One for the defense

Here's a nice hand from a few days ago:

Dealer: North Vul: NS Scoring: MP	♠ 6 ♥ T4 ♦ AT964 ♣ AT982
♠ K875 ♥ QJ86 ♦ J72 ♣ Q4		♠ AJ4 ♥ A753 ♦ KQ3 ♣ KJ3
	♠ QT932 ♥ K92 ♦ 85 ♣ 765

The bidding went:
1♠* - Dbl - pass - 2♥
pass - 2NT - pass - 3NT
all pass
(1♠ shows around 9-14HCP with 4+♦, and can contain longer ♣)
My RHO probably bid 2NT just to try to rightside the contract.

I was sitting South and had to lead. I generaly don't like agressive leads, and there was every sign not to on this particular hand.
- Partner will probably be short in ♠ and chances are big that I won't have an entry if I can setup my suit anyway.
- Leading ♥ from under Kxxx gives the entire show away.
- Declarer will probably have a double ♦ stop.

So I decided to lead a ♣, hoping to reach my partner's longest suit. We lead 1/3/5 and I thought my count would be important: I lead the ♣5. Partner nicely held up his Ace and declarer won with the J. Now ♦K was played and partner took it immediatly, gave the ♣ suit a second of thought and correctly played a low ♣ to keep communication. This only fails when I had ♣53, but you might still get your trick back later. So the communication was still open. Declarer won in dummy and finessed ♠ to my Q. I had an easy continuation, and partner did what we worked for: cash the ♣ tricks. Declarer discarded ♥ in his hand and in dummy, so partner returned a small ♥ to his Ace. Now declarer tried a ♠-♥ squeeze (or ♠ splitting 3-3) by cashing his ♦s. On the last ♦ I hold ♠T92 ♥K, and dummy still had ♠K87. I had to keep my ♠s since partner was all out (I already knew declarer had ♠A as well), so I discarded my ♥K. Lucky my partner had the ♥T, otherwise declarer's squeeze would've worked. -2 was a great result.

GIB's Double Dummy Solver says we can only make 5 tricks. Declarer messed up by keeping his ♦ communication. If he kept ♠K87 ♥QJ ♦J in dummy, he can easily take ♥A, play ♦ to the J, a ♠ back to his Ace, and the last ♦. NOW I'm squeezed in ♠ and ♥...
