We played this hand in the Hungarian MP championship. It was very interesting, how could we make a top because of a bidding mistake, playint 3NT instead 4♥ and also there is a very nice double dummy problem of how can we make 11 tricks in a ♥ contract.
We play Smolen, so partner's correct bid would have been 3♠ instead of 3NT, so we could play 4♥ with a comfortable finesse in diamonds. It would have been nice to get other lead, than clubs, because than we could make the same 11 tricks as in a heart contract, if both heart distribution and finesse in diamonds would have been good.
But the opening lead was the Queen of clubs, and East gave the Jack to this trick! What does it mean?
East and West are leading top of sequence, encouraging high, and the lead the honor above the lack, when they ask deblock.
So West surely has KQ10 of clubs, eventually with a long suit.
We have to duck this trick, hoping that West changes suit and we can play the diamond finesse, but West played the King of clubs next. I discarded the two of diamond from dummy, East gave the six, and I got a small chance, that I can score exteremly big, if East doesn't have more club, because than I make the same tricks in NT contract as everyone else in hearts.
So I won the 2nd club with the Ace, and played the Ace and Queen of hearts from my hand, West discarded small club to the Queen of hearts.
Now, it is a great news again. If we are lucky, East don't have any more clubs, so if we cash all spade tricks and King of hearts, than we can give trick 10 to East, who doesn't have other cards, but diamonds. It would be important, that he should also have the King, because than we make MORE tricks in NT, than everyone else in hearts.
So I cashed the spade tricks and the King of hearts, I exited with heart and East had to play diamond from the King, giving 100% score for us.
The complete distribution, which is the start of the double dummy problem making 11 tricks in a 4♥ contract after King of clubs lead, was this:
I wish you pleasant time to solve the double dummy problem!
