Match Play. Red leads 10-0 (Crawford) to 11. How should Red play 22?
When I set this problem there was quite a difference in the top two plays on initial evaluation but on rollout three plays tie for first place. So long as you play 20/18(2) with two of the twos then you are OK.
The other two can be played 3/1(2)*, 10/8, 6/4 or 10/6 and there is no difference between those moves. So, this problem turned out to be rather easier than I had planned.
Of course, in a money game with White owning a 2-cube then you must have 3/1(2)* as part of your move to maximise your gammon threat.
20/18(2);3/1*(2) looks right to me.
