IAC & Master Solvers Club / Re: 2020 January - MASTER SOLVERS CLUB
« on: December 21, 2019, 01:40:36 AM »
January solutions.
The Director for January was David Berkowitz

Snippets from the panel:

PROBLEM A: Double. The runaway majority choice.
Rodwell summarized his thinking with, “Double. I very much prefer minimum equal-level conversions only from clubs to diamonds. I’ll need to bid diamonds over clubs, overbidding a bit, but there is too much heart potential to be happy overcalling two diamonds. I almost prefer one notrump to two diamonds.”

And . . .
John Carruthers, “Double. Despite the footnote. Dangerous, agreed, but just a little length in a red suit opposite will offer some protection against disaster.”

A distant second was 2 !D

Both Jack and I got this one, not a popular answer among the IAC gang.

PROBLEM B: 3NT. Not quite the majority I expected, although 3NT was the winning selection.

Kit Woolsey echoed my thinking with, “Three notrump. Driving this hand to game can’t be terrible, even at matchpoints. Since there is a bid that describes the hand-type perfectly, why not use it?”

I found myself nodding in agreement with Berkowitz’ warning following the 3NT bidders’ comments. He states, “The trouble with the three-notrump call is that it screams for a spade lead.” Good visualization!   

The other game-force bids [3 !H is an underbid and underbids rarely win the cheese in a bidding contest] were a 3 !C jump-shift and no-nonsense jump to game with 4 !H .

Regarding 4 !H Michael Rosenberg explained: “Four hearts. Short a heart, but long on values, so should be okay. I guess three clubs would also be okay if partner made allowance for this hand type. (I prefer it to guarantee at least four clubs.) Three notrump might be a better contract or not—no way to be sure—but bidding three notrump might induce a spade lead, exactly what I don’t want. Three hearts feels like a clear undercooking—could bid that without the heart queen, maybe without the heart king. Two notrump would be both undercooked and misdirected.” Although in the minority, Rosenberg’s detailed analysis is spot-on.


PROBLEM C: 3 !H . A majority.

Most of our participants also chose this, so I’ll not linger on the reasoning.

2 !H was the second place vote-getter. Bobby Wolff, who chose 2 !H , thought (at least initially) along the same lines that I did, but he went low anyway, while I chose 3 !H . Wolff: “Two hearts. Yes, I know that the opponents may now outbid us in a suit that figures to fit better than spades . . . .

Interestingly, there were a few mentions of Pass as an alternative, but only one panelist chose that route.


PROBLEM D: Redouble. A close call over 1NT.

I must admit to counting beans here, thinking the hand short of the values required for redouble (I chose 1NT). Several panelists even mentioned it was short of the values for redouble. But that is often what makes a good MSC problem: right on shape or some other aspect, short values or expected length.

I did like the flexibility of redouble, as did four of our participants. Kudos to our redoublers: Wackojack, Draculea, Curls77, and Toasterln.


PROBLEM E: 1 !D ; 2 !H . Another majority.

Larry Cohen summarized his thinking: “1 !D ; 2 !H . Not thrilled with having only three hearts, but showing strength with the red suits most closely describes the hand.”

Berkowitz added: “Holding only three heats is no problem, because we will always reach spades should partner raise hearts.”


PROBLEM F: 2 !H . Almost a majority. There were only three options chosen by the panel; 2 !H , Double, and 3 !H .

The “slow” 2 !H won the day.
•   Woolsey: “Two hearts. Go slowly.”
•   Cohen: “Two hearts. The fun has just begun.”
•   Rodwell: “Two hearts. See what develops.”

Hoki and GG_Bridge were our only participants to nail this problem.


PROBLEM G: 2NT. This was close. 2 !D was only one vote back and Pass! close behind that.

Woolsey: “Two Notrump. The right value bid. Our most likely game is three notrump, and if partner is minimal and passes, two notrump is probably right.”

Zia: “Two notrump. I would like to bid two diamonds, but then I would need to bid three notrump over three clubs.”


PROBLEM H: !D A. The runway winner, garnering a majority. Why?

Michael Rosenberg summed it up best with: “Diamond Ace. A gamble on the diamond king’s being somewhere other than in declarer’s hand. I hope that the sight of dummy will help me know what to do next.”

And Cohen, only somewhat jokingly: “Diamond Ace. To see what I should have led.”

The !S 2 and !C Ace were next in receiving panel votes. And although the !D Ace was the majority choice, there were quite a few panelist who agreed with the pure guesswork involved with opening leads. So if you got this one right . . . GOOD GUESS!

Some additional observations on PROBLEM E.

PROBLEM E: IMPs
East-West Vulnerable
You, South, hold:
!S 863 !H AQ7 !D AKQ954 !C K

Which of these plans do you prefer?
(a) open 2 NT

(b) open 1 !D ;
then, after (Pass) - 1 !S - (Pass) - ??
   (b1) 2 !H
   (b2) 2 NT
   (b3) 3 !D
   (b4) 3 NT



This is another variation on The Bridge World "Death Hand." Six cards in my suit, three cards in partner's suit, extra values. Usually, the other three card suit is the other minor, and the recent trend in panel votes (I've seen it three times in 24 months) seems to be toward staying low. This one is a bit different in that it's a two-part question and our three card suit is a major being dangled in front of us as an option, something I may have done once in my life. I simply don't do it.

Not that this changes my choice--this time--to reverse into a three card major. Simply an observation in the similarity with other "Bridge World Death Hands" we have seen in the MSC.

Lots of information on The Bridge World "Death Hand" on the internet for those who wish to research it. I spent an afternoon a year ago digging into some of the mentions.

A new year! A fresh start!

My initial January guesses:

PROBLEM A: Double. Although 1NT is right on values, it has two flaws: the stiff King and a dubious stopper. 2 !D is tempting, and although BWS does not recognize ELC here, I’m still doubling.

PROBLEM B: 3NT. Fits the definition. If we belong in hearts, partner will know and can correct.

PROBLEM C: 3 !H . Somewhat of a tossup between 2 !H and 3 !H . I’ll go with 3 !H to both convey the nature of my hand (keeping alive our slim shot at game) and to preempt the opps from finding their probable minor fit.

PROBLEM D: 1NT. No need to introduce the !S suit. This conveys more information than the alternatives.

PROBLEM E: 1 !D ; 2 !H . If I “fake” a reverse or jump-shift, I prefer that it be a minor. But I want to force, so I reluctantly reverse into a major. There is a degree of safety here since I have three spades. Partner will most assuredly not support hearts with only three (though I suppose there is an exception), so if he does support, I’ll know he has five spades and I can correct to our spade “fit.”

PROBLEM F: 3 !H . Fit jump. The !H is threadbare, but the extra, unexpected !H somewhat makes up for the lack of honors. Second choice is double.

PROBLEM G: 2NT. Tough choice. 2 !D a close second. This one was very difficult choice and I am not remotely confident.
 
PROBLEM H: !D A. Opening leads are tough. But I’ve got everything in !D except the King, and partner is doubling. This bodes well for not blowing a trick and carries the added bonus of getting a peek at dummy before taking further action.


No change of heart. Submitted the above choices.

Hi,
I've submitted my answers to Bridge World for the first time.  I've read the posts about how this works, but not quite sure if others will see my answers if I don't post them in the forum.  I decided to answer all the questions without reading what anyone else had posted as to their answers.

Am I supposed to put my answers up before the contest ends?  I don't mind if others see my answers.

Charlene (GG_Bridge)

Great, Charlene. Welcome to our little IAC MSC forum.  :)

It's up to you how you want to handle this. If you don't mind others seeing your choices, by all means post to this forum. If you want privacy, then message or email your responses to Jim or to me.

To post here you can simply copy and paste the email response you received from The Bridge World. Also, feel free to chime in with your thoughts as to why you chose the way you did. Again, that's up to you.

GOOD LUCK!

As far as alternatives go on problem B, I see several. 2 !C -- 3 !C -- 3 !H -- 3NT -- 4 !H

All possible. All viable. Possibly all receiving panel votes! Which makes it a good MSC problem.

But if you're not going to rebid 3NT on this hand, knowing the BWS definition, then why define the bid as such?

I like to start with the low-hanging fruit, the easy ones.  ;)

PROBLEM B: 3NT

Like Jim, I hesitate to allow the *BWS blurb to influence me, but isn't this a textbook 3NT?

It scares me that we're all in lockstep on this one.

Sleight of Hand / Re: Would you double and what is your lead?
« on: November 26, 2019, 02:40:12 PM »
I agree with Ken, I would not double. Regardless of the form of scoring. Nothing about this hand (or auction) indicates a double is warranted.

That said, the only suits to lead are trump and hearts. I would choose the !H King. My second choice would be a small !S .

« on: November 16, 2019, 07:17:29 PM »
My Bridge World arrived so I've added some panel opinions below.
The director for November was Danny Kleinman.

A few snippets from the panel:

PROBLEM A: 2 !D was the runaway winner on the first problem, garnering 17 of the 28 votes.
There were two panelists who chose 2 !C ; Kleinman summarizing that choice with, “Two clubs by a passed hand scares me. Because it’s non-forcing, the sine qua non of a two-over-one by a passed hand is a good suit, playable opposite a low doubleton or a good singleton honor.” Yup.

Six others chose the “flexible” double. Woolsey, Levitina, and Hudecek, all doublers were very concerned about partner having four hearts—either hoping to get away with playing in a 4-3 fit or planning to correct to diamonds. Kleinman echoed one of my concerns with, “What scares me as much as anything is that partner has four hearts and more than a minimum. Do you plan to correct three or even four hearts to diamonds?

Finally, Bramley stated the views of the majority best stating, “Two diamonds. Being short a diamond is less misdescriptive than doubling short a heart or one-notrump short a stopper, as partner will seldom compete further without a fifth diamond.

Zia, the master of brevity said, “That’s been my bid for 20 years, and I’m not changing now.”


PROBLEM B: Double. Again, a runaway majority.

Frank Stewart was the lone 4 !C bidder and also the lone who asked, “Would double be for penalty?” Kleinman responded, “I’m glad also that you asked the meaning of a double. I don’t know. Do “responsive” (why not just call them advancive?) doubles apply against preempts raised below game? BWS doesn’t specify, but everyone seems to think they do . . . .”

But there were lots of doublers, both on the panel and the IAC. Only a couple of the panelists used the word “responsive,” leaving the name of it somewhat unresolved. But not the intent. As discussed on our forum, it’s a way to convey values, but certainly less than a jump to 4NT would show. It ain’t penalty.

Kokish: “Double. Both strain and level are live issues. Over partner’s three spades, four-clubs (not a torture laden four hearts or four no-trump).” This was my thinking as well.

Plenty of room for additional discussion here. Feel free to weigh in!


PROBLEM C: 1NT. Another majority with 18 panelists choosing 1NT.

Jim Creech, who also chose 1NT said it was “a bit too good in the balancing seat.” Several panelists (who also chose 1NT) agreed. The standard range for a balancing notrump being 11-14.

Bramley, who doubled, stated that it was “worth at least 16 HCP, thus too strong for 1 notrump.” BTW, I ran it through the KnR which said it was worth 18. A bit more than I would have estimated, but still--more than 14. I must say that with all of the 1-notrump bidders who said it was “heavy” or “out of range,” that I’m surprised more of them did not double. They say one thing but bid another.

I did find a kernel of wisdom in Kokish’s description of his 1NT: “If at all reasonable in the passout seat, one notrump is my default.” A reasonable tip to file away for future use.


PROBLEM D: Double. A huge majority. 21 of 28 panelists. Most of the doublers wanted to keep open the “possibility of a juicy penalty.”
My thinking for my 3 !H rebid was, “Shows nine of my cards, rather than just six.” Bramley said, “Shows nine of the card; 3 spades would show only six.” Unfortunately, most of our IAC forum used similar logic.

Bummer!


PROBLEM E: 2NT. Without going into great detail, this was a close vote, with the top two (2 !D a close second) getting 14 and 13 respectively.

I, too, changed my mind at the last moment, initially thinking the “aggressive” 4sF 2 !D was best, but then changing to the invitational 2NT.

Jacobus, for the 2 !D bidders: “In the long run, it pays to bid aggressively when vulnerable at IMPs.”

Bragin countering: “2NT. This eight loser hand doesn’t warrant anything stronger. . . . Partner sees the vulnerability and will strain for game.”

A close choice which resulted in a close result in points awarded: 100 vs. 90.


PROBLEM F: Pass. Finally a classic MSC problem with many, many answers. There were 8 different answers.

With a combination of both offensive and defensive characteristics, this hand could go either direction. The Board-a-Match scoring made this a very close decision. Although the winning vote-getter was Pass, it did not garner a majority, merely a plurality.

Kit Woolsey summarized with, “Pass. We probably don’t have a game, and they probably aren’t going to make. Go for the magic 200.”


PROBLEM G: 3 !S . The majority choice.

The following three panelists summed up the wide range of partner’s hand, but most importantly the possibility that partner’s bidding could include the “very weak” hand.
•   Kit Woolsey: “Three spades. We probably belong in spades. I’m willing to give partner a chance to get out if he has a very weak hand.
•   Kevin Bathurst: “Three spades. Maybe it’s worth four spades, but I’d rather involve partner in the game decision.”
•   David Berkowitz: “Three spades. Partner has a wide range, so I will give him a chance to decide whether to bid game.


PROBLEM H: !H Ten.

Although there were 14 who chose a !D lead, 10 chose the Ace. In differentiating between the !D Q and !D Ace, Kleinman chimed in with, “The only thing crazy is to lead the queen instead of the ace. Nobody who prefers it says why. Not so the multitude of ace-leaders.” 


The summary is close to 20 pages. If you have specific questions about a specific problem, ask.

My main point here is that while I think that the 2 !H, if undiscussed, should be seen as forcing, there are a fair number of people who play it as non-forcing, using an extended version of nmf to handle the forcing case. My preference is that 2 !H forcing, I think the bots play it that way as well. Others play it non-forcing.

I agree, Ken, this (non-forcing weakish) is one possible way to play it. With discussion, I prefer to play it as shown below. But I totally understand the desire for natural; the fewer gadgets, the fewer disasters.

1 !C - 1 !S - 2 !C - 2 !H = weakish and non-forcing. Exactly like the same auction with a 1NT rebid by opener. It is only due to the extra space permitting an artificial 2 !D rebid by responder that allows this treatment.

1 !D - 1 !S - 2 !D - 2 !H does not afford responder the space for an artificial bid, so 2 !H must be forcing.

With a regular partner I would play it this way, but never undiscussed.


[Added] We had the same discussion, about the same auction, previously: 1 !C - 1 !S - 2 !C - 2 !H

Also, the Billy Miller mention of this treatment can be found here. It is a few clicks in. 1 !C - 1 !S - 2 !C - 2 !H

DECEMBER OZ Answers submitted:

Q1: 3C. Risky, but the suit quality should inhibit a penalty-double.
Q2: 5C. Eureka! A fit.
Q3: 2S. That muscular four-card club suit is awfully tempting, but the allure of staying a level lower with 2 Spades in what is—hopefully—a
4-3 “fit” stands out. A Moysian will play fine at the 2-level.
Q4: 2C. I’ll let others complain about the opening bid.
1NT with a stiff, I can live with. A void? No way. I see no rational alternative other than 2 clubs.
Q5: 2N3N. IMPs. Vul. What else?

Questions: Who is the "moderator"?  I am almost totally ignorant of how marks are given.  The only thing that I am aware of is that there is a panel of experts who give their choice. I do not know who they are and whether or not they are representative of world bridge rather than biased towards a USA experts.  What then does the moderator do?  Does the moderator change each week?  I recently become aware of BWS, and tried to use it as reference to some of the problems and then regretted it.  A case in point is problem B.  Is double responsive or not?  For me it is and so that is what I voted for.  From now on I will not delve into BWS for help.  Can I get access to the views without subscribing to the magazine?  I recall that last month Todd took the trouble to relay some of the views to the forum. 

Nevertheless, I believe that participating in MSC will help in my decision making.  A case in point is a lead of A  !D for problem H did not occur to me.  However, I would dearly like to know why the lead of 10  !H gets top marks.   

Attempting to find every answer to every bidding problem within BWS2017 will not end well. No system will have every answer.

This is what Bridge World Standard is according to the website:
Bridge World Standard is the standard system developed by The Bridge World magazine based on the preferred methods of leading American experts. The system is ideal for use by impromptu or casual partnerships and as a basis for discussion by those who wish to formulate their own system. It is also used as a framework for problems in the magazine's monthly Master Solvers' Club contest.

So is the system "biased toward USA experts"? I don't even know what that means. Since it is a USA publication, and since the panelists are from North America (both U.S. and Canada), then it has an American bent to it I suppose. But most of the problems are quite simply a test of bridge logic, the system being immaterial. More importantly the nationality of the panelists (there are usually 28) being at best a side note. Bridge logic is the same, regardless of geography or national origin.

Once in a while they'll give us a BWS system specific question. Most of the time, in doing so, they provide us with an asterisked explanation below the problem. That's all you need to give it your best guess.

The contest is the longest running contest of its kind, having been running continuously for almost a century. That's a pretty impressive run!

There is a six-director rotation; Bart Bramley and Danny Kleinman are the two permanent directors. The other four are "visiting" directors who are asked to sit in for a month or two. The MSC answers, published in The Bridge World, are a huge task. They are usually around 15 pages of commentary gathered from the panelists.

As far as "how the marks are given," there is an explanation on the website.

Jack, I will message you privately about "gaining access to the views without subscribing to the magazine."

Anyway, my point is that it is always nice to get a good score, thanks again but, for me, that's not the principal attraction. I like hearing what others think about interesting problems.

I agree, Ken. I most enjoy taking the time to think through what are obviously difficult problems, coming up with my own rationale, and discussing it with others. Then comparing my (our) rationale with the panel. It helps to crystallize my own thought process, with the intention that I'll be able to remember and implement it in the future. Even if I do not change my view about an action, the depth of analysis required hopefully stretches my abilities.

Case in point, Problem D this month. I went for the "bid what you see" 3 !H . It is absolutely what I would bid at the table. But the overwhelming majority chose the double. Why? I want to know. I want to incorporate the panel's thinking with my own so that I, too, will make that choice next time. But I'll have to wait for the panel's summary when I receive the magazine for that.

They were tough on scoring, with the second choice getting 40.

BRUTAL TOUGH on scoring! Lots of second choice 40's. You either get it right or go home.  >:( We'll need to wait until the magazine arrives to find out who the director was, but in the past the most brutal scorer has been Kleinman.

Kicking myself on "D." I could smell the double scoring best.

Pages: 1 ... 33 34 [35] 36 37 ... 51
