Hi everyone,
I still use the mat-format frequently to archive matches. I just
recognized a bug of gnubg (both 0.15 and 0.16) when exporting matches
into mat format under the following condition:
One player still has some chances, rolls his dice, doesn't roll the
required rolls and resigns after rolling without having moved his
checkers. The sgf-file will contain the rolled dice and the resignation.
The exported mat file however does not show the rolled dice. Instead the
mat file will contain the dice and moves done by the _other_ play before.
Here a little example from a match of this year's World Championship
(thanks, ace):
That's how game 1 was actually played. After rolling 41 player BLACK
resigned in game 1:
17 point match

And that's how the match file looks after having been exported from gnubg:
17 point match

32) 63: 4/0 3/0 32: 20/18 9/6
33) 22: 4/2 2/0 2/0 2/0 31: 19/18 13/10
34) 32: 3/0 2/0 52: 18/13 13/11
35) 32: 3/1 3/0 52: 18/16 11/6
36) 65: 1/0 1/0 65: 1/0 1/0
Wins 4 points
Game 2
WHITE : 4 BLACK : 0
1) 35: 8/3 6/3
2) 65: 24/18 18/13 41: 24/23 13/9
3) 41: 6/2* 2/1* 62: 25/23
So instead of 41: the last move in game one of player BLACK is displayed
as 65: 1/0 1/0, the repeated move of the other player.

Hardy ;-)
