Righty had bid hearts, so the opening lead was a small heart.
Note the effect of winning in hand, unblocking the clubs, and running the diamonds. This position is reached.

The last diamond winner squeezes Righty. Giving up a club directly yields a trick, as does giving up a heart. Yielding a spade allows declarer to cash the queen of clubs, pitching a heart loser from dummy, then to lead a spade to set up a spade trick.
Structure
I have not seen this type of squeeze mentioned before. Maybe I just missed it. It certainly seems to have enough structure to deserve mention.
Obviously, you need the first-round control in both threat suits, like a normal triple squeeze. And some communication.
What is happening is the the defense has the two top tricks in a suit, and one is being squeezed out to make only one threat. I call this a promotion threat. Discarding the ace doesn't create a winner, but allows the queen to be promoted to a winner.
