Overcalling 2NT over 2♥ is far better, eventhough the suits differ a lot; diamonds are one card longer and has lots of intermediates. But you'll get the chance to raise partner's presumed club preference one level and help him evaluate his diamond holding at the same time.
And if it goes 3♥ p p you're still alive and can make another bid (preferably 3NT, I don't think double is correct then).
I'm still not confident that 2NT is the perfect bid, but it's absolutely clear to me that pass over 1♦ is 100% correct.
I agree.
I have belatedly looked at the thread and agree that partner should raise to 5♣. On the auction it is reasonable to infer that overcaller has, to some degree, relied on our having some modest values because the opps have bid gently. Viewed in that fashion, we might argue that overcaller has bid our hand for us, and so we shouldn't hang him.
But while our hcp may be in line with his expectations, he has hit a home run in terms of honour location: even the club 9 may be important (consider a hand lacking the diamond spots and therefore needing to take some ruffs in the K9xx hand. So we have to raise: as Harald says, aiming for 130 is shooting at a very tiny target.
