Given that things are rather quiet, how about this one.
Both sides playing 2/1 with strong NT.

After West makes the contract, South calls you to complain about the very slow double (acknowledged by EW).
How do you evaluate the situation and how do you proceed?
Would you look at the full hand diagram with double-dummy analysis if you had it available, and would it effect your evaluation if South had done so before calling you?

You find peers of West to poll. First ask them what they would consider and do after the double without telling them that it was slow; this provides you with the logical alternatives. Then tell them that the double was slow, and ask which of these actions they think are more likely to be successful given what it suggests about doubler's hand; these actions violate Law 16.

You only look at the hand diagram to decide if NS were damaged. If they can't make 2♠ they were getting -200 or worse, so -140 is a gain and result stands. But if they could have made the contract, you need to determine if pulling the double was suggested by the break in tempo.

"Could" make 2♠, or "would" make 2♠? This is tough to determine in itself, and definitely not based on double dummy.
