Strip squeeze

During a MP tournament I picked up the following collection:
♠ K6
♥ AQT42
♦ KQT4
♣ K6

The auction went (uncontested):
1♥ - 1♠
2♣! - 2♦!
3NT
(2♣ Gazzilli ; 2♦ shows 8+HCP any)

I decided to make the practical bid of 3NT, instead of 3♦ which would show my distribution.

LHO lead the ♦3 and dummy comes down with:
♠ AQJ2
♥ K7
♦ 8652
♣ T93

♠ K6
♥ AQT42
♦ KQT4
♣ K6

Suppose RHO takes ♦A and returns a small ♣. What do you do?

Your best chance is to play the King. Whenever the Q or J is in West's hand, you're losing 4+ ♣ tricks if you play low. When you play the King you only lose 4+ ♣ tricks if LHO has ♣A.

At the table however, RHO won ♦A and returned ♦7 for my King (LHO playing the 9). I played a ♥ to the King and a small back only to find out that RHO shows out! ♥s are 5-1. Now what?

We have 10 tricks on top. Suppose we give LHO a ♥, what will he do? He may play a ♣ in which case we make 11 tricks unless they cash the Ace, but he could also play something else.
We can also take the ♥, return to dummy and play a ♣ to our King. But that's dangerous.
Our 10 tricks and the 1 trick opps already have makes a total of 11, that's 2 tricks remaining, which is good for an endplay. We can clear the ♠s and the ♦s, keeping count of the ♥, and eventually endplay LHO with a ♣ so he has to play in our ♥QT. If LHO has ♣A he won't be able to defend against our line of play, and we have an additional chance he has ♣QJ (in which case RHO will win ♣A but will have to play to dummy's T9). This is definitely a better and safer way of getting a second overtrick.

So I played ♥A, 4 rounds of ♠s discarding ♥4 and ♣6, followed by the rest of the ♦s.

On the last ♦ LHO was squeezed:

Dealer: South Vul: None Scoring: MP	♠ - ♥ - ♦ 8 ♣ T93
♠ - ♥ J9 ♦ - ♣ A5		♠ - ♥ - ♦ - ♣ QJ87
	♠ - ♥ QT ♦ T ♣ K

If he discards a small ♣ I'd still lead my ♣K just in case LHO has any honour (if it's the Jack or Queen, I'll still make my 10th trick in dummy). This would only lose if LHO had no ♣ honours. In reality, LHO would be endplayed and would have to play ♥ into my QT.
If he discards a ♥, my ♥s are high.
So his only chance was to discard ♣A, which didn't help.

3NT+2 obviously was a great score.

This was the full hand:

Dealer: South Vul: None Scoring: MP	♠ AQJ2 ♥ K7 ♦ 8652 ♣ T93
♠ T43 ♥ J9853 ♦ J93 ♣ A5		♠ 9875 ♥ 6 ♦ A7 ♣ QJ8742
	♠ K6 ♥ AQT42 ♦ KQT4 ♣ K6

Notice that if RHO would've returned a small ♣ at trick 2, we would've gone down 3!
