Well, 4S is a picture bid (see the OP). 2N-then-4S for me would show a 18-19 balanced with three very good spades - you can't undo denying four-card support.
If this is not a GF, just turn the K of spades into the A.
Ok, I am sorry for you that you tied up your hands and legs with almost never coming this picture bid and/or spared a very important auction to a 3 card fit and 18-19 hcp, and have to bid with 3
♠ with all 4 card bids and strength or shape or controls when 3
♠ is pretty space consuming.
Don't get me wrong, I am not a big fan of fast arrival and I understand that "picture bids" regardless of auction, means "rare hands" that needs showing rather than asking. And I like them. But imho 2 NT is under employed by many pairs by rejecting fit. Imo again, if we are going to start 2
♣ with your example and Andy's, instead of 1
♠, we should have better options than just having to bid 3
♠ over 2
♠. And with all due respect to "picture bids" and or whatever range 3 card fit bids, they should not be priority.
EDIT: I agree with P.K that pd will never reject a serious slam try with 3 keycards btw. I would not reject even a non serious slam try with 3 of them.
