2♠ was a weak jump-shift.
Partner leads a low club (3rd/5th).
You put on the J, declarer plays the A and leads the ♠J to the K. You exit a spade.
Declarer plays the ♥A and partner throws a highish spot which you know probably means she's giving you count.
Now declarer cashes the ♣K and leads a low club off dummy, your play?
