If East shows up with five s, adding two s to that, 6 vacant places remain in E, but 11 in W. It is now much more likely that West has K; so, cashing a third (Line 3) may be a good idea.

If West has five s (7 vacant places in W and 10 in E), there are two choices:
(1) West has K.
(2) East has K and QJ.

If (1) is more likely, do not cash third , go for squeeze.
If (2) is more likely, cash third , go for squeeze on East.

If both opponents follow two rounds of s, now what?
To get a quantitative result, similar probabilities need to be estimated when E or W has four s (taking into account the numbers of vacant places in each case).

Yes, the slight difference between Line 1 and 2 is that Line2 offers a change of plan if East shows up with 5 s. And, in this case, one may consider cashing the third and go for double squeeze in , to reach the ending in Line 3.

There are three main endings, corresponding to each LINE to be voted for, before we cash the last in dummy. (The 2nd is your choice.)

(1) Dummy: Q x - xxx
Hand: - - T AKQx

(2) Dummy: Q x - x
Hand: - - T Ax

(3) Dummy: QT x x -
Hand: - - AKT x

I know your choice. I just copied your diagram to clarify my point.
NOTE: Trumps are 1-2, since we have ten of them.

Ruffing a minor does not look right to me. As Benoit Lessard diagrammed above, in the 5 card ending, say, we have
the following.

QT
x
x
x

-
-
AKT
Ax

If East has both minors guarded (and K with West), we should not ruff anything but play the last . However, in that case, we will lose some bigger chances. So, it seems better to decide earlier in which minor suit to keep an entry to the hand, and play accordingly.

I am not a mathematician, but doing the math using the calculator in “TT's bridge site” (with which I find it easy to handle vacant spaces). Of course, I will give results in detail here.

After my wrong analysis, I looked through the deal more carefully.

(1) I think that (as Kit Woolsey suggests) it is best to go to dummy's A before cashing Q.

(2) When South wins K and returns a , we ruff in dummy. Now, we play a small trump to hand and, say, we see that trumps are 3-2 (or 2-3).
At this point, we should decide which suit, s or s, are split 4-3 (or 3-4). I don't think that we have a play to cover both.

Then, still, South's return may not be a mistake, but a good (misleading) defensive play.

I noticed that my analysis was wrong.

I like the 2nd hand as a single-dummy problem in the context of combining the chances. And I agree that the line you suggest seems to be the best.

Thanks a lot, Steve. I hope to find and convey more tales; however, it's not only up to me, it has a lot to do with the people around who make our game more attractive and enjoyable…

If East discards four s, three s and one , can the declarer be convinced that East has 6-2-5-0?
That seems to be the only way to mislead the declarer. Yet, to do that, West needs to give wrong counts in both s and s, which is not easy. And I am still not sure if such an attentive declarer falls into that trap.

I hope next time you can find a competitive and friendly team match.

0) The reasons are like those in similar areas. Being successful at the top level requires dedication while somewhat disregarding other parts of life. Women don't have the chance to do it as easily as men do.

(I asked this question to my wife, and this is her answer. She also noted the relation to the ego: Women are not brought up feeling superior to others… I agree with her on these.)

The quantity has also a bearing. The total number of women who get acquainted with the game is much lower than that of men. In addition, it may not be so easy for women to find appropriate environment and places to go after such an activity.

1) Discrimination against women.

2) I am not sure. Probably yes, but in that respect, it may not be very different from discrimination against men with much money and little talent. This is seemingly positive, yet, not so in essence.

3) To belittle her as partner, team mate, or opponent; only because she is a woman.

4) There is a general tendency that women are bad at certain things; however, I believe that it should also be included into sexism.

5) Introduce bridge to all children as early as possible, and create environments in which they all can pursue their hobbies or passions.

6) Although I don't find it necessary, I don't see any negative side of it.

7) Not for the time being.

8) Male

Luckily it has not taken longer than 10 days since the deal came up on the 15th. Frankly Kursat, until the idea of removing all the spot cards came to my mind, I had had a hard time clarifying things.

Surely so. Yet, I don't know the bidding and who the bidders are. It was a 48-team event. One of my teammates conveyed the hand to me. Anyway I don't think it would be a likeable one.

If one has 3-4-3-3, A will not drop in three rounds.

I don't know. I didn't wonder about the bidding.
