Analysis in accordance with my paper "Take Points in Money Games" equations 8, 9 and 10 is given below:
Consider the positions for unlimited games without Jacoby (using XG R++) evaluations:
For the Blitz Position: W = 1.522, L = 1.208, X1 = 0.719, X2 = 0.696. These values are derived from XG R++ equities where either side owns the cube. Without knowledge of the actual cube-centred equity, these values may be plugged into equation 10 to give an estimated value of 0.706. This compares very well with the XG R++ centred cube equity of 0.702.
For the Deep Contact Position: W = 1.561, L = 1.188, X1 = 0.797, X2 = 0.830. These values are derived from XG R++ equities where either side owns the cube. Without knowledge of the actual cube-centred equity, these values may be plugged into equation 10 to give an estimated value of 0.719. This compares very well with the XG R++ centred cube equity of 0.722.
Although the two positions have very similar cubeless equities, the cubeful equities diverge significantly because cube ownership (leverage) value is much higher in the more static and less volatile deep holding game (about 80% efficiency) compared to the more dynamic and more volatile blitz position.
This general relationship applicable to unlimited games will also apply tend to other match scores, skewed or otherwise, providing that the cube retains some significant value.
