It is possible that RHO has psyched the 2NT call but in that case RHO probably has length in both majors. Therefore it seems unlikely that partner has a 10-count including QJx of hearts.
Of course I didn't say that the chance that we have slam is miniscule. If partner has 4 or more clubs then we likely will make slam and 3 may be plenty. However, I don't think it is very likely, as MFA said, and if RHO doubles 5C then that makes it less likely. In that scenario I am content to play 5CX.
We have no reason to think 2NT might be psychic. We just have a 13 count, so everything looks normal. East is a favourite to have a somewhat balanced hand with at least two cards in each major.
One of the ideas behind 5
♣ is to guard against that we don't have slam. I don't trust east to be able to judge the situation at all over 5
♣ undoubled. Basically I play east to double 5
♣ just about always. We could easily still have 12 or 13 tricks in clubs, even after a double. So if east figures out to run from 5
♣XX, I think we will have an excellent chance in slam, because if he is very strong in clubs he definitely wont run. So in a sense I hope to play 5
♣XX when there are 11 tricks and slam when there are 12 tricks.
But there are many things that could go wrong. I admit.
So, hell, I don't know. That's why I posted.
