  Play the 2.

You know partner also has the K, and normally you would give an encouraging signal when you hold the Queen.
But with this hand you want partner to switch to ♣s as soon as possible.
So you play a low .

West looks at your signal, then looks at dummy, then looks at your signal.
He knows you want a switch and it looks like a switch to ♣s might work the best.
South plays a low ♣ from dummy, you win the ♣J.
Next you play a low , taken by West with his K.
West leads a ♣. Dummy plays the ♣K, you win that, cash another ♣, then cash your Q.
That first signal led to your side winning the first 6 tricks. Wow.
