I would cash the diamond A
What is the advantage of cashing the
♦A?
When we ruff the spade high, either opp could pitch a stiff diamond: yes, it is extremely unlikely, but I don't think that guarding against it is ever going to cost... it's not as if we are worried about an extra undertrick. And if it happened, we'd be in dummy with no way back to our hand, so we'd have to try to cash the diamond Ace and it would be ruffed.
Technically speaking, I think the diamond Ace play might cost, in theory.
Suppose you win the spade lead, cash a high trump, and then run down three hearts, but LHO ruffs the third heart. With nothing left to do, you overruff.
Suppose further that this RHO started with 7-2-2-2 shape, with the Q9 or K9 in diamonds.
You now pull the last trump out, ending in hand and preserving transportation to dummy. You now lead the diamond Jack.
If LHO plays the 9, you float this. If RHO wins, he cannot return a spade; whatever he returns, you lead a second diamond to dummy and claim. If RHO ducks, you repeat, overtaking to lead diamonds, eventually claiming the overtrick.
If LHO covers, you overtake with the Ace and lead small toward your hand. If RHO pops his honor, he cannot lead a spade, so you will win whatever, cross to dummy, and claim. If RHO ducks, you lost no diamonds. So, you just give up a spade to LHO and then ruff out the last spade.
Seeing as this is too sexy for words, you just have to leave that option open, you see.
