an edited hand from one that occurred earlier in the week, assumed IMPS.

 

Partner leads the King of diamonds, what do you play at trick one and why?

 

Not sure if this is forum appropriate but intended for N/B

 

Thanks

Requesting a ♠.

I'm hoping partner has the ♠A and I want to put declarer to the test at once.

I'm usually terrible in these situations, so this probably blows the defense. :)
