Match Play. Red trails 0-5 to 7. How should Red play 63?
Red wants to wrap up the gammon, and the best way to do this is to make a six-point prime as quickly as possible.
Red has little to fear in this position and although it is close 21/15, 6/3 is the best play. 13/7, 6/3, with the same idea is the second-best play. The gammon percentage is very high, of course, but note that White will win this position 15% of the time. You’d really hate to lose this one as Red!
