It is very unlikely that the sequence I listed above is what actually happened (though only Jason might know). I aim to keep my retro-sequences as short as possible (which explains why there were so many doublets here). In short, if I were a betting man, I'd bet that the real-game sequence was longer.On the other hand, when humans misplay, their sequence is sometimes shorter because it does not conform to my self-imposed standard of "well played" (no error worse than .02). For example, it takes me an extra roll to reach 52$-43Z-xx because of the misplayed opener. My shortest solution would be 43Z-52H-31H-xx.
The sequence in the caption of the diagram reaches the position in 22 rolls (Blue's 32-to-play being the 23rd). However, if strong play goes out the window, it is possible to reach the position in 13 rolls:
........54D-41B-33D-21H-44K-31-22K-31-334-11Y-4-33O-33E-32
For those not fluent in Nactation, the moves that are not "well played" are marked in red. In order, they are 24/20 8/7, 13/7 8/5 6/3*, bar/21 9/3* 5/1*, and bar/22 13/4. [XG++ doesn't think that (the unmarked) 33E (bar/22*(2) 6/3(2)) is worse than -.02, but I suspect it is worse, which is why I did not use it in my original sequence.]
After 11Y, Blue suddenly becomes too good to double. Therefore, cube for Blue anytime before he rolls 11, which is early, but at least the take is correct. Or if you want the double and take to be correct, replace 21H with 33Z (bar/22* 13/10 13/7, blunder), and 33O with 21I (6/3*, correct), and insert "C" (Blue cubes) before 11Y.
