Sorry, this user has no cards yet.
Double Standards
"It would be entirely open to her to say that she doubled because the written defence prescribed that she double." If there was no 3S opening, but team Rosenthal found out the inconsistent notes, were they entitled to a few IMPS? NO I hope. Now, 3S came up, and just ...
Double Standards
"Before Doubling, Migry asked what 3s opening was and was told "Gambling 3N solid minor, nothing outside" Was Migry mislead, in any way, by the notes? It sounds she didn't consult them, but she might have remembered from a previous scan (or board). The point is that if Migry ...
Mathematically, when should you make a game try (and which one)?
Pretty much your approach. I would start with the simplest option: 1M 3M. Now, there are two possible contracts 3M and 4M. DD analysis, each hand considered at a fixed vul setting. Comparing accepting vs not. Once this works, move to different vuls. Once that's done, start encoding simple ...
Jeff Ford's bidding problem: J65 Q64 3 KT9732
3 only if you are desperate to skew things. Likely against you. :)
Rae Murbach's bidding problem: J53 T5 A862 KQ73
4, and then 5 over 4. Hoping partner figures it out. The only way to find the 4-2 club fit with 9+ diamonds. ;)
Jeff Ford's bidding problem: AQ JT973 KT K876
Same experience with simulations of similar situations. My approach is Stayman. If relays are available after Stayman, ask to ensure partner is not 4432/5332 before blasting to 4H.
Nikolay Yaninski's bidding problem: AQJxxx T8xx x xx
From a quick and dirty simulation for nine card, and longer, fits: * Only 9-card spade fit: around 39% * Only 9-card heart fit: around 9% * 9-card fits in both spades and hearts: 3% Based on the above, does it feel ok to (likely) bury the heart fit - 9% of the time?
Yuan Shen's bidding problem: KT865 J3 AJT32 J
A double on this round should show exactly my hand, illegal unfortunately.
Do you consider this pass forcing?
We bid game. We also demonstrated that we don't have the usual HCP strength for 3NT. The 2D bid is limited, so is the 3D bid. Not to mention the 3D bidder passed originally. All this is not sufficient to setup a forcing pass at any vul IMO.
Major Disagreement with NT Interference
What Martin suggested looks like a good compromise to have it both ways. But you are free to continue fighting it out with partner based on this poll.
