In the original deal,

West had: K52 QT Q863 JT76

Only 8 declarers made it out of 47 in 6.

When West has the long s, it looks reasonable to play A, K (pitching a from dummy) and ruff a .

The analysis (as far as I was able to manage):

(1) When West has xxxx:

Now, our s are good. We cash A, come to K, discard a on a good (West following), and ruff a . As long as West has at least two s, we're home.

(2) When West has xxx:

We come to K and play another . If West has 3-3-3-4 distribution with Q, (s)he will have a problem. If West discards a , we ruff a , cash our last trump and play the good ; if (s)he discards a , we simply cash A and J. A rare endgame!

(3) When West has xx:

In this case, finesse was necessary, in addition to finding West with Q to the third. So, we go down because we cashed top s.

(4) When West has Qxxx:

As in (2), we come to K and play another . Now, the last resort is West's having doubleton Q.

(5) When West has Qxx:

We come to K and play a good . West ruffs and plays . Then, we still need to find West with Q.

NOTE: I haven't looked into the case where East has the long s; however, then, success probability is lower.

EDIT: In (2), the phrase “we simply cash A and K” was corrected as “we simply cash A and J”. Thanks for the notice.

I had once had a chance to play against the Schwartz Team (with Krekorian, Casen, Blanchard) at the first match in my only Spingold experience in the 1990s, and got knocked out right away. It was an unforgettable event…

My condolences to his family and friends.

Recollecting the other articles of Liam Milne; I am still not sure about the catch in this one, and waiting for a conclusive statement from him.

Happy new year.

Thanks for the info about “equal level conversion”.

Kit Woolsey:

Assuming that West has six s (as implied), I don't think that (s)he can have 2 s and a void.
In that case, West would have: JTxxxx xx - AKJxx, and East: Axxx x Kxxxxxxx -.

Also, it is not likely that West would have 3 s and a stiff (JTxxxx xxx x KJx), because then East would have: Axxx - Kxxxxxx Ax. ( honors are interchangeable.)

In both cases, I believe, East would not bid 2 initially, and would hardly give up to 5 eventually.

Although I find the line you suggested perfect, it may not mean much under the conditions given here.

6 is cold because partner's hand, which was the subject of an earlier poll below, is AQx x Q9xxxx Axx.

Do you think (s)he should have bid 5 over 4?
If passed, what should (s)he do now over 5?

I didn't expect that either, and checked the results sheet again to see: 12 times 1430, twice 1660, 22 times 680 and 4 times 620. 4 pairs must have played 5.

Thank you all for your valuable and interesting comments.

According to the majority view, North underbid; nevertheless, with respect to the minority view, South might have cue-bid with 4 (over 4) or started with a double rather than 3 overcall…

I am convinced that our bidding was not as normal as I thought, while the saying of Kursat's grandma and Art Korth's initial comment have a somewhat relieving effect.

Now, IMO, the action placing N-S best would be the double of 3 by North, as suggested by Petter Bengtsson (and seconded by David Caprera).

NOTE: slam was bid at 14 tables among 40 (no slam), 26 played in game. Of course, this may not imply much since I guess some Easts passed with (xx QJ9xxx xx QJ9) at first chair vulnerable, and some opened 2; both cases would lead to different bidding scenarios…

Because both 3 and 4 bids were non-forcing, 4 would be interpreted as an alternative (and probably better) spot at a lower level in a preempted auction, rather than a cue-bid. This partnership had no misunderstanding regarding that, but failed in finding the proper level.

This is another point I am not sure about:
i.e., could South start with a double, planning to bid s if North bid s? Wouldn't that be an overbid?

3 was pass/correct (with 3-4 in majors), as you deduced.

7 would go down 6; resulting in -1700.
It would not be difficult to find the ruff.

As Art Korth mentioned above, 4 was an attempt to find the best strain (and it was understood that way in this partnership), but the level turned out to be too low.

Please note that the singleton in North may not be needed to make 6 in .

I suppose, that creates problems with natural overcalls in a Mj (as a flaw). Here, it is very common to use double (over 2 multi) to show general strength; of course, it has its own flaws.

I didn't know about that kind of usage of 2 (over multi 2 with a weak Mj only). Thanks for the info…

Who should do what in your opinion? Should North not bid 4, or something else?
