Is there any statistics about success rate when opening 1n rather then 1 major.I commonly do it .I did it with s AJ6 h A10765 d K4 c K53 and afterward my expert right hand opponent sneered at the bid saying it was a 30% bid.I doubt that .Besides with a weak heart as in this instance I would have opened 1n even back in the days when I hardly ever did it with a 5 card major because the suit is week (I also would if the suit is very strong) .What do you think. smn

Did the 'expert' sneer because he received the poor result?
Opening 1NT solves the rebid problem.

It is a totally reasonable decision. I don't consider that Heart suit
weak but it is still reasonable to open the hand 1NT. Was the "expert"
wearing a sign saying "expert?" The reason I wouldn't open that hand
1NT is because I have no Strong NT partnerships anymore. I would have
opened it 1NT in the individual the other day.

I have no problem opening a five card major 1NT if the major is weak.
If the major is strong I prefer opening one of the major because if
partner has a fitting honor he will be more aggressive in accepting
game or slam because the major suit potentially can run.

Your hand is ideal for opening 1NT with a 5 card major.
1. You have 3 in the other major, so if pard transfers you will not
miss an 8 card fit.
2. Your major is hearts, so you shut out their spades (if they have
them)
3. A good percentage of your HCP are outside of your major.
Pard and I rarely open 1NT (strong) with a 5 card major, but with this
one I would not hesitate.

BTW there are many experts(real ones) who would open 1NT with any
5332 pattern and the right value range. Even with 2=5=3=3.

Look at Richard Pavlicek's website (www.rpbridge.net) where he has statistics comparing the imps gained/lost on hands which were opened 1M at one table and 1NT at the other. Opening 1H instead of 1NT is a big winner; opening 1S instead of 1NT much less so.

One obvious reason why this may be the case is that a 1NT opening prevents a 1S overcall (which makes 1NT more tempting with a doubleton spade).

On your sample hand I'd open 1H every time, because
- I play in a regular partnership with well-developed methods after a 1H opening. Inexperienced partnerships tend to find 1NT bidding easier as the system is well defined.

- It is a very suitable hand for suit play, with lots of controls and few intermediates. KQx QJ9xx KQx Kx is definitely a 1NT opening.

I dont know much.
I do not know whats the best opening bid with that hand
I do not know what is a 30% bid.
I do not know how to solve the troubles in the Middle East
But I do know that your right hand opponent was not an expert.

A good discussion, though 4 years old, also with statistics can be
found at
http://www.bridgebase.com/forums/topic/15252-5332-five-card-major-1nt-or-1m/

Pavliceks statistics though interesting are a bit dubious, because the
1NT covers all possible ranges, but opening 1NT when holding 12-14 and
a 5 card major has different considerations than when holding a strong
notrump.

This decision is often intertwined with system considerations
Personally I find it useful when playing 2/1 and partner opens with a
major and subsequently shows a balanced hand I can count on him being
12-14 or rarely 18-19, which he will clarify later in the bidding
anyway, but almost never 15-17. I find this helpful when considering
or rejecting slam bidding.
I am prepared to open most balanced hands with a 5 card major 1NT to
have this advantage, even if this incurs a small cost.
I also play a 1NT response to a major as semiforcing.
Again it is helpful if opener can not have a balanced hand in the
15-17 range and pass by opener is more common and his rebids are more
descriptive.

No, a 1NT opening prevents a 1S overcall. This can be very useful.

In one partnership I bid 1NT which we play as wide range.
In my usual partnership, we an artificial set of rebids.
See my comment above about having well-developed methods.

I bet that is not what is meant. The common idea that a 2533 pattern
is bad for 1NT because partner might transfer to Spades with exactly
five Spades and exactly three Hearts is more than offset by the fact
that opening 1NT will cause the opponents to miss their Spade fit
quite often.

In particular, there are two opponents, but only one partner, so twice
as much chance for spades to be their suit rather than partner's.

Thanks to all for the discussion and for the bridgebase and Pavlicec statistics.I see that I won't be opening a known inferior percentage bid if I continue to open 1n (15-17) with a 5 card major. One of my partners thinks strongly that one should have 3 spades (hearts) when opening 1n with 5 hearts(spades) but I don't usually have that restriction. After 1n-2c(stayman) Ijump to 3 in my 5 card major ,after 1n-2d (transfer) I jump to 3h (or 4h) with 5 hearts.
Where I have noticed inferior scores is when the bidding goes 1n-p-p-p and my partner has 6 or 7 hcp vs 1h-2h-p-p-p ,2h making 3. Regards smn

Look at Richard Pavlicek's website (www.rpbridge.net) where he has
statistics comparing the imps gained/lost on hands which were opened 1M at
one table and 1NT at the other. Opening 1H instead of 1NT is a big winner;
opening 1S instead of 1NT much less so.
-----------------------------------------------------------------------------------------------------------
I couldn't find those stats on his web site -- didn't appear to be under
Odds & Probability or various other headings -- were they in an article?

Unless I'm misreading the table on http://www.rpbridge.net/9x41.htm, it's "better" to open 1NT with 5 hearts, but 1S with 5 spades.

Yes, it says opening 1NT with 5 hearts did
better than opening 1H.

Pavlicek was restricted to posting only
the 100 boards with the largest swings.
The file size limited him to only 100 boards.

Open 1S vs. Open 1NT

Pavlicek posted 100 of the 183 boards in his sample.
W-L-T is win, lost, and tie.

In many of the examples the experts were opening
1NT with 5422. In two boards they open 1NT
with 6322.

A fairer test of 1S vs 1NT would be restricted
to only 5332 patterns.

Does the strength of the spade suit matter?
Are there enough data to indicate a minimum?
I seem to recall Bergen stating that one should always bid NT with a
5-card major and 5332 shape having 15-17 HCP.

A striking observation. Is your impression that the choice to open 1NT
on 6322 was systemic or judgment? If the latter, it suggests that
judgment for this decision is well worthwhile (i.e. open 1NT with
stoppers and/or weak (or should it be strong?) spade suit), and that
perhaps the poor performance of opening 1NT with five spades is
because most of those openings were made based on blind policy rather
than case-by-case evaluation.

A striking observation on a small sample.
What case-by-case evaluation would convince you to open a 6322 spade
hand with 1NT?

Actually in the three 6322 cases the IMP score was 4-1 in favor of
opening 1S. It was in the fifteen 5422 cases that for some reason 1NT
was most favorable (47-25). But I agree with Rainer that these are
extremely small sample sizes to be drawing conclusions. The main point
was that excluding all but the 5332 cases did not materially affect the
result.

Rainer maybe was reacting to my error. I referred specifically to 6322
because I read your message carelessly. I should have asked my
question about all the 18 cases. I suspect that people don't wantonly
open 1NT on 5242 distribution but rather pick their spots. However, an
IMP spread of 47-25 admittedly doesn't seem very significant and thus
doesn't tell us if the criteria that people use to pick their spots is
really effective or just superstition.

I _don't_ need to slip a spade into my clubs to justify opening 1NT when I have solid stopper in both 2-card suits. But I wouldn't consider jump-rebidding spades here - it's either open 1NT, or open 1S and rebid 2S.

I'd agree - with game-going hands, I believe we do better opening 1N with a five-card major, but I do see _many_ cases where partner passes 1N and would have raised 1M for a good result.

Ah, you are the first person to spot the typo in the original post.
It's supposed to say opening 1NT instead of 1H is a winner. (Oddly enough other posters seem to have read it the way I intended it rather than do anything boring like actually read what I wrote!)

Or open 1S and rebid 2NT. If partner has zero or one spade or two small all
the side cards are working well and the opps aren't likely to take many
spade tricks. If partner has Ax or Kx the suit may be establishable at
notrump. I suspect this hand evaluates closer to 18 value at notrump than
17.

Hmm, do you really play 2H a lot in these cases? I would think opener would
generally be worth a game try. If so, the comparison is between playing 1NT
and playing 3H, with the former usually safer at IMPs. Playing constructive
raises, of course, responder with 6 or 7 bids 1NT, then 2H, but then he also
does that with only two trumps -- and you'd generally rather be at 1NT or
3NT.

I wonder if a scheme of non-constructive raises (6-8) coupled with a gadget
2C would be worthwhile. 2C would be either a constructive hand (9-12, at
least two of opener's major) or generic game force (no five card suit other
than clubs.) The ACBL won't allow it, of course (the anti-Barry Crane rule),
but does anyone play that sorth of thing elsewhere?

So I suspect that the success/fail ratio for us when opening 1M would be better than for those who would have a problem rebidding with their 15-17 balanced hand.

Can anyone contradict this line of thinking?

I've played this way with weak NTs; with SNTs, I'd much rather use the 2NT
rebid as 12-14 or 18-19, and the jump to 3N as 15-17. Related issue: if 2N
shows extras, then 2M is the catch-all--and "lesser nuanced" partners seem
to have trouble with that structure at the 3 level.

Sorry, Scott...I seem to have confused you. I wasn't asking about the relative benefits of the 2 rebidding structure. My point was that one can't make head nor tail of the cited statistics without putting the statistics in context. My thesis is that the statistical results are likely to be different for those who use a 15-17/18 2NT rebid after 1M-2x than for those who use a 12-14 HCP range. Would you agree?

In my view, the statistics cited in this thread lack appropriate definition. Hence they cannot be relied upon...unless they were collected only from cases where a 12-14 range was in use. I have seen no evidence presented that that is the case.
