I started thinking about the possibility that W might have KQxxx. I think it doesn't matter.

T1, Heart A
T2-6, play diamonds, tossing a spade from the board.
T7-8 club K and A. If E held 4+ clubs run the ten and claim 12 tricks If clubs are 3-2 claim 12 tricks. If West hold 4 then:
T9-10 play spades, ending in hand. You now hold Q8 in clubs with T9 (and a spade) on the board., and you hold the J of hearts.
W has f three cards left. If he has pitched so that he has only one club, cash your clubs. If he still has two clubs then he has only one heart. If he has pitched the ♥ Q (he might, in fact should since he needs to get off the endplay and partner rather than declarer might have the J) cash your Jack. If he has kept two clubs and the heart Q, throw him in.. Given that he started with the heart Q (highly likely but not certain given the auction) and given that E has shown out on the second club, you know exactly what he has come down to.

The sole requirement here is that W hold the ♥ Q. The bidding doesn't matter, the original distribution doesn't matter.

I think Ben's excellent threads deserve more replies, so I'll give it a shot.

I think there is a 100% line.

I have 11 cashing tricks so I need one more. A fourth club is the obvious candidate. This is trivial if the suit breaks 3-2, so I will think about bad breaks. West's opening bid suggests that east is more likely to have long clubs, so I will cater to this. But first I will run the diamonds, pitching a spade from dummy, and watch the discards; maybe something good will happen. Next I play ♣KA. If west shows out, I hook east for the 12th trick. If west still has ♣Jx, I cash ♠AK. If west unguards a round suit, I cash out. If not, he is left with ♣Jx ♥Q - now I throw him in with the heart, forcing him to lead a club into my Q8. Making 6.

I guess I would call this a potential finesse, followed by a strip squeeze and endplay. So I marked all three in the poll. Not sure this is really B/N material, but maybe I missed something simpler.
