Match Play. Double Match Point. How should Red play 63?
This is a pay-me-now-pay-me-later problem. The choices are 15/6 or 8/2, 4/1. Note that 15/12, 15/9 is a double blunder, leaving White with very few poor numbers next turn.
The correct play is 15/6, paying now while White has a blot in his home board. If you move the White blot from the 6-pt to the safety of his 4-pt then 15/6 becomes a blunder as White will have so many bad numbers next turn and Red should play 8/2, 4/1.
As usual, attention to detail is key in making the right decision.
