I drew two rounds of trump. They were 2-2. Ruffed ♥ crossing back in ♦ and pulled the last ♦. Both opps had three ♥'s but RHO dropped ♣3 on the third diamond. I played a third round of trumps ending in dummy. RHO dropped a ♥ and LHO a ♦ reaching this:
Scoring: MP
I lead ♣4 from dummy and got ♣J from RHO

South opens a 15-17 NT and you reach 6♠ after stayman and blackwood.
Lead a smallish ♦
Spades are 2-2
