Match Play. Red leads 9-3 to 13. Should Red double? If doubled, should White take?
This is a huge double – not doubling is a quadruple blunder. A gammon (which happens 13% of the time) wins the match with perfect efficiency for Red. The position is hugely volatile and White is going to have to tiptoe through the tulips to avoid defeat.
It is also a clear take for White because of the possibility of redoubling to 4 and catching up in the match. Interestingly the match score has little influence; the doubling decisions and are exactly the same for money.
