North plays 6NT on the ♠2 lead. He wins in his hand and leads a spade to the king, then runs the ♥T to the jack and queen, unblocks the ♦AK, east discarding a heart, and leads a low club to the ten and queen. A club is returned to the ace.
The position is now this:

---

At this point, east should start paying attention. North now leads the ♠9 to the king, which promotes the ♠8, and west discards a diamond. Next comes the ♦Q discarding a club. If east discards the ♥8, a diamond is cashed and a heart can be run through west. If a spade is discarded, declarer cashes out 4 tricks very carefully, one in each suit. If east unguarded a club, the ♦J could be cashed, discarding a heart, and North's hand would become good.

N/S are in 7NT, the lead is irrelevant. Declarer cashes all of North's winners and East with his 6 high hand is squeezed in the majors. East's hand has a pip count of 50 compared to 53 in the OP

Can't you adjust to (leaving the majors the same):

N: ♦AKQ5, ♣AKQ76
E: ♦6432, ♣2
W: ♦J107, ♣J1098
S: ♦98, ♣543

Where he gets squeezed in 3 suits on the second club with a pip count of 47

That works, but I've just found a layout that goes 1 better still

OK, maybe this isn't as pure since it can also be made by squeezing West, but if you cash the minor suit winners here, East gets squeezed with a pip count of 46.

[Cyberyeti]

Actually, adjust your original to (same majors):

N as is
E ♦5432, ♣2
S ♦986, ♣43
W as is

and don't you get a legitimate 46.

[manudude03]

yeah, you can also get a legitimate 46 if you take the 2nd layout and rearrange the minor suit winners so North has 5 solid clubs and Axxxx in diamonds, West can then throw a diamond and still maintain guard there (there is no club threat)

[manudude03]

I think going lower is going to go into layouts where there is a play that doesnt involve the weak hand getting squeezed. Here's a pretty sketchy 43. I'm pretty sure that's the lowest it can go, any weaker and East can't have a 2nd menace.

West leads a diamond against 7NT.
Yes, declarer can make it by triple squeezing West, but suppose declarer makes the mistake of throwing a heart on all the club winners.

After trick 7, the position is this

---

On the penultimate club, West must throw a spade or a heart.
1. West throws a spade, North a diamond and East a heart. Now on the last club:
a. West throws a spade, North another diamond and East is squeezed in the majors
b. West throws a heart, North throws a heart and East must throw a spade, now AK of hearts squeezes West.

2. West throws a heart, North a diamond and East a heart. Now on the last club:
a. West throws a heart, North throws a diamond and with the 9 of hearts high, declarer has 3 heart winners.
b. West throws a spade, see 1b.

Follow 1a for the normal squeeze line
edit: just noticed I can rearrange this into a 43.
re-edit: hands edited
edit-3: missed the defense of West throwing hearts on the penultimate club.
