“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 adding that fact to the inconsistent notes, is enough to provide team Rosenthal with full protection? I think they need to prove HOW they were damaged. Knowing the notes at the time of the bid is a pre-requisite to proof damage. There is no case without causation between the notes and the damage, that's all I am saying.

Under no circumstances is Migry the offending site, calling on the 5th is premature, but I appreciate the spirit.

“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 was in any way mislead by the notes into doubling, the rest is irrelevant. Adjustment makes perfect sense.

On the other hand, if Migry wasn't mislead by the notes in any way, then there is a very strong argument that the combination of double and 4S got what it deserves.

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 rules for invitations etc.

At each step I typically dump 100 hands which I review briefly to get some insights if I have missed something.

3 only if you are desperate to skew things. Likely against you. :)

4, and then 5 over 4. Hoping partner figures it out. The only way to find the 4-2 club fit with 9+ diamonds. ;)

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.

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?

A double on this round should show exactly my hand, illegal unfortunately.

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.

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.

Is 2NT too aggressive over 1?

The point is whether we reach 4. Partner had: AJ94 QJ8 AJ62 J2. South has a border line opening. When South opens 1, West overcalls 1 and East is in game.

5 or 6 on the previous round.

I share the same experience with respect to invitations and simulations. Especially at IMPs. If there is a better use for the invitation bid - go for it. Things get more even when one takes into account the contemporary style of opening many 14 hcp with 1NT.

My next bid is diamonds at the minimum level.

The odds are partner has 4/5 spades.
