    Money Play. Should Red double? If doubled, should White take?

    This is prime against broken prime. IS the threat of rolling a 4 enough to give Red a double?

    The answer is not quite although it is close. Certainly Red is the favourite but he does better to hold the cube and await the opportunity to give White a much more difficult decision later.

    Doubling is technically an error.

      Red has a better prime, but his timing is worse. ND/T.

      ND/T. Can't see many market losers for red, at least not the 9 I require for a double.

      I am currently doing a study on Cube decissions according to volatility.This is of moderate volatility and you need a clear advantage to double. To decide the advantage you have to go through all the rolls. Here the running 4s (5/36) are great rolls assuming we won't get hit.More or less get offset by opponent's 13,33 and 22. The remaining splitting 4s are also good assuming we won't get hit with a 3, plus the splitting aces. Opponent's splitting 2sare also good assuming he doesn't hit back with 3 or 5.

      To make a long story short I figured that he doesn't have enough advantage to Double.

      ND/T

      Actually the 9 MLS may only apply in non volatile positions. To be precise you need 324/1296 sequences. At such positions you may need >400 meaning more than 11 to double.

      Now imagine the back checkers were allready split say one checker was at 23 or at 20.

      What do you think would be the Cube decission in each case?

      White's open 5 point is significant. D/T.
