I agree that the auction took a favorable turn for those who open 1Nt but I still disagree with the 1Nt opener.

4 passes look normal. We already showed a desire to bid 4C when we bid 3S.

If you play a relay system its one of the first thing you learn 5-4 or 6-3/6-2 or Nt is fairly often better than 4-4 if you have wasted valuesi n the short suit or a side source of tricks.

I know most will bid 1 but I think that passing is probably better. I usually downgrade sing K in opps suits more than most players.

This is really the type of hands where you go -800 too often or -500 against a partscore.

If your partner got a good hand you might also be in a poor spot.

Strong dislike for 2, vul 2D should be an opening hand or at least very close to it.

just a little precision

“But since the pass suggests a minimum, balancer will
usually double.”

It more precise to say since the pass show no desire to play 5H rahter than a minimum sometimes you have extras but they are defensive.

Yes Craig you are 100% correct.

“My forcing pass with partner promises/implies either unexpressed extras or no wasted values in their (trump) suit. Doesn't that help us get to 5♥ when right?”

yes it does.

by old school I mean your NOT playing FP but you are playing penalty doubles, wich is still standard for many players but make little to no sense if you think about it. If your side didnt show enough values to play forcing pass its much better to sacrifice the penalty double and keep the dsip double than the other way around.

A side example lets say you have a 0535 with some extras (enough that 5H can make even in a 5-3 fit. Your obviously not too happy with defending 4S undoubled with a void and extras however reaching the 5 level on possibly 8 trumps is risky. So you are the one who should strive for action but responder is the one better placed to decided between defend and declare because hes the one with the lenght.

This whole discussion shouldnt be too complicated, but its somewhat complicated because quite often we are not comparing the same thing.

If you think that 4S will make too often than you probably don't need the X penality, so just play comp doubles

X= ask partner to choose between 5H and 4S (so show some desire to play 5H). 1633 is the classic type, your the one with short spades and extras so you should strive for action but responder is the one with the lenght so he is the one who is better placed to decided between defend or not.

pass = no desire to bid 5H, can be dead minimum, responder can still X for penalties.You dont need FP to help your partner choose between 4S and 5H (where its usually where there is most imps to win) comp doubles is good enough
———————————————-
What is truly losing imps is just playing old school.
X for pen and pass says nothing about the desire to play 5H.
When opener got extras that are both offensive and defensive (dsip hand) hes now forced to pick between X or 5H without consulting his partner. This is what Kit argument is all about, there is more imps in correctly deciding between 4S and 5H than imps penalty of 4Sx making/4Sxx minus the extras punitive pts you collect in 4Sx going minus.
————————-
So to simplfy

if you think 4S could make and 5H can make or is likely to be cheap just play comp double

if you think its unlikely 4S could make or that a good penalty can be made out of 4Sx just play FP or reg FP

If you think you might be outgunned, 4S can easily make and 5Hx can be costly just play old school.

What is most important is that old school is not a good method when your close to make 5H.

The simplest way ive found to explain FP to my students is this.

(1)- If you play FP with inversion.

pass = pen
X = DSIP, choose between 5H and 4Sx

(2)- if you play comp doubles or semi-pen doubles

pass = little or no interest in 5H, responder can X for pen or not.
X = dsip,extras ask to choose between 5H and 4Sx

(3)- If you play reg FP
pass = dsip
X = pen/little or no interest in 5H

(4)-if you play old school

X= pen
pass = may or may not have desire for 5H.

——–pros and cons
(1)- lose the ability to play 4S non-doubled. better slam exploration.

(2)- lose the pen X by opener (responder can still X knowing opening is not interested in 5H.)

(3)- same as 1 except that responder can sometimes chicken out but you lose slam exploration.

(4)- you lose a way to force partner between 4S and 5H. If opener got extras hes often force to X or bid 5H since he doesnt want to play 4S undoubled.

———————-
(1) is to be avoided when they can easily make 4S and 5Hx might be too costly. Outgunned or wild hand.

(2)- is to be avoided when 4Sx go down 2or3 too often and its opener that got the def extras. When your top dog.

(3) same as one

(4) is imo inferior to (2) vs decent opponents. Probably best with less experienced players where any of the 4 players can make overbids. (4) is good when its not clear who has the upper hand or when the number are tricks have high variance (hard to predict)

if the hand can be a big double fit leading to 5H making/4Sx +1 but if you switch the minors its really bad breaks in side suits and both side gown down.

I always play (1) or (2). Here our 2S didnt promise a lot of defense so we would play (2).

I did the sim because i was surprised 80+% bid 4H. I tough it would be 60-40 or closer.

No, east is a passed hand and we are NV so its unlikely to matter.

What I did for the first sim (52%-48%) is ive put wide parameter. Ex preemptor could have only 5 pts but could have an opening (hes facing a passed hand) for his preempts and overcaller could have only 10pts for his 3H bids, I do this because sometimes preemptor got void,x,T9xx,AJT9xxxx. and sometimes declarer got a super 10 count. Ive also bid 4H on hand where i felt 4H is a better bid then 3H even with some 17-18 count.

Ive remove hand where East would have preempted/or any bid, where its not really a 3C bid (too weak or too good and afraid to miss game) where its not a 3H bid.

With these parameter its very close and maybe DD is too much in favor for declarer.

I did took a lot of time to do this to get only 200 hands so I think game is 52% with plus or minus 4-5%. In MP there is a strong case to bid 3H lighter (than in imps) so maybe in MP passing is best. But if my partner bid 3H as if he was in imps i would bid 4H even in MP.

Thanks.

It would have surprised me that we are not able to open 1Nt with a singleton in the RR but we are able to play FP in the KO phase (HUM are permitted in the CNTC but only in Bermuda bowl years)

“B. CONVENTIONS
1. Conventions in the ACBL General Convention Chart will be allowed at all stages of competition.
2. In the National Final Stage I and II for Flight A, ACBL Superchart will be permitted. ”

“. In the knockout portion of the CNTC-A National Final in Bermuda Bowl years, any system or convention
including HUM systems, will be permitted if a typewritten description and suggested defences are submitted

“designated it as a special partnership understanding if it has certain shapes (or HCP ranges).”

As i understand it the Acbl made a clear definition of what is a natural 1Nt, but what about non-natural NT that are not weak and not destructive ? Does the superchart forbid 1NT with a long unknown minor (not weak) or unusual range (at least 8+) ?

When you have there is no need for a bar bid.

Both opps have already passed once so they wont fight to the 3 level too often. Sometimes they will need to balance over 1S and the extra information you get will allow declarer to make 2S.

In std double and cue tend to deny a fit (some play X and cue as 100% GF) however I think it make sense that 2H can be a a very good raise wich would allow 2S to be bid on lighter values.

CNTC (canadian championship) is in May 2018, im not asking for a change in the rules im asking for where are the laws that applies for a 1NT opening not natural.

Ex can you play 1NT as a mini roman, short in one minor and at least 3 in the others suits ?

What i play is similar to Molson but ive never understood why it use canape ?

what i play
X= 5M+os (can be both maj)
2m = 5m+4M
2M natural
(compared to Molson we lose the club singlesuiter but we get to the right majors when its 54 vs 33/22)

when we are 54 we know wich suit is longer and you are able to stop in 2m. If 2M is canape you might be stuck in 3m in a 5-2 fit.

also some gambling 3nt hands need to be removed, some hands where east would raise to 4C (these hand are usally 4H making because overcaller is going to have a void).

IRL my partner made a slow pass and I played 3H+1 and it was totally cold. The other table raise to 4H I had some extras for my 3H overcall.

with these numbers its 65%–35%.

Note that IRL some 55?? will be michaels or 3S bids, those 55?? 16-19 will almsot never go down in 4H.

Many 4531/3541 will be X.

And you range are quite high compared to mine. Imo few will pass with 15pts and 5H and not uncommon to see 3H bids with 11pts and a 64.

I still think game should be bid at all form of scoring but its close if passing is your biggest mistake of the day you have a great game.
