Answering Blackwood would seem to be one of the simpler tasks one faces. Veteran players will be familiar with some issues, two of which are raised in this question posed by a correspondent.
You hold: Q 6, K J T 8 7 5, K , A J 9 4
At IMP’s (vul not provided) you open 1 and your LHO bids 3. Partner cries 4NT and the opponents are now quiet.
First question: Do you show the heart queen with your response?
Let us suppose that you just bid 5. Partner now tries for the grand with 5NT. Do you accept?
Let us suppose that you merely show your diamond King with 6. Partner now signs off in 6.
My correspondent wants to know if you have anything left. I have a rather strong opinion, but I want to hear from others first. What do you think?
