Modified:
- Or more like the Football World Cup running right now:
Round 1 is roughly half of the players, with the lower ratings.
Two winners from each group go to Round 2.

Round 2 is rest of the players plus winners from Round 1.
One winner from each group goes to the Final.

This scheme in work last year 2017 would look like this:

Registered players:
Steiger, jrton80, AreVidar, OdinHimself, edmond-dantes, animals, xerxes, altti, epm180, Kratzer, Tuireann, casshern, sqAree, Waegn, MrTopom, Hagbard, Patterson, Thanir, Fraech, DoktorKarlsrud, JKRS, emabear35, bigwurm91, tomsavini, Lbalassone, Marcin, Rasmusruge, Brench, gokstad, Ozgen97, Kihtan, Plantagenet, Agmundr, evando1189


Round 1.

1. xerxes, Fraech, DoktorKarlsrud, JKRS, evando1189
2. Brench, Kihtan, MrTopom, emabear35, Ozgen97
3. Marcin, jrton80, Waegn, tomsavini, gokstad
4. Tuireann, AreVidar, Patterson, Lbalassone, Rasmusruge

Perhaps xerxes, Brench, Marcin, Tuireann, AreVidar, jrton80, Kihtan and Fraech would've won and gone to Round 2.


Round 2.

1. casshern, Agmundr, xerxes, Brench
2. Plantagenet, Bigwurm91, Kratzer, Marcin
3. OdinHimself, altti, epm180, Tuireann
4. edmond-dantes, Hagbard, Steiger, AreVidar, Fraech
5. animals, sqaree, Thanir, jrton80, Kihtan

Perhaps casshern, Plantagenet, OdinHimself, edmond-dantes and animals would've won and gone to the Final.


Round 3, the Final.
casshern, Plantagenet, OdinHimself, edmond-dantes, animals

And as we know, Plantagenet won.

- Or also two from Round 2:
Round 1 is roughly half of the players, with the lower ratings.
Two winners from each group go to Round 2.

Round 2 is rest of the players plus winners from Round 1.
Two winners from each group go to the Final.
Right now 26 players registered for the 2018 tournament.
About 26/2=13 would start Round 1, split in 3 groups of each 4-5 players. 6 winners would proceed to Round 2.
Round 2 would have 13+6=19 players, split in 4 groups of 4-5 players. 8 winners would proceed to the Final.

Time controls:
Round 1: 0.5 day per move. Time buffer 5 days. Long-game-threshold 7 days.
Round 2: 0.75 day per move. Time buffer 7 days. Long-game-threshold 10 days.

The Final would be very demanding with many high level, hard games. So the time controls should be doubled:
Final: 1 day per move. Time buffer 10 days. Long-game-threshold 14 days.
(But rematches, if any, again 0.5 day per move, time buffer 5 days and long-game-threshold 7 days.)

Quadrathlon 2019.

I propose a quadrathlon like the one we had a year ago.

1. Copenhagen Hnefatafl 11x11, using the results from the World Championship.

2. Berserk Hnefatafl 11x11, starting January 1st 2019. The winner is Berserk Tafl Master 2019.

3. Historical Hnefatafl 11x11 (Welsh Tawlbwrdd), starting January 15th 2019. The winner is Historical Tafl Master 2019.

4. Sea battle tafl 13x13, starting February 1st 2019. The winner is Sea Tafl Master 2019.

The quadrathlon score is calculated for players who participated in at least two of the four tournaments. The winner is Quadrathlon Tafl Master 2019.

Timing: 1 day per move. Time buffer 10 days. Long-game-threshold 14 days.

This is my bid for an evaluation of the Championship Tournament 2018:

The tournament setup this year was much different from earlier years, and in my opinion the best setup which has been tried on this site.

What worked well.
- Three rounds.
- Aiming for six players per subgroup (hat tip: Casshern).
- Always two players from each subgroup to move on to the next round.
- The players were given three days notice between rounds.
- That Dmitry Pashkov kindly offered three attractive prizes for the three top winners. This increased the tournament suspense!

What could be improved next year.
Running tournaments on the internet opens for a wide range of opportunities for cheating.
Just to mention a few:
- Multiple profiles with fake IP addresses.
- Copying moves from one game to another (Ex.: C is weaker than both A and B, but B is weaker than A. C copies all A's moves to his games against B and thus beats the stronger player B).

It is a problem how to reveal cheating on the internet.


The winner was found after 89 days (last year 83 days), and the whole tournament was finished after 101 days (last year 87 days).
26 players joined the tournament, and 22 players saw it through.
In total 184 games, 7655 moves and 1175 killed pieces. 100 white wins and 84 black wins (game balance +1.19).
Longest game was 149 moves.
Shortest game was 14 moves.

Congratulations to World Tafl Federation Champion 2018, Mario Aluizo ("casshern"), Los Angeles, USA!
Many thanks to Adam Bartley and Mario Aluizo for being umpires, and to the 26 players who played in the tournament!
