5 edge forts
1 corner fort
9 perpetual checks
2 cases of too few pieces left on both sides
1 case of white not able to move
With 0 black pieces killed:
3 normal draws and 9 doubtful draws.
With 1 black pieces killed:
3 normal draws and 4 doubtful draws.
With 2 black pieces killed:
5 normal draws and 1 doubtful draw.
With 3 black pieces killed:
9 normal draws and 0 doubtful draws.
More than 3 black pieces killed:
8 normal draws and 0 doubtful draws.
It looks like a suitable threshold to abandon draws with 0 or 1 black pieces killed and to allow draws with 2 or more black pieces killed?
That's because all black pieces are still on the board. In a discussion some time ago it was decided that white is allowed to obtain a draw only when at least two black pieces are killed; generally for all variants. So while the position is indeed a fine Two Towers draw position, alas white lost because two black pieces were not killed.skallatorc wrote:I am in the situation where a draw is inevitable but the option for draw has not shown up. Anyone know how or when that will be avail?
Update, NB: Two blacks killed before a draw is not general anymore, but now only required for Fetlar.
