Like most in the poll, I chose to Double also. On this hand, the 3NT bidders will make Partner's life easy, as Partner's hand was QJxx/JTx/Axxx/xx. After my Double, he had to guess what to do next.

Declarer had 9764 T8 K9753 AQ, so this was my only chance to signal to Partner that he needs to win his A on the first or second round and lay down his K.

I chose to play the T. The poll results are very interesting and I can understand why the majority thinks the 9 is the better play.

Thanks Michael, Mike, and others for sharing your valuable insight.

Thanks, I did not know about the hand diagram generator. That is much better!

I don't know what 4 is here. I guess it depends if you treat the 2 opening like a 1 opening or a 2 opening. I can see merits for either method, although my inclination is to lean towards treating it like a 1 opening.

Partner had 4 T A643 A987542.
LHO had QJ9732 Q843 QJ5 -.
RHO had AK85 95 T982 JT6.

With careful play, the hand makes 6C. With best defense, the hand only makes 3H.

I was interested to see if people:
A) Give up on hearts and support clubs
B) Bid the hearts since it is BAM or
C) Pass. It would be interesting to see what the Passers would do if Partner doubled or if Partner bid 5C.

Thanks all for chiming in, the poll results were interesting and helpful to me.

Thanks all for your insightful comments, especially Leonard and Reid for sharing the Garbage Stayman Simulation analysis. Very interesting stuff!

I held this hand when playing with Brad and chose to do Drop Dead Stayman based on experience and a hunch (and I like to gamble!). It will be nice to have the numerical analysis referenced above to help with these decisions in the future.

Partner had Kxxx Axx Kx Q8xx. Both part-scores are making since the A is onside. On defense against 3, we got 2, 1, and 1.

I was right that they had 9 hearts and we had 8 spades. I was worried Partner had wastage in hearts, so I also passed. After the hand was over, I was a little mad at myself for not bidding 3S.

I posted the poll to see if I took the percentage action or if I made a minor error. The poll (43 passers, 7 3 bidders) seems to think I took the percentage action, but I contend that I made an error as I think all the conditions for 3 over 3 are there:

Conditions:
1. There are probably 17 trumps. I didn’t post this info, but my LHO insta-bid 3H. If Partner had the same read, she knows I have a stiff heart and maybe she should bid 3S since she is looking at Axx of hearts instead of KJx.
2. Both sides have a double fit as it is more likely Partner’s values are in clubs instead of diamonds.
3. The hand is probably pure (not much soft defensive values).

Scenarios:
1. Neither 3H or 3S makes. Bidding will cost 3-4 imps.
2. 3H makes but 3S goes down. Bidding will probably win 3 imps.
3. 3S makes and 3H does down. Bidding will probably win 3 imps.
4. Both 3H & 3S make. Bidding will win 7 imps.

Teammates were also +140, so the board was a push, but in my eye it was a lost chance to win 7 imps.

Still, the four of us got many hands right in the Hunt Valley Swiss and we came 4th out of 35.

Thanks to all who participated in this poll.

Bob, did you notice that 1NT is 10-13 HCP, not strong?

We play systems on over 2C interference, so I really didn't have any other options other than pass of 2C. I could have doubled which is Staymanish, but I would not be prepared to handle a 2H response.

In case Overcaller's suit is diamonds, Partner does a takeout double of the artificial 2 bid that might be passed by Overcaller. Partner's shape is something like 4423 or 4324 or 3424.

Most of my partners and I play that Double is takeout of any artificial bid that is non-forcing. Another way to phrase it is “Double of a pass or correct bid is takeout”.

The Double does not show any extra values. It is strictly a shape-showing bid.

This method is much better than lead-directing doubles in this situation, as it allows you to find a playable trump suit at the 2 level so you can compete for the part-score.

According to the calculator out at (Google “vacant spaces odds table”) going with the assumption the diamonds are 5-2 (Give West 8 missing spaces and East 11 missing spaces), 17.702% of the time the Defense can run 5 heart tricks and 15.065% of the time they can run 4 heart tricks. The other 67% of the time the 8 will emerge as a 4th round stopper or the hearts are blocked and the Defense has to untangle their 4 or 5 tricks.

It seems at imps that the best line of play is to duck a heart at trick #2 and invite the Opponents to cash their hearts. Afterwards, hopefully a ninth trick will be from clubs coming in, the Q dropping, or a squeeze.

With such a good hand in the context of prior bidding, pass is not a logical alternative for Opener and he should be allowed to bid again no matter how much break in tempo. Even opposite a bare bones slam invite such as AKx Qxx KQxx KJx, 6NT is cold as ice. My guess is Responder's hand was better than this, and 6NT made easily.

Thanks for you insight Richard. In case you didn't notice my 2/22/16 post, that has what actually happened at the table.

Thanks for sharing your insight. At the table I went with my first instinct and insta-bid 5S, hoping it would make or Opps wouldn't double. After posting this problem and reflecting further, I think my stiff HQ, Kx of diamonds, and K98xx of clubs should say to play defense. If Partner has xxxxx KJxxx x xx, we still may set 5D even if they ruff the first spade.

This hand occurred in the Washington Bridge League sectional open flight. I bid 5S and Partner put down: Jxxxx 9xxxx x Qx. I should be able to figure out he has something like this since the Opps probably have at most 7 hearts and I only have one. My stiff Q opposite his heart length and his probable club shortness opposite my club length will be good for defense, so I think I should have Doubled instead of bidding 5S. Bidding 5S will win a lot if RHO has a spade void and they make 5D. Bidding 5S should win a little if you hit Partner with Ax of clubs and making 5S is more than doubling 5D. Double wins out on almost all other cases.

After I bid 5S, I got doubled by RHO since he had the other three aces and I was -200. 5D would also be down one since my RHO was 1-4-6-2. Our teammates were allowed to play 4 diamonds and were +130.

Double wins 8 imps, Pass wins 6 imps, and 5S loses 2 imps. Interesting to see how the current tally is 22 votes for Pass, 20 votes for 5S, and 16 votes for Double.

Thanks all for your participation.

Partner had KTxx xx AKxxx xx. I wanted to Double, but I was worried Partner would think it was Snapdragon instead of “Negative”. I chose to bid 2D hoping to buy the hand at 3D after they bid 2H and also give us a chance to find our spade fit. If they were red, I would bid 3C or 3D to get to the three-level right away. Anyway, right or wrong my 2D bid worked out well, as it went

(1C)-1D-(1H)-2D
(2H)-P-(P)-2S
(P)-P-(3H)-P
(P)-3S-(All Pass)

The Opps can make exactly 3H. We were +140 in 3S for a win on the board.

I thought Double shows four spades and 1S shows five spades, but I wasn't sure what was standard and my Partner and I have never discussed this situation.

It is interesting to see the early poll results and how six bids have been mentioned!

After two days of polling, I will post what actually happened.

I thought of bidding 3D, but I was worried if I tell the NV opponents that we are on a 9-fit, they will be more likely to bid 3H over 3D, which I don't want to hear.

If they were vulnerable, I think bidding 3D has more merit.
