It is tempting to just bid 3NT and hope the s come in.
But not when you have a 4-card Major suit. Instead you bid a Stayman 2♣.
Partner says 2♠; what do you bid next?

Partner says 2♠; what do you bid next?

Well, he has 4 ♠s. That's why you used Stayman so you bid 4♠.

  Loser List: ♠ = 2/3/4 : = 0 : = 0 : ♣ = 0 :: Total = 2/3/4

Missing 5 ♠s, the most likely split is 3-2, (68% of the time).
You win the ♣A and play a small ♠ toward dummy. West puts on the ♠Q which you take with dummy's ♠A, East following with the ♠6.

Do you play ♠s again? or not?

  Loser List: ♠ = 2/3/4 : = 0 : = 0 : ♣ = 0 :: Total = 2/3/4

Missing 5 ♠s, the most likely split is 3-2, (68% of the time).
You win the ♣A and play a small ♠ toward dummy. West puts on the ♠Q which you take with dummy's ♠A, East following with the ♠6.

Do you play ♠s again? or not?


Not. With both defenders following suit, the possibility of 4 ♠ losers is gone so you can lose at most 3. But that ♠Q from West is ominous.
If you play another ♠ and they do split 3-2 you will make 11 tricks, losing only 2 trumps.
But if East has 3 ♠s left he will win the trick, pull all the rest of the trumps, and lead a ♣ to West.

The guaranteed way to make the contract is to play no more ♠s, but to start playing winners. The defenders can make their 3 trump tricks but you maintain control of the hand.

  As you see, playing a second trump would have been disastrous.

But with a different distribution, (3-2), playing the second trump would have been great.

Considering probabilities it looks like this.
If you play the second trump you will make 2 overtricks about 70% of the time, but you will go down 4 about 30% of the time.

If you stop with the ♠s and start running s you will make your contract 100% of the time but will never make an overtrick.
