the simulation was meant to find what happens when opener has the worst fit minimum hands, how will a heart contract end up with.
yes, we realize the simulation can be improved.

if opener has 5134 and 15, he would not pass and that was not the simulation goal.

The point is this:

If you respond 1NT, you risk a pass from opener when he has flat min hand and miss game.
If partner would rebid, then what you bid first is less of a concern. You will always reach game if there is one and you might reach slam if he shows fit in either red suit.

Actually, to be closer to the style of most playing 1NT semi-forcing, we should have asked the simulation to be done for 12-13 5(332) hands.

Good point.
I was on defense, thus forgot about this important issue.
NS plays semi-forcing, but it is more like 95% forcing.
Opener may pass with minimum flat hand that has 7+ losers.

That is how I play.
But most people did not play that way (at least among my partners/teammates/friends, they do it only when I force them to), thus I did not make that a choice.

1m-2m is inverted minor promising 5-card support, limit raise or better.
1m-2m-3m shows minimum and wants to stop.

Richard beat me in answering this.
That was why we play kickback for H but minorwwod for minors.

@Max
I know it was not about me or my partner, I had never took our discussion personally.

I guess we will just have to agree to disagree.
I strongly feel UI with a non-pass bid are different to UI with a pass.

@David @Richard
Not sure what I had missed but I had stated in the original post that North (yes, that was me) was thinking about how to invite.
My thoughts had been the same since I made the post, never changed by David or anyone else.

Max,

Let us just take this hand in the post as an example.

I was North and had determined to invite all along.
My issue was which is the better bid to invite, 3D or 2NT.
So the bidding issue may be not just about a simple weak invite or strong invite.

Even if the issue is as simple as weak vs strong invite, a lot of other factors could affect the decision:
- type of game
- stage of the game (is this last board in a tight swiss or in a game you are leading a lot)
- your opponent's skill level (is that Kit or Max (just kidding) sitting West?)
- partner's declaration skill
- is partner an optimist who accepts frequently

My point is simply this, nothing is as black and white as one may think.
You may know your partner is an optimist but you do not know what is going through his mind to affect his decision. Being an optimist can invite with a weak hand that others would have passed, if you bid 3NT based on he is an optimist and not based on your own hand, you will probably just lose more.

Max, I beg to differ.

Let us say my partner is an optimist, I open 1NT and he bid 2NT to invite in tempo, I would be pretty certain he is within 7.5 to 8.5 point range.

Being an optimist, I knew he would bid game without invite if he has a good 9.

But if he huddled, he could be deciding between pass and invite with a good 7.5?
xx xxx JT9x KQJx

or deciding between invite and bid game directly when he has not-so-good 9?
xx Jxx Qxxx KQJx


* Feel free to adjust the hands above to fit the description according to your style.


UI with a pass carries a more definite message. The law should be enforced fully.

But UI with an invitation bid is not so certain. The partner should have more freedom in follow-up bidding.

Max,

“Some don't like it because it would hurt them”

I would think at lower level of games, there is very few, if any, would cheat.
People would leave the game of bridge because they got very bad experiences being treated like cheaters, not because they cheat and got caught!

“I strongly believe that tons of UI is passed and acted on”

I could not agree more. When you pass after a long pause, there is only 1 direction for your pause. You wanted to bid up but decided not to. Partner can use the UI information.

However, in the bidding from this post, North made a non-pass invitation bid. South could not tell if North wanted to pass, to invite, or to go to bid game. In another word, there is UI but the direction is unclear. Everyone knows there is a bidding problem for North, but no one knows he wants to go up, prefers to stop, or have a hard time pick the right bid to invite.

I would hate to see EW calling the director, set the scenario of long pause.
It is like EW getting a free pass, no matter what South decides to bid, he would be in a no-win situation.
If he bid pass but 3NT would go down, some can argue he was supposed to bid on without the UI.
If he bid 3NT and made it, the same people can argue he went to game with the UI and roll it back to 3D making.
But if he bid pass and 3NT would make, or he bid 3NT and went down, he will have to swallow the bad result.

I just do not fee fair to enforce the law as some people suggested.
And I am very glad to see majority of people who care to share their opinion has an open mind.

Added when there are 10 votes for 2S and 3 for Pass.

To those who passed, have you considered this is a 5 loser hand and you only need any 2 of the following cards (SA, SQ, HA, HK, CA) to make 4S?
Of course, partner must have 4 spades too. If he does not, he would pass 2S.

For this board, 3D can be made, but was that the right argument for South to compete?
I think that was putting cart in front of the horse.

Without looking at the other hands, I think David was right to judge 3D can be defeated.

- South has value in opponent's suit (more defense than offense),
- South has only 3 trumps (more defense tricks but less offense tricks in spade).
- South has no short, 4432 is also more defense than offense.
- South has less than a constructive raise, should not he has extra to violate LOTT?


North would be happier to see a hand like xxxx QJxxxx x xx from South, which is less in point strength but a lot more in offense.

“Trumps and losers/cover cards matter as much or more than points.”

I could not agree more.

When East had opened 1C, you think Kxxxxx in their suit is useful?
May be xxxx QJxxxx x xx would be more likely?

With that hand, North only need to find SQ to make 4S.

Agreed, however…

Of course, Bridge is a game of probability/chances, nothing is absolutely right.
The issue is which bid (Pass X, 2C, or 2H) gives you best chance to be successful in the long term.

Looking at the actual hand/results is just to show that only 3 of 13 chose to pass.
This is pretty consistent with the poll result.

By switching the N and E hands, NS has an reasonable easy 1NT (or 2NT with slow defense).
Even so, EW playing DONT may stop at 2C -1 for a good score.
Even in worst case, EW playing Capp could stop at 3C -2, which will beat those allowing 1NT make 2.

If you play Multi-Landy, you do not need help.
If you do not play it, it is not relevant.

If you care to find out, you will google it.
If you do not care, I will not help someone who has no time or desire to help himself.

I have nothing more to say or time to waste on this.

Just in case someone is curious, here is the actual board.

http://www.paloaltobridge.com/gameresults/lorisue/C180418E.htm
Board 17.

Both sides has 9 card fit.

Only 3 out of 13 west passed and NS stopped at 2S safely. EW got near bottom or Ave-.

10 of 13 West competed with various results.

1 out of 13 west competed but allowed NS to make 3S. EW got share bottom.
1 out of 13 EW competed too high to 4H and went -2 undoubled. EW got Ave-.

6 out of 13 NS got pushed to 3S and -1. EW got Ave+.
1 out of 13 west won the contract at 2H and got near top.
1 out of NS went to 4S doubled -2. EW got top.

“it shouldn't be adequate for an article on this site.”

Respectfully I disagree.

I would not want to insult players reading this site by wasting bandwidth with detail descriptions of these very common conventions.
If someone did not know, he/she could simply google or ask (like some did here).

As far I can see, the only question was what X means in Multi-Landy/Woolsey.
There is a very good book you can buy on amazon (I thought it was sold on this site but could not find it now).
