V vs. N, partner opens 1st seat, you hold void, JT854, AKJ72, QT2

1♥ (P) 2N* (3♠)
4♣ (P) 4♦ (P)
5♥ ?

Good general rule, when they have bid one suit and we have not cuebid it, a jump for 5 demands a slam bid if partner has their suit controlled.

Ok, that's good - this was the hand

That's nice. I've never before seen it explicitly said like that. I assume this could have gone bad if Jillybean had a stiff spade.

How do you continue after the 5M jump when you hold a 1st round control of the suit? Show your number of aces? bid 5♠ (their suit) ? cuebid in another suit? Do you have a way to show that you have a void and not an Ace?

Yes, I would cuebid if I had first round control. You can cuebid 6m also implying first round control. I would bid 5N with the protected SK. No, I do not play any way to show a void rather than the ace, in this auction there is probably room to do it though if you want.

Does anyone play that 2NT denies a singleton or void?

Just to clarify, 5M demands a slam bid if partner has 1st or 2nd round control?

And in this auction, since I had first round control I could have bid 6♦/5♥?

Yes.

Yes, either 6D or 5S.

2NT would not have been my choice.

Why not?

Yes, just raising to 6♥ normally shows a 2nd round control (probably a singleton).
With a 1st round control you can cuebid 6♦ , or maybe 5♠, to suggest that even a grand slam may be makeable.

I assume he would splinter. If you have no way to show short spades after 2N, han is probably right.

Correct. Imainge if your partner had the CA instead of the CK, the bidding would be the same but 7 would be good.

I play denies a void, would have started 1♥-3♠.

In the past I would have always splintered but I have found with a slammish hand a splinter often takes up too
much room and I do better going slower and using J2N. I would happily splinter on a weaker hand.
