Miracles happen

I played at the club last night with Mary. This deal (rotated) was interesting:

                 ♠ A J 5
                 ♥ Q 10 6 4
                 ♦ A 9 6 2
                 ♣ Q 6

                 ♠ 7 3
                 ♥ A J 9 7
                 ♦ Q J 5 3
                 ♣ A K 4

   West   North   East   South
                  Pass   1NT
   Dbl    2♣      Dbl    2♥
   Pass   4♥      All Pass

The double of 1NT was Alerted and explained as a one-suited hand. The 2♣ bid was Stayman. East-West were vulnerable.

West led the ♣10 won in dummy with the queen. I advanced the ♥10 which lost to the king and West led another club which East ruffed, ouch. East exited with a low heart which I took in hand as West showed out. Ouch again -- I lost to a singleton king. I drew the last trump -- now what? I had lost two tricks and had a sure spade loser.

How should I play diamonds? One way is to lead the ♦Q playing West for the ♦K 10 doubleton. Where were the spades? It seemed they were likely 4-4, so that leaves West with a singleton diamond, so leading the ♦Q won't work. I led a low diamond and West played the ♦K! He had two red singleton kings! A miracle!

The deal was over at that point. I led a diamond back to my queen, cashed the ♣A discarding a spade and played ♠A and another, claiming. If West won, he would have to give me a ruff-sluff, and if East won, he had a choice between a ruff-sluff or leading a diamond which I could run around to the ♦9. Making 4♥ was a tie for top. I wonder how the other declarer played it.

Here's a look at all four hands:

                 ♠ A J 5
                 ♥ Q 10 6 4
                 ♦ A 9 6 2
                 ♣ Q 6
♠ Q 10 9 2 4                 ♠ K 8 6 4
♥ K                          ♥ 8 5 3 2
♦ K                          ♦ 10 8 7 4
♣ 10 9 8 7 5 3 2             ♣ J
                 ♠ 7 3
                 ♥ A J 9 7
                 ♦ Q J 5 3
                 ♣ A K 4
