You didn't say if we're playing standard carding (rightside-up C&A) or UDCA.
If upside-down, then partner has signalled that he started with
2 diamonds, and so I think we're in a world of hurt as defenders. Declarer then started with 3
♦ and has the
♣King in dummy for an entry, and I don't think we can stop him from taking 3
♦ tricks. So in this case, I might do something really desperate. But maybe not....
If rightside-up OTOH, then partner started with 3 and declarer started with a doubleton
♦, and the
♦3 is missing, and partner has it. Thus his second
♦ play -- an unnecessarily high one -- is a signal. Playing with my regular partner I would interpret it as showing strength in
♠. On the bidding, he (partner) must then have the
♠Queen (and declarer the King of
♠).
{nb -- I suppose it's possible for declarer to have fudged a bit with a 5-card club suit and bid this way with the
♠Queen instead, and partner has the
♠King and is so signalling, but I don't think I need to count on that.}
All I need to know is, that if we're playing rightside-up signals in the count, then the
♦ are dead. Declarer's out of
♦ now, and has just the
♣King as an entry to dummy. Partner has the
♠Jack guarded so declarer can't get there in
♠.
But I don't know which way we're signalling, so I can't decide.
