I come late to this thread. I would prefer 1
♦ to 2
♣, altho the advantage of 2
♣ is that it immediately gets across the gf nature of the hand and the good support.
The problems with 2
♣ seem to me to be twofold: it compells you to be captain in this auction: no way can you later involve partner in an informed manner. You may be able to communicate your short (void)
♠ but you will never be able to show your true source of playing strength. The second problem is that your
♣ are so weak that you may have set the wrong trump suit. It is not so much that you may have losers in
♣ that you would not have in notrump or
♦ (you can usually get to nt is you need to) but that you may end up in a position where your own weakness in trump will dissuade you from bidding on. You will feel reluctant to make extra moves in a suit in which you have already forced to game on J10xxx opposite a holding that might initially have been xxx.
I think that on balance, starting 1
♦ will allow you more meaningful input from partner on many auctions.
However, having said that, the truth is that the interference by the opps (which is hardly a surprise) would probably have disrupted the auction anyway
So while I prefer 1
♦, I don't think that it would have made a world of difference.
As for not reaching slam, I do think that your partner should have made a cooperative move at some point. Her
♣, while short, were strong, and you have to be looking at holes in that suit, yet you were making moves. Furthermore, you were still trying after she showed wasted hcp in
♠ and, in that context, her relatively weak
♠ (and compensating values elsewhere) should have persuaded her that her hand was actually very useful to you.
