Bowring Squeeze

This hand came up in the recently held Karnataka State Championships in Bengalooru's Bowring Club.

I'll present the North -South hands ( no need to rotate the deal; South was actually the declarer ;p) Opponents do not bid at all; so auction & Vul don't matter. [Assume you are playing IMPs, though the deal came up in the MP event ]

K4
AK3

AQ95

Q62

The lead is spade 3 to which RHO plays the Ten.
Plan your play.

If you decide to play a low club to the Queen, it loses to the king ( RHO plays the 4 of clubs) and the opponents cash - hold your breath - three rounds of spades (lucky, spades are 4-4) State your two discards from hand and one discard from table.
Say RHO keeps the lead at trick 5 and returns heart 2, 5, 8 to dummy's King. There is no way clubs will yeild 2 tricks. The ninth trick can come if Diamonds break 3-3 - how will you go about playing the cards?
If you play Club Ace at trick 6, you'll see Rho discarding a Heart.
Figured out the distribution of the whole deal?

Here is the hand RHO held.

QJT2
762
JT62
4

Also, do you see how this comfortable position is broken?

You forgot to mention that the contract is 3NT :P

Also, the defenders distribution cannot be known completely even at trick 6. But it does not matter, you are playing for one of several chances.

I hope you crossed with a diamond at trick 2 to lead a club to the Q. When the defenders cash spades you should pitch only clubs from both hands. Whatever the defenders exit with after that, you cash the top diamonds ending in dummy and cash the club ace at this position:

-
4
-
A98

-
AQ9
9
-

If the diamonds broke 3-3 you already have trick #9.
If either opponent guards all 3 suits he has already been squeezed.
If either opponent guards the clubs as well as the hearts he is caught in a simple automatic squeeze.
If east guards the diamonds and west the clubs you have a normal double squeeze and it does not matter who guards the hearts.

The last case is the one we have on this deal, but basically you are down when east guards clubs and diamonds and west the hearts - you could have then made it on a different squeeze, but this sequence of plays works on the most layouts.
