A pickup partner led the A. Could you explain the rationale please.
I ran this through Jack - Jack led the A so it's obviously OK. I thought that vs a suit contract you should not lead the ace at trick 1 unless you also have the King.

Its not unreasonable here. Most of the time, I tell people not to lead unsupported aces, but here it's got some play. Your side needs to get 4 tricks to beat 4, and partner can see the A and maybe the A. Where are the other 2? Partner is hoping to find you with a singleton heart, get a ruff, get back in with a diamond and give another ruff.

Or even just to see the dummy and figure out if there is any chance of one or even two diamonds tricks before declarer makes them disappear.

I would assume, that the Ace of diamonds is better.
The idea is the same, you want to have a look at dummy, and decide,
if you have to switch.
As it is, the Ace of diamonds is worse, because partner opened a weak 2
with a 7 carder, and the remaining diamonds are 3-0.
Given the vulnerability, the weak 2 is not bad, but the 7 carder is still
not the most likely holding partner will have.

With kind regards

I would assume the Ace of Diamonds is quite a bit worse, as given the X it's somewhat likely getting ruffed, and it's not that unusual for W to have the Kd here. Diamond preempts can be a bit suspect.

I think the real mistake here is to open 2. That's the kind of bid that destroys partnership trust. Open 3 or pass. By underselling the length you're impeding partner's ability to further the preempt considerably. Ax or even stiff A is pretty good opposite 7... much less good opposite 6.
