Nice pecs, storm. You did very well!

51S-54S-61P-33A-32@-61R-62F

or in classical notation: 5-1 24/23 13/8, 5-4 24/20 13/8, 6-1 13/7 8/7, 3-3 8/5(2) 6/3(2), 3-2 24/21 23/21, 6-1 20/14/13, 6-2 13/7 8/6

51S-54S-61P-33A-32@-61R-62F-44

Many letters that move checkers in the back quadrant can be more broadly applied to the entire far side. (I've mentioned this in past posts though it isn't yet in the tutorial.)

For White's roll of 44 played 24/16 13/9(2) in the above diagram, I like B (Both). You used R (Run), with the assumption of 13/9(2) for the other two 4s, which is okay, but B is clearest.

Regarding Blue's previous move of 6-2 played 13/7 8/6, your "F" (Float the spare) is fine. I have a slight preference for O (which defines both halves of the move with the greatest clarity). Other good choices are T and 6.

44B-33C

classical notation: 4-4 24/20/16 13/9(2), 3-3 21/18(2) 8/5(2)

51S-54S-61P-33A-32@-61R-62F-44B-33C-32

storm: The play was 16/13 6/4. After lifting the blot, 6/4 seems clear, so I chose 32L for this play. Is there something better here ?

Nack: Yes. By the same logic that supports 44B for White's last play, E (Each) works best for 16/13 6/4 here.

You can certainly get by with assumption here, and Stick is right that when using assumption it is better to nactate the less obvious portion of the play when possible. Lifting 16/13 is more obvious than slotting 6/4, so \$ (or 4) is better than L, though L is passable.

32E-43P-43O-65D

classical notation: 3-2 16/13 6/4, 4-3 7/3 6/3, 4-3 13/9/6, 6-5 13/7 13/8

51S-54S-61P-33A-32@-61R-62F-44B-33C-32E-43P-43O-65D-65

storm: The play was 13/8/2. First I wrote this as 65O, but I guess, strictly speaking, this should be 65o using the closest to the 6-point convention ?

Nack: Right; good thinking! Employing the assumption that White wouldn't volunteer a shot, O should be fine (I wouldn't be critical of it), but I prefer the (lower case) o because that works even if the interpreter applies strict usage (which is O = 13/8 9/3, and o = 13/8/2).

Assumptively, \$ should also be fine. For strict usage, \$ (slot) means 8/2 9/4 and % (alt slot) means 13/8/2 (the 4pt and 8pt are equidistant from the 6pt; tie goes to the lower point), but I wouldn't worry about it as it's hard to imagine someone volunteering a single shot let alone a double shot. By the same logic, the italic 2 conforms to strict usage, though the non-italic 2 is surely sufficient.

65o

classical notation: 6-5 13/8/2 (or 13/2)

51S-54S-61P-33A-32@-61R-62F-44B-33C-32E-43P-43O-65D-65o-21

storm: Here 6/4 6/5 was played. Writing 21\$ would show that the 4-point was slotted and not by playing 7/5/4 since, using the unstack the largest stack convention, that play would be nactated 21%. So the problem is to indicate that the ace is played from the 6 point as well if we assume this is not obvious. Is there a sign used for unstacking (inverted T, T with a dash through or similarly) ? Or maybe this is where you stop annactating, knowing that nactation was primarily meant to be used in the opening ? :o)

Nack: The unstack-the-tallest-point rule applies to the slotting portion of the move. Having slot the deuce, the ace conforms to the 6pt rule: therefore \$ = 7/6/4 and % = 6/5 6/4. (With most audiences, though, I think you could slide by with \$ for the latter more natural move, on assumption.)

storm: If you do continue, how would you nactate white's following 3-2 6/4 5/2 ?

Nack: I would rely on the reader assuming that no direct shot will be left here. With that assumption, 4 means 6/4 6/3 and the italic 4 means 6/4 5/2. In short, I would use 4. (For a strong audience, you could arguably use the non-italic 4, though that's further than I like to take assumption.)

Yes, Nactation is primarily intended for early game moves. You can see it through to the end of the game, though truthfully I haven't spent much time on developing rules for late board-shuffling positions.

Your game sequence, again, is

51S-54S-61P-33A-32@-61R-62F-44B-33C-32E-43P-43O-65D-65o-21%-324

I underlined Blue's rolls (an optional convention) for clarity.

Cheers,

Nack
