3S was some kind of stopper asking bid.

Do you have a decision to make a trick one?


Looks like declarer has a singleton spade for the 4NT bid.

Declarer likely has 6+ hearts the DK and CA. If declarer has two or fewer diamonds, then declarer is cold.

So give declarer exactly 3 diamonds: a hand like ?, KQJxxx, K9x, Axx

Now if declarer has the singleton SJ, then you get squeezed in diamonds and spades, thanks to the diamond and spade nines!

So give partner the SJ.

Now if you play low, partner could potentially continue the SJ and now you are in charge of protecting spades and get squeezed again!

So you overtake with the A and declarer follows low. Now you play the SQ having partner keep the SJ.

Now when declarer draws trump throw your ST at the first opportunity! This will force partner to hold on to the SJ and the squeeze will not operate.
