Dealer W who opens 2♦ explained as acol 8 playing tricks
N doubles
E bids 4♦ (weak aceless raise)
S bids 4♥
W passes
N bids 6♥

W leads ♠6

You know the W player, and know that he plays a multi in every partnership other than this one.

Take it from here.

Sorry, what does this mean? Is it a diamond oriented hand with 8 tricks? Is it any hand (perhaps some suit or NT) with 8 tricks?

Oh, and there's no way this has anything to do with your other post about obligations...right? ;)

This has everything to do with that, but is still an interesting play problem if you don't actually look at the hand posted there. But you can assume that W has forgotten that he doesn't play a multi in this partnership and has a weak 2 in spades, but to make sense of E's 4♦, you have to realise that he's responding to an acol 2, ie a decent hand of opening strength plus that expects to make 8 tricks opposite a yarborough with ♦ xx.

I finesse at trick one, because that allows me to take a safety play in trumps.

♠J, ♥K, ♥ to the 8 unless East plays an honour. If hearts are 3-2, I have twelve tricks including one club ruff. If East has ♥QJxx and doesn't split, I cash a third heart, then cash my winners and eventually ruff a club.

If East splits from ♥QJxx, I win, then play ♦AK, ♣A, ♦Q throwing a club, club ruff, reaching this position:


East has ♥Q6 left.
I lead dummy's top spades, planning to throw two clubs. Assuming that East was 1444, 1453 or 1435, it doesn't matter what he does - if he ruffs the first spade low I overruff, ruff a club (to which he will follow), and lead the other top spade; if he discards on the first spade and ruffs the second spade low, I overruff and ruff my last club; if he never ruffs I have a crossruff.

This line fails if the shapes are 6115-1462. I'll know about this after the second round of diamonds, but I haven't yet decided what I'd do about it.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn
