Thanks, found the article. Will use it in the future.

Did you mean “with a bad hand for slam, bid 4M”?

This situation hasn't come up often in our partnership so we don't have an adequate method to handle it. I transferred to Spades and then bid Hearts knowing it could be passed. Partner took a preference to Spades and I then bid a Spade slam which was easy to make.

There could easily have been a Heart slam which we would not find.

We were able to make 680 while most made 650. Opponents received 1 out of 6 matchpoints while their overall average was 53%. So if a “no play” was given then their result would have improved.

Opener's LHO passed without much hesitation so it's probably the case she was passing to the 1NT original bid. No player stated they actually saw the 1C bid placed on top of the 1NT bid.

The 1 card was on top of the pile. I should have realized that if the 1 bid was actually bid, there would be no other cards underneath it. But I was not that clever at the time.
If I trusted my memory more than my eyesight, I would have called the director immediately. My LHO called as soon as I laid my 1 card down.

Thanks Ed, if 4 over 4 shows some interest in slam, then do you have a use for 4 when Spades have been chosen?
1NT 2 2 4 4

But 4 is artificial so only 3 suits have been bid. Is a Club control being shown in either auction?

How many sets of boards do you make up?

What do partnerships with 3M and 6m do when partner opens 1NT? Seems like a conflict between puppet and 4-way transfers?

Since this player is not active on BW, let me counter some of these arguments:

Assuming responder does not have a garbage hand:

1. Opener's 15-17 count becomes 16-18 because of a length point in the major. So he doesn't not have that bad “15” count.

2. What strains are available besides 3NT, 3M, 4M? With five in a major, playing in 4m or 5m will seldom be advantageous. One loses playing in 2NT but many of the other systems here have that problem too.

3. If responder has 5-2 in the majors, he would Jacoby transfer so losing 5-3 strain in the OM should not occur.

4. Will any of the conventions posted here, prevent a 5-1 fit in the major from being played in 3NT when the points are there.

With garbage Stayman hands, most of the systems described here will be at the 3 level with a 5-4 fit. 2C puppet is the exception. So this is the major advantage of 2C puppet as far as I can see.

I asked our club's top ranking player what treatment he uses when biding 1NT with a five card major. His approach is to jump in his major when partner bids 2C. He argues when partner has a garbage stayman hand then they have found a 9-card trump suit so he is not too worried. He does this for both majors and with any 15-17 point range.

He says he has a lot of success with this approach with only a few failures. Probably worth some simulation runs.

Are you showing 5-5 minors when bidding 1NT-3C and 1NT-3D?

In the following auction, does 3D ask for the major if partner has one?

1N-2N-3C-3D?
2N= asking about a 5-card major.
3C= don't have one, but may have a 4-card major.
3D= what do you have?

I wish. “He” is my partner. I have not found any articles on this. Does anyone know who Bell is/was?

The way he described Bell was: Over 2C Stayman, 2NT = 5-card major min, 3M = 5-card major with max. Others use 3C for 5M and max. I'm sure there are other variations

Excellent Doug!
So just having 2 Aces and no tens, one should never invite with 4432 hands (23% making game). Correct?

But KnR is saying two Aces is worth 9 points which is probably invitational to most players. So if one invites, the 16 point notrump partner will accept and we're in a 23% game.

Amazing that taking away the tens and nines will lower the probability from 66% to 23%.

What simulator are you using?

Actually the simulations I would like to see are:
1. North has 16-17 points so game is bid on every shuffle.
2. South has 8 points with two Aces, 2 four-card suits and no tens.
3. Same with 2 tens.
4. Repeat 1-3 with one or both suits being a major.

I would be interested in how many shuffles produce 9+ tricks in notrump or 10+ tricks in a major.

I didn't consider tens and nines which was clearly an error as most are using these cards for their evaluations. My partnership doesn't open 1NT with a 5 card major so I was being a little selfish here.

But I'm very happy with the comments and they will change some of my ideas.
