Onesided Holdinggame, Cubeaction?

I don't know if I've ever seen the 8/9/12 rule be wrong in low-wastage positions. Since the positions used in that article are essentially random (high-wastage) it makes sense that the 8/9/12 rule fares poorly. For example:





White is Player 2

score: 0
pip: 3
Money session
Jacoby Beaver
pip: 4
score: 0

Blue is Player 1
XGID=-D----------------------c-:0:0:1:00:0:0:3:0:10
Blue on roll, cube action?


Analyzed in XG Roller+
Player Winning Chances: 86.11% (G: 0.00% B: 0.00%)
Opponent Winning Chances: 13.89% (G: 0.00% B: 0.00%)
Cubeless Equities
No Double:+0.722
Double:+1.444
Cubeful Equities
No Double:+0.722 (-0.278)
Double/Take:+1.444 (+0.444)
Double/Drop:+1.000
Best Cube action: Double / Drop

eXtreme Gammon Version: 1.21

Saying that 8/9/12 recommends ND/T while other systems recommend passing is a little bit unfair.



Regarding the OP,

a holding game with a made barpoint by the defender should be evaluated pretty much as a pure race

I think this overstates the case by a substantial margin.
