Some might quibble with North's evaluation. In spite of only 18 points he has 2 "10's" and a pretty good ♠ suit, a case can be made for opening 2NT, but, as I said, I pretty much agree with the given auction.

I think 4♣ by N would have been okay after 3NT in case S had a hand that got better with a club fit, (Qx, Qxx, Axx, KQxxx or xx, Axx, QJx, KQxxx or something unless you'd bid 3♣ with those), but I'd expect S to just bid 4NT with both reds held well and a min with only 4 clubs after that.
The auction is very good and very practical though. I'm guessing you made 6 since you'd need pretty much every heart with W and every spade with E to not make 10 tricks here. And you'd have to misguess diamonds. And clubs would have to not come in

Looks like you need quite a bit of help (either from the defense or the lay of the cards). I don't want to be there at any form of scoring, unless I'm way behind in the last Q of a team match.
edit: e.g., PTP on a club lead, and suppose clubs break 4-2.

What do you think the odds of making 6NT on this hand are, jillybean?
Yep you're right, sorry.

if you find the ♠q (a roughly 50% proposition) you're up to 11 tricks after you knock out the ♥A. you still need something good to happen in one of the suits, probably another factor of 1/2 or so. I'm not arguing this is an accurate computation, but I'd guess this was an approximately 30% slam. "Terrible" is an overbid, but it isn't one you want to get to with any frequency if you want to have consistently good results.
--- edit
it might be a touch higher than I've given it credit for originally; 33 break in ♣ is 38% or so, and the two-way guess in ♦ is half of the remaining 62%, so just combining these two chances gives you ~35% overall. there's also a chance of bringing down the ♥J or some sort of a squeeze.
It's still well below 50%, I think.

The way you should look at this is that if the ♠Q is off, you are sunk. If it is on, you still have some work to do or guess well.

Thr spade finesse is 50%. I think if you add in the "no worse than 4-2" requirement, that probably reduces the chances to about 42%. That brings you to 11. I am not going to try to compute the probabity of getting at least one of the other requirements, but let us guess that the probability is somewhere around 90%. That reduces the chance of slam to about 38%.
At IMPs, this would definitely be wrong, and at MP I suspect it would depend upon what kind of score you need. It was said that only 2 pars were there, so it is a top or bottom thing if you bid it, and the odds are that it will be a bottom. I'd want to be with the field most of the time with this one.
