National Champions 2023. 2013-2017 was in UK organised every year a UK Hnefatafl Championship tournament. 2017 and 2020 were national championship tournaments run on this website. On occasion of the 25 years anniversary I'd propose that we have again national champions 2023. Counting the games only...

Improvement of Race Games Round 1 setup. At the moment players would be set up for Round 1 this way: 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 00 x x x x 01 x x x x 02 x x x x 03 x x x x 04 x x x x 05 x x x x 06 x x x x 07 x x x x 08 x x x x 09 x x x x 10 x x x x 11 x x x x 12 x x x x 13 x x x x...

Improvement of Round 2 setup. At the moment players would be set up for Round 2 this way: 01 02 03 04 05 06 07 01 - x x 02 - x x 03 - x x 04 x - x 05 x x - 06 x x - 07 x x - Player 05 has a much harder round than all other players. The following setup would be better: 00 01 02 03 04 05 06 07 08 09 ...

00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 ... 08 x x x 09 x x x x 10 x x x x 11 x x x x 12 x x x x 13 x x x x 14 x x x x 15 x x x x There's a flaw in the low end also. Round 1 is much harder for player 15 than for player 14. The low setup should be 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14...

00 01 02 03 04 05 etc. 00 x 01 x 02 x x 03 x x 04 x 05 x etc. The Round 1 setup described above (Aug. 29) still has a flaw in the top. The round is much easier for players 00 and 01 than for players 02, 03 & seq., even with a compensating extra opponent in the next round. The top setup should be 00...

Simulator runs show, that to compensate for the one less opponent in Round 1, players 00 and 01 should have an opponent more in the next round. So the Round 2 setup would for ten players be: 00 01 02 03 04 05 06 07 08 09 00 x x x 01 x x x 02 x x 03 x x 04 x x 05 x x 06 x x 07 x x 08 x x 09 x x

Improvement of Round 1 setup. At the moment 20 players would be set up for Round 1 this way: 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 00 x x 01 x x 02 x x 03 x x 04 x x 05 x x 06 x x 07 x x x 08 x x x 09 x x x 10 x x x 11 x x x 12 x x x 13 x x x x 14 x x x x 15 x x x x 16 x x x x...

World Tourn. 2023, background for the choice of variants. Copenhagen. We're used to the "Copenhagen Hnefatafl 11x11" . Hist.Hnef. 9x9: The "Historical Hnefatafl 9x9 (Saami Tablut-w)" is well tested. 11x11: Possibilities are "Historical Hnefatafl 11x11 (Welsh Tawlbwrdd)", balance -1.21 (Tawlbwrdd Be...

Good points. The game balances of Tawlbwrdd variants are at the moment measured to Variant no. of games balance Welsh Tawlbwrdd 11x11 1753 -1.21 Welsh Tawlbwrdd-w 11x11 184 +1.13 Tawlbwrdd Lewis cross 11x11 319 -1.06 Tawlbwrdd Lewis cross-w 11x11 16 -1.67 *) Simple Tafl 11x11 1375 -1.18 Simple Tafl-...

It was suitable to let the IM threshold for world champions be 1900 instead of the usual 2000. This way all world champions are IM or more.

Suggestion:
Likewise the GM threshold for world champions should be 2100 instead of the usual 2200.
