dorbel leads 4-0 to 5, Crawford game, and has a 5-4 opening roll to play. I'll take it I can skip the picture this time  :)

24/20, 13/8 is the standard play here and I'll go with that.

XG's opening book:

The split is probably correct, but at this quasi-DMP score running is interesting too. Two down is more of a gammonish play and therefore, most likely, inferior at this matchscore.

    1. Book        24/20 13/8                   eq:+0,030
      Player  : 51,00% (G:12,94% B:0,65%)
      Opponent: 49,00% (G:12,52% B:0,46%)

    2. Book        24/15                        eq:+0,022 (-0,008)
      Player  : 50,55% (G:11,13% B:0,48%)
      Opponent: 49,45% (G:12,62% B:0,43%)

    3. Book        13/9 13/8                    eq:+0,011 (-0,020)
      Player  : 50,10% (G:14,54% B:0,73%)
      Opponent: 49,90% (G:13,16% B:0,62%)

I knew that running 24/15 was close, but nobody ever plays it, don't know why! I never do. I often play 13/8, 13/9 at other scores though. It is technically incorrect but draws lots of mistakes with the replies.
