Match Play. Red leads 4-0 to 7. Should Red double? If doubled, should White take?
For money this is obviously double and pass. At this score Red should consider whether he is strong enough to play on for an undoubled gammon. The answer to that is not quite, mainly because of White’s 2-pt anchor. However, Red is strong enough to double.
The second question is can White take the double? The answer, perhaps surprisingly, is yes and comfortably. Because of the score Red is, in fact, only just strong enough to double. White would blunder by dropping. He has the 2-pt anchor and all his checkers in play. In some variations he can create his own prime. The other key point is that he will be redoubling very aggressively.
So, close double and easy take.
