It isn’t anything. I’ve not discussed this with anyone. If I bid 5H and partner bid 5S, I think 5N could logically be played as a grand slam try...possibly even old-fashioned Grand Slam Force. Say I held AJxxx void AJxx AQxx
I think it important to keep these sequences as simple as possible. No matter how one thinks partner ‘should’ take an imaginative call, the reality is that, for the great majority of partnerships, partner will often think of something else that, to him, makes just as much sense.
For me, since I am not looking for spades, 5N is obvious. Both my regular partners would, I am certain, know this was pick a slam, with emphasis on minors.
Equally, I think 5H clearly involves spades.
However, once opener bids spades, 5N is the sort of action I’d strive to avoid.
