62R-44 — Nactation Key
FamilyNactationTraditional NotationNote
BothB 24/20(2), 13/9*(2) For a roll of doublets, B (Both) means playing 2 dice on the far side of the board, and 2 more down (i.e., to or within your outer board).
PointP 13/9*/5(2) In the P (Point) family, all parts of a roll must be used to make a single new point.

Explanation of nacbracs

Except for the fact that 62R is such a rare opening, Stick’s GnuBg rollout is close enough to warrant an update with XG.

This excerpt is taken from the last link, where a complete game is nactated and explained:

The P (Point) family has a Dedication Clause that requires that all parts of a roll be used in making one new point. Moves that make a point, and then move some other checker, cannot be nactated P. Neither can plays that add a spare checker to an already made point. It is, however, acceptable to switch points, or break one point while making another, so long as all parts of the roll are used in making the new point.

The only execptions to this rule comes when entering from the bar, and when part of a move is forced. So long as all unforced parts of a move are dedicated to making a single new point, the play can nactated P.

If you have a rollout of an early game position that you would like to share, please send it my way. I will credit you, and include it in the next release of my RolloutSummary.
