Another confusing one, where I almost nexted this - and then found making the 5 point is NOT coming up as the best option - any thoughts on why?

Why indeed - maybe Gnu was having a hissy fit?  According to Bgblitz on 3-ply, making the 5 point is by far and away the strongest play, with 9/8, 10/4 as the next best, at -0.043.

0 ply rollout prefers to make the 3 point.  I have no idea why.  I'm inclined to think that gnu is somehow mishandling this position. Steifnu says that bgblitz prefers making the 5 point, but he also say that it thinks 10/4 9/8 is better than making the three point, and I find that difficult to believe so I'm skeptical of bgblitz's result.
Ooops, my apologies - no wonder it was hard to believe, I had a chequer misplaced.   :blush:

Bgblitz 3-ply analysis is now much the same as the gnu 2-ply rollout and likewise favours making the 3 rather than the more obvious 5 point:
1.   1. 0.876 mwp /  0.387           4-3, 9-3
2.   0.870 mwp /  0.354 (-0.007)  6-5, 11-5
3.   0.819 mwp /  0.102 (-0.058)  9-8, 10-4

Well, a great position indeed. Thank you Diane.

I think that the main consideration here, as other fellow fibsters pointed out, is the 'building opportunities'. After making the 5-pt, our resources to build the 3-pt and close-out will be depleted as the checker on 10-pt is 7 point away from the 3-pt and thus, 'out of building range'; while if we opt to make the 3-pt first, this won't be the case as all of our men will be in building range.

About the 'strategical' importance of the 5-pt, I think we should not exaggerate significance of the so-called 'golden point' too much. Yes, it's good to make your 5-pt, but 'early' in the game and not during a blitz or pre-close-out period, as during these last stages having a 'prime' is of least value. During blitz/close-out, the most important thing to consider is to not allowing your opponent to make an anchor, especially in your 'deep' points. And if by any means, we're forced to let our opponent making an anchor, let him make an 'advanced' anchor as you'll have less hassle bearing-off your men against an advanced anchor than when facing a deep anchor. Correct me if I'm wrong.

Just my 2 cents...

The leftist's feelings of inferiority run so deep that he cannot tolerate any classification of some things as successful or superior and other things as failed or inferior. This also underlies the rejection by many leftists of the concept of mental illness and of the utility of IQ tests.  - T.K
