Single Elimination test, Jan. 4th - March 4th.

Tournament rules.

Start: January 4th.
Rules: The Saami Tablut rules, described here.

The tournament is a Single-Elimination and runs this way:
  1. All players are ordered by their separate rating for the variant used.
  2. First round ("Battle of Brothers").
    All players have a match against their nearest neighbours in rating to both sides, that is two matches.
    A match is a game with player A white player B black, and a game more with reverse color.
  3. If a player lost 1 match or more, he's eliminated.
    Points:
    A match has 1 point in play. A match is two games, each with 0.5 point in play.
    If a player loses a game, he lost 0.5 point (0.5 match).
    If a game is a draw, each player lost 0.25 point from that game (0.25 match).
  4. Second round ("Battle of Family").
    It is now all the way aimed at each player in each round having two opponents, one stronger and one weaker as close in strength as possible.
    And that a match is not repeated, as far as possible.
    After each round, players with a total of 1 lost match or more are eliminated.
  5. Eventually perhaps one player is left, the winner.
    Or perhaps two players, who must then have another round ("Duel").
  6. If top players are very even, they could all kill each other off. If that happens, their results against each other is counted for this round.
    In case of a tie:
    1. direct comparison of the games of the tied players (for this round).
    2. Sonneborn-Berger score calculated for this round.
    3. The player who wins with the shortest game length, is the winner. (If a game was resigned, the number of moves it would take to finish the game, is added.)
    In case of still a tie:
    New rounds between the tied winners until one player wins.
Timing x2 all the way.

2. 02.02.2022

From the first criteria above Draganov was eliminated in Round 2. There was a great risk that Dimetr could be eliminated also. Left only Asther-kane.

The elimination criteria seem to have to be changed, otherwise practically all players are eliminated in Round 2.

This would work better:
In Round 1 players with 1 loss are eliminated, this is unchanged.
However, in Round 2 players start with a clean table, and again players with 1 loss are eliminated.
That is, a round starts with losses cleared.

3. 11.2.2022

A 3rd draft of elimination criteria.

Each round starts with cleared losses.
If a player loses a full match against another player (2 games), he's eliminated. Because the other player is stronger.
(But if a player loses 1 game against one player and 1 game against another player, he's not eliminated. Because he played even against the two opponents.)

In the present test tournament Round 3 is the same, no matter whether criteria 2 or criteria 3 are used.

4.3.2022

Result of Round 3, a Round Robin between 3 players:
Draganov 0.5 loss
Dimetr 1 loss
Asther-Kane 1.5 losses

Winner of the Single-Elimination test tournament: Draganov

Conclusion: The Single-Elimination format is quick, but it would apparently give problems to use it for the WTF tourn.
