Close one

Here's one from a club evening friday evening:

Dealer: North Vul: EW Scoring: MP	♠ x ♥ KJxxx ♦ QJxx ♣ Axx
♠ QT9x ♥ xxx ♦ KTxx ♣ xx		♠ A8xx ♥ Ax ♦ x ♣ KQTxxx
	♠ KJxx ♥ Qxx ♦ Axxx ♣ Jx

Playing f2f with my MOSCITO partner, he opens the bidding with 1♦ (showing 9-15HCP, 4+♥, can have a longer minor) and RHO intervenes 2♣. I have an easy takeout double, LHO passes and partner bids 2♦ showing 5♥-4♦ or 4♥-5♦. I bid 2♥ showing an invitational hand with 3♥ support (with weaker I would've just supported immediately, even with 4♠ - it's the system). LHO and partner pass, and RHO balances with 2♠. Now what? Well, I decided to just double, since I wasn't sure about a good fit. Partner decided to pass it in. I disagree with this decision, because we have a double fit and it seems logical that opps will also have a double fit. Playing 2 anything will probably be easy, and they also know where to find the ♠s. Even though we're NV vs V and may have an easy +200 it's too risky imo.

Anyway, the full auction:
1♦! - 2♣ - Dbl - pass
2♦ - pass - 2♥ - pass
pass - 2♠ - Dbl - pass
pass - pass

I start with ♦A and don't like what I see in dummy! My ♠J will be caught in a finesse and I just made ♦K high (and chance is that RHO doesn't even has one!). RHO seems still to have one, so I switch to ♥. RHO takes his Ace and plays a small ♠. It's imo quite clear that he wants to try to discard a ♥ on his ♦K so I take ♠K and play ♥Q and another ♥. RHO ruffs and plays ♣K which partner takes. He returns a ♣ which RHO takes with the Q catching my J and he plays for some reason small ♠ to his Queen!!! Because we cut off declarer's communication, I think he thought he could only make it if ♠s would split 3-2, which is virtually impossible. The winning line of play is to just run ♣ and make me ruff... Now he's completely screwed. He cashes ♦K and ruffs a ♦ with trump Ace and plays ♣T. This is what's left in dummy:
♠ T9
♦ T
And I still have:
♠ Jx
♦ x
Partner still holding ♦QJ we still have to make 2 tricks. If I discard my ♦ I'll only make 1 more trump trick, if I ruff with the Jack dummy discards his losing ♦, so the only way to make 2 tricks is to ruff low!

+200 was a nice top, and both me and my partner had a bit of excitement because the downtrick seemed very far away. All decisions turned out to be great: the ♥ switch was necessary to make declarer ruff, I had to take ♠K immediatly because the ♥ loser would've gone away, it was very good from partner to take ♣A immediately and continue ♣ destroying all communications, and I found a way in the end to make 2 tricks by letting declarer overruff.
