Hello, I'm new to the group. Now finding a renewed passsion for BG. I was 10-12 when it was all the rage in the early 70s and my father paid a premium on our stakes so that I would sit down and play with him. Very fun to learn how the approach haschanged since, more conservative and safe.
I'm looking for any help in understanding the reason for the proper play in this position.
Thanks,
Bob

Thanks, Paul. Sorry about that. I didn't double check that XGID. Had a similar problem once before.a prime, to have more than one spare on any made point. But I feel like I'm missing something more important and instructive.....
My play was 13/9 13/10. My best guess, from the correct play, is that it is better to start forming inner board points sooner in case you start to have an exchange of hits. My more abstract idea is that it is inefficient, when trying to build and move

But now I'm confused on another issue. Why would attacking play for a gammon rise well above the priming play in the match situation where the gammon value is (50-43)/(43-26)=0.4, as opposed to a money game where the gammon value is 0.5? I would havethought the play for a gammon would be more favorable in the money game.
I would have played 7/3 6/3.
Compared to 13/10 13/9 it makes an /additional/ point, not merely
/shifts/ an existing point to a (better) position. It is also an inner
point, which helps when the priming battle due to timing constraints has
to be turned into a blitz.
Compared to 8/4 7/4 the 3 point is slightly weaker, but avoids the 6 devasting tempo hits.
As a newcomer to the group, I'd appreciate it if somebody were to guide me to the etiquette page. I'd like to continue to post questions to learn from your comments, but I certainly don't want to become the horsefly at the picnic. If I post too much orpose too amateurish questions, feel free to swat, or just gently shoo me away.
Thanks, everyone, for really helpful comments.pose too amateurish questions, feel free to swat, or just gently shoo me away.

I would have phrased this differently. The distinction between an
additional point and a shifted point applies to 8/4 7/4.
13/10 13/9 technically "shifts" a point but it took me a few seconds
to realize what you were talking about

BobWhat are you learning about division rings? Are you familiar with this: https://www.cambridge.org/core/books/skew-fields/F1E585F236E4E10350AAA8D9A3CF66AE
Is this a research topic for you, or are you trying to get a feeling for how field theory transfers to the non-commutative case?
I doubt that there is an etiquette page. I think all questions by you will be welcome.
There's a pretty low bar here because a fair amount of posts (I didn't say posters) consist of blatant trolling and etiquette breaches.
As for myself, I post a fair amount of backgammon content, but I also post stuff that is wildly irrelevant like an anecdote about not understanding
the menu in a German restaurant. But even the wildly irrelevant stuff is ok. Axel seemed to enjoy my post about the German restaurant.
I think it's generally an etiquette breach, almost everywhere in netland, to ask questions which are readily googlable.
So I don't think a question like: "What does DMP mean?" is completely appropriate because it just wastes time -- the
answer is just to type "DMP backgammon" into your google search bar.
Such a question would be a bit like asking what 59 * 509 is. The answer is "Use a calculator" which is a bit like saying "Use google."
The reason I'm banging on about this particular non-googling etiquette breach is that, judging on your first few posts, it's the only
etiquette breach that I can imagine you committing.

That was a weak attempt at self-deprecating humor, like: "BG has
changed so much since the 70s that there is something called a
division ring that I now need to learn about".
I appreciate your sincere interest helping me with math
After I read the word "tensor", I didn't think years of a cloistered study of math and physics would end well for me, emotionally or physically. So now I watch science programs on TV and am content.

understanding of what a tensor is. On the StackExchange for
physics, I gave an explanation of one of the simplest examples
of a tensor, namely the moment of inertia tensor.
https://physics.stackexchange.com/a/676228/
The mathematics, as well as the physical intuition, does get
more difficult when you have to deal with not just a single
tensor, but a tensor *field* (just as a vector *field* such as
an electrostatic field is more complicated to deal with than
a single vector), especially in something like general relativity
where you have a tensor at every point of a spacetime manifold.
Still, it's ultimately the same basic concept: a tensor is
something that describes a multivariate linear function.

the history of the known universe.
In fact he wrote a major research paper on the topic.
A non-contact position is the same as a "pure race".
I think that's what he meant.
There's a strong intellectual power centre on this forum,
and I certainly don't feel part of it. I can only hope to
read and be inspired.

Wait, don't answer that! Sometimes an unanticipated discovery is just what it takes to make your day. I'm going to wait for that moment.

I thought he intended a double entendre. My apologies, Axel.
