Some of these might be a bit eccentric

No doubt a result of your Minnesota upbringing. Heck, you probably even double up on the tater tots in your hot dish.

Now that's eccentric!  ;)

SOLUTIONS FOR:
Todd Holes
Glen Ellyn IL
U.S.A.

PROBLEM A: Pass.              Matchpoints--who knows.
PROBLEM B: 3 Notrump.     I see it as a "two bites at the apple" bid. Is the loss of the preemptive value of 5 !D worth it?
PROBLEM C: 2 Notrump.     I’m not overcalling 3 !H with that suit quality and only five of them. 
PROBLEM D: 1 Notrump.     Coin flip. Came up tails.
PROBLEM E: 2 Spades.       Treating as a GF. Will support !H next.
PROBLEM F: Double | Pass. No guarantee that 4 !S makes, so forcing partner to choose a red suit at the five level is high risk.
PROBLEM G: 3 Diamonds.   Forcing.
PROBLEM H: Club 6.           Leads are tough for me. I also like the !C T.

I think it’s close, but being right on the cusp it’s the least lie. Although only 17 HCP, the KnR on it is 18.3 If it’s a game force (or close enough), then 2 !S is clear . . . at least for me.

If the auction continues 1 !C – (1 !S) – X – (P) – 2 !S – (P) – 3 !C – (P) – 3 !H . . . then 3 !H cannot be passed, since a cue-bid and a rebid of responder’s suit is a game-force.

Kokish, in describing this 2 !S bid in the March 2019 MSC wrote, “Sometimes, overbidding a bit can be justified if it helps to locate the best strain for game.”

The very similar March hand was: !S A762 !H KJ4 !D A7532 !C A

The auction started the same, with the question hinging—like here—on opener’s rebid. The surprising plurality vote was for 3 !H , which left me scratching my head. But the hands are different, the primary disparity as I see it is the stiff !C A in the March hand. That makes the jump to 3 !H there more attractive since ruffs are more likely. Here, that !D Q mucks up the works for any intended ruffs. A flaw, at least as far as a jump to 3 !H .

This month’s hand is a point stronger, making the game-force less distasteful. It’s certainly the best way to discover our best strain. If I squint, I can see it.

2 !S for me.  :)

I've got my mind made up on all but one, PROBLEM E.

Here it is:
!S 965 !H AT6 !D AQ !C AKT86

Auction:
1C - (1 !S) - X - (P)
??

Question: Do you consider this a game-force hand? Or more precisely, close enough to stretch?

2/1 Talk / Impossible 2 Spades . . . Extended
« on: August 31, 2019, 02:22:11 AM »
Your are dealt the following hand:

      !S KJ5 !H QT5 !D KJ862 !C 64

Partner opens 1 !H and you respond with a forcing 1NT, intending to show a 3-card limit-raise over partner’s rebid. But partner rebids 2 !H. Now what? Do you continue your plan to show a 3-card limit-raise by bidding 3 !H ? Or do you revalue and, knowing of the 9 card fit, push to game? I’ve seen it done both ways and have done it myself.

Your initial plan intended to bring partner in on the decision. What has changed? Quite often, I’ve seen responders rebid 3 !H in this auction with invitational values but only two-card support. Which is fine. Lacking a better rebid and knowing partner has 6+ !H make 3 !H a relatively safe rebid. But partner does not know how many !H you have in support. Is it two, or three?

Change your original hand to this:

     !S KJ5 !H QT !D KJ862 !C 764

Assuming the same auction that begins 1 !H – 1NT – 2 !H do you rebid 3 !H showing invitational values? Or possibly 2NT denying !H support, potentially missing a known (to you) 8-card fit?

There is a solution.

Simply expand your definition of an Impossible 2 !S to include this auction. Therefore, when you have the first hand your rebid is 3 !H, showing a 3-card limit-raise--which is what you intended to show in the first place. A rebid of 2 !SImpossible!—denotes the 2-card limit-raise. Partner is now in a much better position to determine how to proceed.

I saw two hands recently that could have made use of this Impossible 2 !S. We all learn it as part of a forcing 1NT structure in 2/1 to show a good raise of opener’s minor suit rebid. This is simply an extension. I learned this years ago in a Billy Miller lesson. Miller suggested that the doubleton !H be Qx or better. You can tack on additional complexity over the 2 !S rebid to ask for and target shape and honor placement.

Definitely requires agreement. But it is simple. A cool gadget.

Sleight of Hand / Re: Awkward hand to bid

Here is a question: Does 1 !D - 1 !H - 3 !C - 4 !C - 4 !H show something like this hand?   

I think the issue of whether  1 !D - 1 !H - 3 !C - 4 !C - 4 !H is a natural passable sequence is of some importance.

Ken, I think it must. Since !H was bid naturally, in this sequence where responder was put under a lot of pressure quickly, any bid of his first bid suit should be natural and passable by default.

Opener has other bids available to make a slam move.

This bidding by the way, which I believe Jack also proposed as possible, is how I see the auction progressing.

I agree, Jack, a tricky hand.

My criteria for a jump-rebid in opener’s suit is maybe a bit different. A strict HCP guideline, for me, is approximately 15-17, which is slightly lower than the 16-18 Standard-American and SAYC point count I first learned. Note each range has an upper limit, rather than just a minimum. Since the jump-rebid of opener’s suit is not forcing it absolutely must have an upper limit.

But I don’t use strictly HCP. Shape is part of the equation. Therefore, with the right hand I will make a jump-rebid with as few as 14 HCP. I recall a forum post about 18 months ago where (if I recall correctly) opener had 14 HCP but also had the requisite shape. Both Ken and I chose the jump-rebid as best, believing that it “valued-up” to a jump.

[ADDED] This is the hand from over a year ago discussed above:  !S Qx !H Qxx !D AKQJxxx !C x
 
Here, I believe the South hand to be too strong for a jump-rebid, which is not forcing. I would jump-shift to 3 !C and force game. The !H support is just too good. A good partner will know this has potential to be somewhat artificial, not necessarily showing 4+ in the !C suit. Yes, even with a “pickup” advanced partner.

Alternatively, rather than the jump-shift, a mildly risky—and non-forcing—rebid of 2 !C is possible. Remember, this does not deny values, it is wide-ranging with an upper range of just below what you would jump-shift with. I think a lot of people, for some reason, get hung up on the “that shows a minimum” range for a new suit. Of course—importantly—it does not. Whatever partner does after this 2 !C, assuming she bids, I would intend to jump to 3 !H to show an absolute max non-forcing hand with three good !H.

The jump-rebid of 3 !D, which is not horrible, would be my third choice.

But as I wrote above, for me it’s worth the jump-shift.

More thoughts later, but I am at work.

Playing 2/1, with responder's hand I force game and bid 2 !H. And I do not consider myself a wild or overly aggressive bidder.

Quite often, on hands like this that may be borderline, the question I ask is, "Would I open this hand in first seat?" If the answer is yes, I force game. I suppose I could construct a hand that I would open in first seat but choose not to make a GF response, but I can't think of one easily.

Pass. Jim nailed it.

[Added] I'm thinking it's more like a !S void and 9 or 10.

Early Guesses:

PROBLEM A:  4 !C

PROBLEM B:  3NT. Partner will not pass with a !D void, so I can eliminate that concern. See my earlier post.

Will I bid on if needed? Yes.

PROBLEM C:  2NT. I’m not overcalling 3 !H with that suit quality and only five of them. 

PROBLEM D:  2 !D. Just enough not to pass. Though not forcing, I like for this to show a tolerance for partner’s suit. Preferably Hx, which is coincidentally what I have. Not sure if this is part of the system. I’ll need to check.

PROBLEM E:  3 !H. Yes, really.
[Added] Second choice, which is still in the running, would be 3 !C. Range is correct, but short a !C. Maybe it's better to lie about minor suit length rather than major suit length? 2 !S was the first thing that entered my mind, a simple, unspecified forcing bid. But then what after partner's forced bid?

PROBLEM F: X. Then Pass. However . . . there’s a lot to be said for simply passing to begin with, keeping the trump split and other suits quiet.

PROBLEM G:  3 !D. Forcing.

PROBLEM H: !C 6. Dummy should be exactly 4=3=1=5 (or very close) with around 16 HCP. Opps have a 4-3 !H fit, so even though partner has five !H, I prefer to hide my King, so will refrain from leading it. Pard has no more than around 6 HCP, so I don’t expect to be able to “set up” his !H. Basically this is a “I don’t know what else” lead.

PROBLEM B:  3NT.

I had to check to see if Gambling 3NT was part of BWS. It is.

Partner will not pass with a !D void, so I can eliminate that concern. Operating under that assumption (that partner has one or more !D ), what is the percentage the suit runs? I'm not a math person, so I leave it to our PhD in math to calculate. My rough estimate: well over 90%.

So for me 3NT. The question still gnawing at me, is the preemptive value of 5 !D better than the slim shot at the "wrong-sided" 3NT?

Can't say I'm jumping up & down about that 1 !C open. But I would do the same.

The entire auction seems quite reasonable. I like the 3 !S call, which under pressure can be HX. !S KQ is plenty.

I await your "tale of woe."

The director for September was Kokish.
 
A few snippets from the panel:

PROBLEM A: A fairly clear vote for 3 !S. Kokish called it a “heavy vote” and a “clear indication of its merit.” He went on to say, “It’s true that a Bridge World Standard advancer must start with three spades to investigate slam in hearts, so, for system adherents, the main choices are to go low via four hearts or three no trump, high via a natural four no trump, or TBD via three spades.”

PROBLEM B: Votes were all over the place, but the “get there fast” 4 !S garnered the most panel votes. The general consensus being to “buy the contract.” Close behind, however, were the slam-seeking 4 !C and 4 !H. Interestingly, there were five panelists (Zia, Wolff, Wirgren, Lawrence, Woolsey) who decided to slow-play the hand with either 2 !S or 3 !S. Another two mentioned the “slow-play” !S bids but chose differently. So, as mentioned—votes were all over the place, for all the reasons we stated . . . plus a few more.
Kokish closed with Janice Seamon Molson’s words: “Four spades. Who knows? We could make seven spades. I hate these hands.”

Indeed. Who knows?

PROBLEM C: 2 !S . This is the problem that shocked me the most. I thought it to be a borderline game-force, but the quick tricks and suit quality pushed it over the edge. Jim’s reasoning echoed my own exactly. Alas, the panel did not agree. The reasons for the admitted “underbid” of 2 !S (the plurality choice) included “Matchpoints” and “eight losers.” There were also quite a few 3 !S bids, concentrating on the suit quality and also mentioning it as “the value bid.”

PROBLEM D: 2 !S . Panel votes were quite evenly split, with the top four scores receiving 7, 8, 6, and 6 respectively. The top three, however, were all slam moves, explaining the scores. Bobby Wolff echoed my (eventual) thinking with the “go low” 4 !H stating, “I won’t attempt to thread the slam needle.” As for which “slam move” to make? Mike Lawrence mentioned the fact that 2 !S “leaves room.” Meckstroth and Molson preferred 3 !C as they “hope to hear 3 !D next so I can bid 3 !S next and search for slam.” Others chose 3 !D. As mentioned, quite evenly split.

Kokish, in validating his choice for the highest score stated, “My inclination on slam-zone hands is to start with my longest or equal-longest side suit. Three diamonds would help us when North has a balanced hand, but it will deprive him of the room to jump to four diamonds with four hearts and diamond shortness. That is enough to make 2 spades or 3 clubs more effective first moves, with 2 spades more attractive, because it leaves room for North to show a good five or six card club suit.”

PROBLEM E: 5NT was the plurality choice. While I considered this, I quickly dismissed it as I thought it to be too ambiguous. The panel disagreed, seeing it as primarily a grand slam try. The 6 !C bid that I chose was widely considered a second suit and a way to find grand if partner has the !C AK. Silver, Wirgren, and Robson collectively stated a version of, “if partner has the AK of clubs, he’ll know what to do.” There was not widespread agreement as to what six of a minor means. Gerstman and Meckstroth bid 6 !D as lead directional, Kehela as a try for the grand. Interestingly, many of panel did not consider the grand, signing off in 6 !H.

Rubens was the only one who chose Pass, stating that 6m would be non-forcing. His follow-up would be to pull a double of 5 !S to 6 !C to invite seven. Kokish explains, “Rubens is confident his pass is forcing, because BWS makes a special provision for unfavorable vulnerability in this type of auction. . . . Pushing the opponents to the five-level and selling out has been widely recognized as a sound strategy when ownership of the deal is not clear from the earlier bidding.” That’s an interesting bifurcation of whether Pass is forcing or not; the vulnerability. I’ll have to look that up.

PROBLEM F: 2NT. An actual majority here, with 15 of the panel choosing 2NT. 

PROBLEM G: Redouble. Not the plurality vote-getter, but second. Still, it scored highest. The redoubler’s plan is to bid a later three or four hearts. The thinking being that it is flexible, showing both spade tolerance and a long heart suit. [A good plan in my opinion]. I believe Ken mentioned something similar.

PROBLEM H: !H Q and !H J scored 100. Only one of our solvers (Isabelle10) chose a !H . Most chose a “safe” !S , as did the majority of the MSC solvers. The reasons for the !H lead (as well as all the others) were as varied as the answers. Kokish summarized with, “Panelists hoping for an Ace [with partner] are thinking impure thoughts. Compared with trying to break up a squeeze, playing for a blocked position in the red suits is not only less complicated but also considerably more likely to be right. The heart-honors leaders rule."

« on: August 16, 2019, 01:26:18 PM »
I don't believe any of the 2 !H responses were intended as a negative free bid. They were simply over-evaluating their hands.

As to where it is mentioned that they are alertable in ACBL. The ACBL ALERT CHART states in the category Responses to One Level Opening Bids: Alert----Non-forcing suit bids by an unpassed hand.
