Slams we missed

Apart from the 2 grands we've missed (we bid only small slam) we only missed 2 slams. Coincidence or not, both contained a void. Note again that these were also 26-point-slams, just like the ones we bid...

pass - 1NT! - pass - 2!
pass - 2! - Dbl - 4!
pass - 4? - pass - pass
pass

1NT = 12-14, balanced or semibalanced (4441/5422)
2 = puppet to 2, many hands
2 = obligated
4 = shows a splinter, good and no stopper.

The question whether South should've bid 4 remains unanswered. South claimed that a splinter bid is an "evaluation bid" (and with Kxxx he should refuse), while North claimed that South should just show his cue, because showing a good suit without Ace and Queen is very suspicious to say the least. North also claimed he's endplayed if no cue is shown by the opener.
Both players agreed that North must have very long from KJ with slam interest. Since he doesn't hold anything in or , he must have solid s as well. But that doesn't guarantee that we won't lose 2 or 3 tricks. 5-level is probably safe, so percentage wise South might've just cuebid his A, but still it's a borderline decision.

1! - pass - 2NT! - 4
4 - 5 - 5 - pass
pass - pass

1 = 14+HCP, natural, F1
2NT = fit, either invitational, or GF with a void

Afterwards South admitted he should've just bid 6 instead of 5. Opener shows a non-minimum hand by his 4 bid.

Hi!

On the first one I think 4D is a no-brainer. I've heard the splinter as an "evaluation tool" argument but does not agree in a situation like this. With a useful doubleton and AQxx and ace of D, I'd be prepared to move past 4H as well.

Second one, I think part of the problem is responding 2NT instead of showing the void with Hxxx and an outside trick source. In the actual auction, I agree that 6H is called for.

After hearing 5H, North might have bid 6H also.
