Opening Rolls

 Nactation--Why use it?

 From: leobueno Address: leobueno@usa.net Date: 16 January 2011 Subject: Why use Nactation? Forum: BGonline.org Forums

```When I first began reading about backgammon, the conventional notation
seemed fairly intuitive. I see that in this forum several folk use

I started to try to figure out Nactation but that got me thinking: Given
the accepted and widespread use of conventional notation, why does the game
need a new notation system?

I realize Nactation is more economical, however, it does not feel very
intuitive (this of course may just be a case of an old dog learning a new
trick). Also, as the original subject of this thread indicates, Nactation
appers to engender some notational ambiguity. Since the old approach is
good as it is, why use a new one?

By the way, I am sure that I speak for everyone in the forum when I express
my gratitude to Nack for his ongoing contributions. I hope he accepts the
spirit of this post, which in no way is intended to antagonize or criticize
Nack for promulgating and advocating the use of Nactation.

However, for the opening moves, Nactation is an excellent system. Within the first few rolls, the types of plays are rather standard: slot, split, reverse split, builders down, hit and down, hit and split. Nactation (once you've learned the few basic symbols) gives a nice way to describe the numerous openings with the more intuitive, conceptual, and descriptive "split" instead of the less intuitive, though no doubt more familiar "13/11 24/23". ```

 Tom Keith  writes: ```Nactation is really designed for opening positions. You can picture an opening position by visualizing the moves that take you there. Because nactation is based on concepts (such as "slotting" or "splitting") it is a good system for visualizing moves and the positions they produce. Also, nactation is terse, so it makes convenient "names" for discussing positions and good filenames for containing rollouts. ```

 Stick  writes: ```The honest reason why your standard backgammon player should become at least familiar with the basic components of Nactation are that they read these forums (http://www.bgonline.org/forums/) and want to understand all the free world-class advice that is being put out there by people like Nack, David, Neil, etc. The real question is why do these people, the Nacks, Neils, and Davids of the world, use Nactation? As leobueno aptly noted in his question, conventional notation is intuitive, understood by all, and easy to learn so why do we need a new system? A few of us love this new system for many reasons. Nack, probably in his journey to write his Backgammon Openings series, created a clever system that would allow one letter or symbol to stand for how a roll was played. This affords us the possibility to: * Keep file names short with meaning. For example, I have literally thousands of opening phase of the game rollouts, how would I know what is contained in each file without Nactation? Would I have names like "Second roll 6-3 after opening 5-4 splitting"? What a mess of file names that would be. You know what isn't a mess ... 54S-63. Right there in those few keystrokes I've summed up how the first roll was played. If I tried to use old notation in file names you can imagine how rough that would be. 54-24/20-13-8.63 or something of the sort? Sick. * Since I also have a web site and exchange an endless amount of emails with players also discussing the opening or linking to my opening rollouts, it makes my links and the discussion much crisper. Again, we have a way to describe precisely what is going on and save a ton of keystrokes and confusion. * I don't think Nack had this in mind when he was creating it but, tough break, can't go back now. I use Nactation when I'm hand recording matches on paper. This makes it sooooo much faster and saves sooooo much garbled writing. This takes a certain level of competence with Nactation but once achieved you'll never turn back to the way of the old. If I'm watching a match and I want to note down an opening sequence to check later or even if I want to record the entire damn game without the players involved knowing (mwhahaha) I can act like I'm texting on my cell phone and using your basic notepad put the game in as they play without missing a beat. You wouldn't be able to do that with standard notation. * By combining Nactation with Nacbracs we're able to keep a lot of data in a short amount of space and avoid having to open files to extract it. For example, let's say I wanted to get across to you the results of an opening 54 played 24/20, 13/8 and the candidate plays of a 63 reply for money. There are 3 candidate plays, 13/7, 8/5*, 24/18, 8/5*, and 24/15. Now if I was typing out all of the that I could type that 13/7, 8/5* is better than 24/18 8/5* by .014 and better than 24/15 by .021. See how messy all that looks in comparison to: 54S-63 [H X14 R21] /15 In my line I was even able to include what bot it was rolled out with, identified by the forward slash, /, and how many trials denoted by '15' which represents 15552 trials. This may look oddly foreign to you in the beginning, and that's why Nack includes a key in all of his posts. This is such a better system and really doesn't take that much work to become accustomed to understanding it. There are secret uses of Nactation that few but the true junkie will know. For example, about two weeks ago I went to my weekly trivia night and one of the questions was 'Where is the '\$' symbol found on a keyboard?' Nobody in my group of people was sure and I can't say for certain if I would have been even though I am on a computer 24/7/365 without Nactation. That slot symbol is at the number 4 key and I could never forget it. Thanks Nack, I think we took 13th place out of 30 or so teams with your help. Nactation was originally developed to describe the opening phase of the game. It has developed into a full system that can be used to nactate entire games if you're familiar enough with it and sick enough to do it. There is no ambiguity for 99.X% of the plays involved. It's all a matter of how well you know it. It has to be learned but is also very intuitive once you get the basic symbols under your belt. If you have any problems all the experts are hanging around here to help answer your questions.

Nack has also mentioned recently that he is working on an update to the tutorial that many I'm sure are salivating over. ```

There are some things I do not like about it. * I really hate the fact that nactation isn't well-defined, and even worse, there are codes that only a select few seem to know. It seems like about once a week, there's a post from somebody about how to nactate something or other, and invariably, I find out that the correct symbol to use is "]" or some such nonsense. It isn't made up ... it's part of nactation, but nobody's bothered to tell me until now. I hate that crap. Maybe this update to the tutorial will help matters, but for now, nactation seems like something where I can't become a black belt because the big bosses are carefully guarding the inner sanctum. * It's a barrier to entry. I can almost guarantee you that most beginner/intermediate types are going to see all the S, \$, D, B, C, U, blah blah blah and wonder what that nonsense is, and will think that it's too hard to understand. It serves to stilt growth amongst the very group of people who need to understand more. * Nactation for hand recording is only useful if you're just doing it for yourself. And I'm never going to do it that way. * I don't like all of the brain power I need to use to try to remember the difference between E and O and N ... yeah, yeah, I know it's not rocket science, but I have a hard enough time with backgammon, now I have to learn a semi-cryptic notation? Ugh. I do very much appreciate the shortening of file names, of shortening discussions, and of encapsulating a lot of information with nacbracs, and I appreciate the fact that it's now a part of the game, and if I want to keep up with the big boys, I need to know at least the rudiments of nactation. Keep in mind that this is just a criticism of specific things -- for the most part, I'm on board. ```
