5NT should fairly specifically ask for the SQ here should it not? We have 6m available as SSAs and partner already denied an outside king. That said, there is something wrong with this auction. 3S appears to demand cue bids but partner could not find a spade cue bid of 3NT with the ace and king. Anyway, partner has AK/AKQxxx/xx/xx plus one further card. If it is a club then the grand is poor, otherwise it is decent enough. At teams I think it is worth it.
Since Opener has denied a minor Control, I too think 5NT would also be a
♠Q-ask, whereas 6C or 6D would be specific 3rd-round Ctrl-asks .
For example bidding 6C, the replies are:
6H = no 3rd Rnd Ctrl in Cl
7H = x x in Cl
6NT =
♣ Q
7C =
♣ Q J
You would like to hear the 7H reply ( as you noted x x in Cl and the grand is on )
And, eventho the 6NT reply won't help as far as the grand is concerned, it won't hurt you either.... you still have 12 tricks in 6NT .
However, with the 7C reply you would have to rely on the
♣-finesse for 13 or a fortuitous 3-3
♦ split.
EDIT: but from the 14-16 constraint of the 3H-jump rebid,
Opener can't have the Cl Q .... so you are essentially
safely asking for x x in Cl....
But you may still have to rely on the Sp hook if :
A K x, A K Q x x x, x x, x x .
