It is usually correct to pass in this situation, particularly if you are not strong in partner's suit.
So you pass and partner doubles.

Partner's double is called a Cooperative Double. It doesn't mean he has a ♠ stack, it just means that your side has the balance of power and East may have over-reached himself.

If you had good s you might bid them now. Or, it is possible that you could make 3NT. But it is likely that you are going to make a bigger score in penalties so you pass.


 Summary 
  ♠ A J 4

A K 9 7
♣ A 8 6 5
