Money Play. How should Red play 66?
This is all about cube efficiency.
If Red plays 18/12(2), 9/3(2) White cannot take the impending double unless he rolls a big number himself. If Red plays 18/6(2) White will be able to take the double because of the possibility of hitting a shot when Red breaks the 9-pt.
Red does better in terms of maximising his equity by playing 18/6(2).
An instructive position because it teaches us something about how to maximise equity by taking a small risk.
