Inspired by the Edmond-dantes discussion about a new tournament format (knock out) with fewer games, I'd propose a change to the next World Championship tournament:

Grand Masters who were in the Valhöll one of the latest two years, have Round 1 in a Valhöll Door group if they register.
Likewise International Masters and Quadrathlon Master if they were in the Valhöll final last year.

This goes for
Plantagenet (GM and Valhöll final 2017)
Herjan (GM and Valhöll final 2016)
Adam (GM and Valhöll final 2016)
Crust (GM and Valhöll final 2016)
OdinHimself (IM and Valhöll final 2017)
Casshern (QM and Valhöll final 2017)

If there are not registered 5 players for the Door group, it is supplemented with more players from the Valhöll final last year until 5 players is reached.
That is
edmond-dantes
animals
sqaree

After the Valhöll Door round, the top two group winners go to the Valhöll final. If there are only two players registered in the group, then there's no need for a Round 1 for them and they go straight to Valhöll.

All other participants have a Round 1 in groups as usual, and the group winner goes to Valhöll final. 27 players fx. in 3 groups of 9.

Let's see how such a rule would have worked last year:

At the World Championship 2017 these players were qualified for the Dyrr Valhöls group (Old Norse for Valhal's Door):
Herjan
Crust
Adam
Altti
- and possibly
Sigurd
bigwurm91
Hagbard
xerxes
Tuireann

Only Altti, bigwurm91, Hagbard, xerxes and Tuireann registered and would all have been in the Door group.

29 more players registered. They would've been split in 5 round 1 groups of each 6 players, resulting in 5 or 6 round 1 group winners for Valhöll.
At last the Valhöll final with 6 or 7 players.

The next World Championship tourn. in September could have 3 rounds:

Round 1:
Players distributed in groups of 3 or 4.
The groups are named after Midgård viking locations, Vinland, Fornebei etc.
The group winners proceed to round 2.

Round 2:
Players again distributed in groups of 3 or 4.
The groups are named after Asgård figures, Odin, Thor, Loke.
The group winners proceed to round 3.

Round 3:
The final round.

Masters have their own route to the final as explained in a post above.


If this scheme had been used last year, then the tourn. would have taken 66 games and about 3 months.

Here's my proposition for the World Championship tournament rules this year, starting Sep. 15th.

Notice that a short route to the final is proposed for the masters.
It's proposed that only group winners proceed to the next round. But all of us who don't expect to make it all the way, should join anyway to give the stronger players a hard time, so that it will not come to them too easily!


Sign up: all July, August and half September. There will be a button for registering for the tournament.
Start: September 15th.

Tournament rules.
The Copenhagen rules, described here:
http://aagenielsen.dk/copenhagen_rules.php

Points are 1 for won, 0 for lost and 0.5 for a draw.
Umpire: xxx. For xxx's games, umpire is yyy.


Masters' qualification round.
Certain masters have only one qualification round before the final.
Their group is "Dyrr Valhöls" (Old Norse for door of Valhal).

Players starting in Dyrr Valhöls are (if they register to join):
Grand Masters who were in the Valhöll final one of the latest two years.
International Masters and Quadrathlon Master who were in the Valhöll final last year.
If this does not make 5 or more players, then the group is supplemented with more players, first from the final last year, and if necessary also from the final two years ago.

This year these players can start in Dyrr Valhöls:
Plantagenet
Herjan
crust
Adam
OdinHimself
casshern

and these players are in queue for supplementing up to 5 players:
edmond-dantes
animals
sqaree
Sigurd
bigwurm91
Hagbard
xerxes
Tuireann

The top two (!) winners proceed to the final.
If from the whole list only one or two register, they go directly to the final without a preliminary round.


Normal qualification rounds.
All other players have a round 1 in groups of 3 or 4. As usual distributed through the Thue-Morse sequence based on ratings.
The groups have viking locality names like Fornebei, Vinland etc. (Midgård names).

The group winner from each group proceeds to round 2, again in groups of 3 or 4.
The groups have Asgård figure names like Othinn, Thorr and Loki.

The group winner from each group proceeds to the final (Valhöll).


In case of a tie, as usual for all games:
1. direct comparison of the games of the tied players (for this round).
2. Sonneborn-Berger score calculated for this round.
in case of still a tie:
3. preliminary rounds: both players proceed. Final: new rounds until one wins.

Timing is as for all other games.

If at any time you want to leave the tournament, just say so, or press the Deregister button.
If a player does not move at all in a round before he times out, he is removed from the tournament.
A player who causes more than half of his Round games to time out, is disqualified from the tournament.

Right now an American Championship Tournament 2018 is running (North & South America).

What about a European Championship Tournament 2018 beginning Sep. 15th? For players not in North or South America and not already grandmasters. Winner is International Master.
If the World Championship is run as proposed above, then its Sep. 15th round 1 is not very hard, only a very mixed group of 3 or 4 players. So there could be surplus energy for this too.

The European tournament had 11 players last year, so it would better to take two rounds.
(In case of 11 players: first round 2 groups of 4 and 1 group of 3. Second round only the 3 group winners).

Example:
With the same no. of players as last year, 29 for the World Championship and 11 for the European Championship, then the no. of games for a player who attends both and goes all the way would be:
first month 4 + 4 games in round 1
second month 4 + 4 games in round 2
third month 8 games in round 3
