If declarer has AKxxx of spades, he can just ruff 2 heart losers and throw the remaining rubbish on the diamonds, even if partner has the CK (as indicated by his D7).
So it seems we have to hope partner has the SA or SK. If he has the SA we can potentially beat it by playing a low trump. Partner returns a diamond and we get a ruff or trump promotion.
However, I'm not sure there's a need to hurry. If we take partner's D7 as a genuine suit preference signal, he has the CK, so we just play a club. If partner does have SA then, since declarer can't run the diamonds without drawing trumps, we win as above. If partner has SK, after SA - heart ruff - DQ we ruff in with the SQ and play clubs.
I always miss something though...
