 Crawford game double

 From: Raccoon Address: racgammon@yacannedmeathoo.com Date: 30 September 2003 Subject: Crawford Rule news Forum: GammOnLine

```The Danish Backgammon Federation's Tournament Committee has published
an interpretation of the federation's Crawford Rule.

Paragraph: 4.4.4 4 The Crawford rule applies in all matches. In the
first game in which one player needs point to win the match, neither
player may double. If a player nevertheless doubles, the doubling is
annulled. In following games, if any, the doubling cube may again be
used.

Interpretation: Doubling in the Crawford game is illegal, no matter
whether the leading or trailing player doubles. Any doubling is
annulled so long as the next game has not begun or, when the game in
which the doubling occurred ended the match, so long as the result has
not been recorded by the tournament leader. The tournament leader is
obligated to intervene, if he becomes aware of a doubling in the
Crawford game, and annul the doubling. When the doubling is annulled
in an ongoing game, the players shall continue the game without using
the doubling cube. When the doubling is annulled (1) between two
games, or (2) after the game in which the illegal doubling occurred
ended the match, but before the result has been recorded by the
tournament leader, the players' scorecards shall be corrected, such
that the number of points gained is that number which would have been
gained if there had been no doubling.

If the players don't realize it was the Crawford game until afterwards when they try to score the game - which is the most common time for this error to be discovered - just score the game as if the cube had not been turned, and move on. If someone wants to say they would have played differently had they known the cube was on 1, tough rocks. ```

 Chuck Bower  writes: ```In other words: "do two wrongs make a right?" A director could use his/her discretion here. If match leader should know better and is possibly trying to pull one over on a novice opponent, I would expect the ruling to be "restart the game; cube is dead." If between two novices, neither knowing better, still probably the correct ruling. ```

Is the wrong win erased, and a new Crawford > game started I asked one of the Committee members, and his offhand opinion was that the point should count. Which is reasonable, if not consistent. There's a limit, generally, to how much ought to be undone to correct an illegality -- an error in setup stands if not corrected before the Nth roll; an illegal play stands if not corrected before the next roll. Replaying an entire, completed game is quite different from a simple adjustment to the score. I think I'd tend to agree with Chuck, though (if this is what he thinks), that (1) having the game be replayed might often be fairer, that (2) the decision might best be left to the director. ```
