NG Opening 21

In Response To: Nackgammon Opening Rolls (Phil Simborg)

Does anyone have the opening rolls for Nackgammon?

Paul Weaver did a lot of Nackgammon rollouts -- all the openings and a few responses -- in the late 90s / early 00s, all on Jellyfish and/or Snowie-3(?) and many or most rerolled on Snowie-4. I lost a lot of files in my crash of 2005, and Paul might have lost his copies in a crash last year. Fortunately, I kept all (or almost all) the data in MS-Word docs in nacbrac form (I never would have spent the time to transcribe them with traditional notation).

In addition, thanks to Stick's and Ken's help, I now have lengthy Nackgammon opening (money) rollouts with Gnu, and Ken is in the process of rolling them out at DMP, GS and GG as well.

It is clearly correct to make an (offensive or defensive) point with opening 31 61 65 43 42 32, and the strength of the top six rolls are ranked in that order. (Yes, 61 is better than 42.)

Compiling the (currently disorganized) rollout results would be some work, but I'll be happy to do so if there is significant interest. (If there are enough respondents, maybe Tom Keith will even add the stats to his site.) I'll do one roll at a time and see how it goes.

How do people play opening 21? The starting position of Nackgammon is shown below, for reference.

Feel free to opine how good and bad alternatives are, as well.
