The opening lead was a low Heart, which was Ruffed on my right, with a Club coming back. Won the A of Clubs, LHO playing a discouraging Club, and played Spade to K and a Spade back to A, since if Spades were now 2-2, hand was cold. LHO pitched a Heart, meaning RHO had ruffed with a natural Spade trick and still had 1 more. Pulled the last Spade with the Q, LHO pitched another Heart. Cashed the Q of Hearts, RHO pitched a Club. Now cashed the last 2 Spades, pitching the 2 Clubs from Dummy, both opps pitched Clubs.

In the 5 card ending, dummy retained the K6 of Hearts and the A83 of Diamonds, my hand was the Q of Clubs and the KQT4 of Diamonds. LHO held 2 Hearts and 3 Cards, RHO held 5 Cards. I played the K of Diamonds and the low Diamond to dummy, both sides following, then cashed the K of Hearts, on which RHO pitched a Club and I pitched the Q of Clubs. When the Diamond was played from Dummy, RHO of course played low. Now what?

It is known that LHO has a Heart and 1 card left, and RHO has 1 unknown card left. If the squeeze worked, the J of Diamonds is singleton on the left, if the K of Clubs was offside, LHO retains the Heart, and the K of Clubs, and the J of Diamonds is on the right. The opponents were quite good and had not given any real clues in the play, and had not hesitated during the play at all.

I eventually played for the squeeze to have worked, but LHO had the Club, so I was down 1 for a push on the hand. Not sure of this can be worked out correctly, if it is a pure guess, or if it works out better in the long run to play for the squeeze. Gave the hand as a play problem to a couple of very good players, and they all played as I did, so guess have to congratulate opps on a well defended hand and on to the next. We did have fun on the board, when RHO ruffed the first Heart, I commented that she was not a nice person, she laughed, when she had the long Spades, I said she was almost off the Christmas list at this point, we both laughed. So it was all good, but still frustrating to not get it right.
