Rules
-
This is a quick-reference version of the information on the
TTT Info page.
If you have any questions, that's where to go first. ;-)
Starting matches
-
Each player will be provided with a personal page which must be
used for inviting their opponents to a match.
-
All invitations must be made as soon as possible. Play must be as fast
as you can comfortably manage such that this round is finished by the
end of the month.
-
If two or more matches are started between any pair of players, the one with
the lowest match id will be deemed the official one and the other will be
deemed a friendly match.
Scoring
-
Points are awarded as follows:
| Outcome |
Points scored |
| Win single | 1 |
| Win gammon | 2 |
| Win backgammon | 3 |
| Lose single | ½ |
| Lose gammon | ½ |
| Lose backgammon | ½ |
| |
| Win by timeout |
at least 1 |
| Lose by timeout | 0 |
Tie-breakers
-
In the event of two players tying for a place, the head-to-head result
is the decider.
-
If there are three or more players tied for first place and no winner emerges
from the head-to-head results then a mini-TTT will be played to decide between
them.
Timeouts and resigning
-
It is important that under no circumstances should you time out.
You can let all your other matches time out but not the TTT ones! ;-)
-
If a player times out then I will evaluate the last position's percentages
with GnuBg 2-ply and apply the TTT equity calculation to the opponent's
percentages. That equity will be increased by half a point, rounded to the
nearest tenth of a point and finally subjected to limits (a minimum of 1
and the maximum of the score for a backgammon). This value will be the score
for the match. There are examples
on the TTT Info page.
-
A player who times out in too many of their games may be removed from the
tourney.
-
Resigning has the same effect as timing out. You should never resign a
TTT game.
The small print
-
The Tournament Directors reserve the right to amend these rules in any way
that circumstances may require.
