Btw, I don’t understand your proposed 3D. Surely that’s a splinter as well, and thus doubly misleading?
Maybe you meant a fake reverse into 2D. I’ve bid more than a few fake reverses, but never enroute to hiding primary trump support. No good player, sitting opposite, will ever imagine AKxx, let alone AKJx, in spades after the fake reverse.
The hand is far too strong for 4S. 4N is a complete guess that could easily lead to going down in 5S and otherwise means tossing a coin after any useful response.
The splinter is not ideal but it’s by far and away the call most likely to clue partner into the basic nature of our hand.
Consider how much we are telling him.
If, as most do, you have to bid 4H here (you may have seen that I can bid 3H as invitational plus)…
Now partner knows you have a gf raise opposite a passed hand 1S response. He also knows your probable shape within one card: you are either 4=1=3=5 or 4=1=2=6. I suppose you might be 4=0=4=5 or 4=0=3=6 but voids are far less common than singletons…again, note that I promise precisely one heart card…I think it very important, for slam bidding, to distinguish a void from a stiff if possible.
With Qxxxxx AJxx Qx x, it’s clear to move towards slam. Since partner could have AKJx x xx AKQxxx (unless you have the gadget with no name where 4C shows about this hand…which I do, lol), we would be violating an important metarule if we keycarded. But I can’t construct a hand on which 5S isn’t pretty safe so I might do it anyway. My main concern wouldn’t be being off the diamond AK but missing slam when he shows 3 keycards…what if he had AKxx x Kxx AKxxx? How can I tell that from AKxx x Jx AKQxxx? I can’t
So over 4H, I think we bid 5C, breaking another metarule by making our first cue in partner’s main suit. We need to hear 5D over which we bid 5H and leave the decision to partner…the fact that he will think we have something like Qxxxx Axx xxx Kx doesn’t worry me too much.
Note how much easier (although far from easy) it is if one can bid 3H over 1S. I guess you can tell that I play primarily imps, since with both regular partners we’ve spent a lot of time, in system design, in optimizing slam bidding😀
I agree in principle and that is why we expanded the meaning of the 4-level minor rebid to encompass this type hand.
PS: was thinking spades and confused 3D as a jump shift. Duh!
