I also ended up doubling, largely because I'm not sure how good partner's clubs are.
We got 5
X-3, but can definitely make a club or heart slam. Partner has:
8
A J 4 2
4
A K Q 9 6 4 3
Does it make sense for him to pull the double, or do pre-empts just work in this case? Also, is there a reasonable way to find the heart fit?
