Game 2 (0-2)

In this post, I'll discuss the differences between my Nactation sequence of game 2 (shown above) and Storm's sequence of the same.

21$-65R-52P-21D-21$-41


2O ' ' ' '5X '3X '1X '3O

1X '2O '1O3O '2O ' '2O5X


White rolled 41, and there are two main ways to nactate her play of 24/20* 10/9. My choice was B (Both), moving one number on the far side and the other within the outer board.

Storm's choice was H (Hit), with the other half of the hitting play, by convention, being played "down" (to or within the outer board).

Both B and H require the 6pt convention for the ace (in outer board, the farther destination trumps). H requires either knowing the down convention as well (otherwise 6/5 would be the default) or using assumption; OTOH, H is a better-known letter. I see this as a close tradeoff, selection of B or H being a matter of preference.


2O ' ' ' '5X '3X1X ' '3O

' '2O '1X3O '2O ' '2O5X

...41B-52


The proper Nactation for bar/18 is U. Storm used R, which is admittedly supported in the Nactation tutorial but has become outdated. R must now include a destination between the 17pt and 13pt. Here you can find some links to the R/U clarification. (There have been other references since.)

As there is no legal R play in the position, one can "get away" with using R for bar/18; the closest destination to the 17pt-to-13pt area is the 18pt, and "running" is not an unreasonable way to describe the play. Positions do exist, though, for which the R/U distinction matters.


2O ' ' ' '5X1O3X1X ' '3O

' '2O '1X3O '2O ' '2O5X


Hitting in this position seems strange. However, this post is not concerned with strength of play but rather with Nactation, and Storm's areal letter of O (Outer) is a great choice for 13/7* 9/6.

I chose the style letter T (sTack/Tower) even though it points to only half of the play (with the hit convention taking care of the 13/7* hit). If 9/6 did not stand out so clearly as the only sTacking portion available, I would have gone with O, and even as it is I'm fairly ambivalent. Also fine is L (Lift).


2O ' ' ' '6X1X3X ' ' '3O

' '2O '1X3O '2O ' '2O4X

...63T-62


For the obvious move of bar/23 24/18*, I'm about equally disposed towards my given choice of H (Hit), and U (Up). As Storm and the rest of you know by now from my earlier explanation (under the diagram before the previous one), R is inappropriate but it is unlikely that its intended meaning will be misconstrued.


'1O2X ' '5X2O2X ' ' '1O

' '2O '2X3O '2O '2O2O4X

...62H-41@-33B-53P-54


For Blue's play of 13/4, another close choice of Nactation emerges. Storm selected the reliable areal letter of O (Outer) while I went with the stylish $ (Slot). Another option is numeral 4. Any of the three works well.

Similarly (see below), for White's play of 13/4 (with 63) three rolls later: Storm chose O while I chose $. Again, any of O, $ or 4 is fine.

...54$-64P-65R-63


'2X2X ' '4X2O1X ' '1O '

Next...


'2X2X1X '4X2O1X ' '1O '

' '2O1O2X3O '2O '2O2O3X

...63$-31


For White's play of 18/17*/14, Storm chose P (Point); no problem with that. I slightly prefer R (Run) as it can be grasped more quickly (IMO). Of course, either P or R requires the hit convention. (Without it, P would mean 8/4, and R would mean the hitless 18/15/14.)

A third possibility is H (Hit), which utilizes the more points convention for patching in the other half of the play (17/14).

...31R-64


'2X2X1X '4X1O ' ' '2O '

' '2O1O2X3O '2O '2O2O3X


For White's play of bar/21* 13/7*, Storm used the style letter K (Kill), which I prefer to the areal letter S (or Z).

Noting that there is only one way to play the roll, I elected to list just the roll (64) and omit the third character. Is this me being too minimal? Perhaps.


'2X2X1X '4X1X ' ' '2O '

' '2O1X2X3O '2O '2O2O2X

...64-43


Storm demonstrates his knowledge and flare by using 43< (enter one checker) to describe White's roll+play. Personally, I prefer to save two characters by listing just the entering number 4.

Mike didn't submit his Nactation for this game (at least not yet) but I suspect he would choose to list the roll (43) without the play (which is forced). This approach is also valid.

...4-65


'2X2X1O '4X1X ' ' '2O '

' '2O1X2X3O '2O '2O2O2X


For White's 65, Storm chose the areal S (Split and down). I do not fault S at all, though I slightly prefer the stylish P. (In the underlying definition of P, the entire roll is used to make a Point, but the entering portion can be waived.)


'2X2X1O '4X2X ' ' '2O '

' '2O1X3X3O '2O '2O2O1X

...65P-62


I omitted the roll (I don't care what it is) and just used "F" for fan. Mike would probably include the roll (62) and omit F, which is also acceptable.

Storm typed 62F, though I'm guessing he'll switch to 62^ now that he knows/remembers that ^ (the symbol pointing upwards, towards the roof) means to fan.

...F-66


'2X2X1O '4X2X ' ' '2O '

' '2O1X3X3O '2O '2O2O1X


With White's roll of 66, Storm correctly identified the play 13/7 7/1(3) as O (an O-type play with 1:3 ratio. I'm comfortable (naturally) with underlined families, but I (Nack the minimalist) chose to omit the O because the play is forced.

...66-55B-54


3X2X2X1O '4X ' ' '1O ' '

' '2O1X3X3O '2O2O2O2O '


For White's roll of 54, Storm's I (Inside) is the proper Nactation. Once again, though, the play is forced and I elected to include only the roll (also a proper choice).

After White plays 54, Blue cubes and White passes. Storm, who seems to prefer three-character designations for every roll+play, chose to end the game with "dbl-pas," while I chose the more standard "C-P." It is also reasonable to omit the C. (It is less reasonable to instead omit the P, as the reader might wonder if he is being quizzed on the cube action.)

Again, the game sequence is

21$-65R-52P-21D-21$-41B-52U-63T-62H-41@-
33B-53P-54$-64P-65R-63$-31R-64-4-65P-
F-66-55B-54-C-P

The experimental version of the same sequence is

21$65R-52P21D-21$41B-52U63T-62H41@-
33B53P-54$64P-65R63$-31R64-465P-
