I would open 4 as S and that would probably end the bidding...
I do not have enough defence for a 1 opening, my suit-quality is acceptable and 3 is a serious underbid.
Some N might press on, but my partner wouldn't :)
If we had reached 6 I'd ruff the J
Now I can either try to drive out the A and set up the Spades, which will always work if Spades are 3-3. If Spades are 4-2 I need to guess to play the finesse/ruffing finesse right.
Alternatively, I can cross my fingers to guess the right finesse and ruff the remaining 3 clubs in dummy.

I don't know which line is better, my guess would be it is setting up the Spades

Regards
Janis

If West has A they will lead a and kill your entry to cash spades. Even if west wins A killing the entry might work (not sure)

The two auctions I know were 4-6 and ours which was:



Since we had exclusion available and I didn't use it or blackwood, 5 guarantees a club void as 5 might be murky.

most declarers ruffed the club, played AQ covered with the K and ruffed, opinions diverged at this point.

Hands like this are difficult for DD auctions because there are always plenty of subjective decisions that can be influenced by seeing both hands. I might well reach the slam through an auction such as:

1 = ~10-17, 5+ hearts, unbal
... - 1 = INV+ relay
1NT = min, <4 spades (a Walrus underbid really but planning to show distributional extras if partner shows an INV hand)
... - 2 = GF relay
2 = 4+ clubs
... - 2 = relay
3 = 7+ hearts, 4 clubs, 0-2 controls
... - 4 = relay
5 = KQ, KQ, denies K/Q
... - 6 (North could still find out about a singleton K below 5 but if bidding slam anyway it does not matter)

...but equally North might easily decide it is too risky and stop in 4 or 5. Stopping is probably the correct DD action I would guess.

For the play, my first instinct was the start CY suggests but I am wondering if starting with the diamonds is not better:
ruff, A, Q ruffed.

If East covers this, we are all but home:
ruff, J throwing , ruff, ruff, A, ruff, J.

If East does not cover then we need to find East with Kxx or Kx + A or Kx + :
A, Q, covered and ruffed), ruff, J throwing , ruff, ruff, ruff, J

This is obviously not the best line DD but it probably offers as good chances against a real-world East as the technically better lines.

It's hard to avoid 6 (suggested auction on left),
Although it's a poor contract on J lead.
Clutching at straws. I like the main variant of Zelandakh's line:
Ruff the lead. Cash A, Cash A. Lead Q covered and ruffed.
Ruff a 2nd . Cash J, chucking a 3rd . Ruff the last with 8.
Ruff your last . Ruff a . Draw trumps.

I was dummy, partner had to play this one, the hand has some interest in the play:



I don't think you can actually do it on this lead because W has 10, only 2 spades and 3 diamonds and you're an entry short and end up promoting 10.

The curious thing was that it can be beaten played by either hand. Imagine the fantasy auction starting with a NAMYATS type 4 resulting in N declaring. If partner leads a diamond, can you withhold the K as W ?

There are also some amusing end positions involved as on a diamond to the KA you can potentially rumble the trumps leaving:



Where E is squeezed in 3 suits the trick before dummy.

The Ostrich, who hasn't yet attended the lesson on finesses, makes easily,
Ruff the opening lead.
Cash A and A,
Ruff a .
Ruff a .
Ruff a .
Ruff a .
Ruff a .
Lead K.
Win the return.
And claim.

OK, because A drops and he only has one trump, means the diamond lead is required to beat it

Although I think it's a bad line single dummy.

I was about to claim just that for my auction, and when W leads the J I'll insist that E lead one :D
