First:  Thanks Todd for copying the problems  (by hand?)  to this department-- saves the casual reader from wondering what we will be talking about.        problem A -  I had a jump rebid penciled in  for two weeks -- tiny stretch.     Then it sunk in  that i was 4th seat, and have hardly any mor that a 4th  "1H" lacking spades should have,   so,  my vote will be simple 2!H rebid.   it still looks like potential magic, though.

B>  2 hearts --  invite+ in spades.  but what to do when partner bids 3S over pass OR opp's 3H?    (70)
C>  3 spades-- i found no reference in BWS  to negative double NOT SHOWING 4 spades,  so       
          jump raise should not be getting us too high in a 4-3 fit. 
         "I like my hand--guess why" cue-bid  not today.                                                                 (80)
D>   lebensohl to 3 clubs, and pass   ( e-1)                                                                                 (90)
E>   3 clubs--natural invitation.   if this isn't that hand  i resign                                                     (100)
F>   pass-- is this so much extras to bid up?    otherwise, what's the problem??                             (100)
G>   pass                                                                                                                                 (100)

Problem H:   !D4   !C2 was my first thought but BWS mentions 'alarm clock' leads to suggest an unusual situation - so I'm thinking 5th highest from 7 diamonds (also unbid suit).  Maybe I am understanding it wrong?

If I were to lead a !D, and I might, I think I would lead the 7.

My intention in leading any !D would be that I am hoping that partner can ruff. If so, then he will realize. perhaps, that my 7 was intended to encourage him to underlead his !H A back to my hand for another ruff. Given that I am holding five spot cards lower than the 7, it is reasonable that he can read the 7 as a high spot.

Now is he void? Or, to put it differently, what can we make of the auction in general and his X in particular?

I would expect North's double of my 5 !H to be mostly based on a couple of small hearts, warning partner off of bidding 5 !S. He can expect 5 !H to go down, but if he passes partner might go on to 5 !S and he has a hand where this doesn't sound so good. But his partner overrules him and bids 5 !S anyway. Surely he has at most one !H.

So: If partner has a !D void and declarer has one !H, then we can beat this by !D ruff, !H back to my K, another !D ruff.

Is that our best bet? Beats me. It's asking a lot.

My thinking right now:

A: 2S
B: 2C
C: 2H
D: 3C
E: 3C
F: Pass
G: 2D
H: D7

As always, I regard the choices as pretty tough.

On A: I think 2 !S is a bit wimpy. But with my stiff !D I like the idea of playing in spades and 3 !S is too aggressive. Maybe I would bid 3 !S with  Axx and a stiff, and decent values,  but not with Jxx.

On B: 2 !C shows clubs and decent values, that's what I have.  If the auction continues I might get a chance to bid 2 !S, I assume such a call would show something like Qx in support.

I will try to post some other thoughts later.

Here are my initial thoughts.

A.   2 !S  Show support and have the right sort of hand for a Moysian fit if partner only has 4
B.   2 !C  Options are not great, but I do have 5 with good values. Places me well if partner rebids !H or cue bids !S
C.   2 !H  Making a general force – willing to treat as a game force – I hope to be in a better position to know where we are headed after partner describes a bit more of their hand.
D.   3 !C I intend to show !H next – I wish I had more HCPs, but with the proper minimum from partner, this could be a slam going, and I am not ashamed to have force game opposite any NT opener.
E.   3 !C As loath as I am to take one of the BWS suggested bids, the suit and values are right for an invitational club bid.
F.   2NT Thought about pass because if partner is going to play in a suit that breaks badly, the extra values and lower level may be best, but partner has taken shown two suits and I have both a stopper and invitational values, so this seems to be my best description
G.   1NT I hate this call the most.  If partner had four spades, there would have probably been a double, so diamonds seem like our most likely fit.  But with only 9 HCPs I am unwilling to pass and hesitant to bid 2 !D.  This seems like it may be the least lie, but I may change my mind and go with 2 !D because it my next closest least lie.  I am trying to decide which least lie is the nearest neighbor to the center of what I consider to be a true reflection of my hand.
H.   !D 7 This feels like a lightener double, so I’m treating it that way.  The 7 is my best spot card to imply a heart entry, so that is the card I am leading.  If I am certain that partner has the CA, would lead it first, and then continue, I would lead the 2 – but I think that would take a mind reader.  Better to try the 2 on the second lead, still suggesting an entry, but one that takes work. If I don't lead a diamond, I think it is a severe breach of partnership trust.

A couple of add-on thoughts about the lead on H:

Regardless of any Lightner meaning (and I agree that it is Lightner-like), partner has to think that there are three tricks somewhere. Surely he is not expecting us to take a bunch of heart tricks so he has tricks elsewhere. Where? Shortness in diamonds seems like a good bet and the auction is reasonably supportive of that. Rho has a lot of spades bur surely at most one heart so there is room in his hand for a few diamonds. Lho has a couple of hearts but not many spades I would think (since he doubled my 5 !H instead of passing or bidding 5 !S)  so there is room in his hand for some diamonds. And I have seven of them. So a !D void seems like a good explanation for partner's double, both on Lightner grounds and on where does he think three tricks are coming from grounds.

One worry I had was that declarer might have no hearts. This is possible. But I only have four. Partner will see the dummy, he can look at his own hand, he can figure I have (at least) four hearts for my 5 !H call, so if declarer is going to ruff the first round of hearts I think partner can figure that out. Hopefully, in that case he has the A of clubs or else two other tricks somewhere. At any rate, after the !D ruff, if declarer has a heart void partner can figure it out and look elsewhere for two more tricks.

Initial thoughts:

PROBLEM A: 3 !H . I see this as a slight variation on The Bridge World Death Hand. Six of my suit, three of partner’s major. Extras. My support for partner’s major, however, is so poor that the space eating 3 !H gets my vote. It’s descriptive of my length. It nails my point range. My second choice would be a flexible 2 !C .
[Added] Now that I think of it, 2 !H (admittedly a super-max) has merit. A distant third fourth choice is 2 !S .

PROBLEM B: 2 !C . Too much to pass. Not enough to force. Raising partner on !S Qx does not interest me.

PROBLEM C: 3 !S . I would not have objected to a downgraded opening of 1NT, but we’re past that. Obviously, I intended to rebid 2NT over any 1-level response. It is a very notrumpy hand. Do I continue with my original plan to rebid 2NT despite the lack of a full heart stopper? I think not. I’m not going to stay wedded to my original plan if the auction steers me in another direction.

What about the spades? Partner’s 1 !S should promise at least five. Do I ignore the “fit”? Although a jump rebid somewhat implies four card support, since partner now promises five, does that still hold?

Another option, and the most flexible, would be to cuebid 2 !H , however, subsequent bids (like delayed spade support to show 3 rather than 4) are game-forcing. Does this hand merit a game force? Is the added flexibility of 2 !H worth the overbid?

PROBLEM D: 3 !C . This one really stumps me. These two-part questions get me every time. First question, how strong am I? 6-5 come alive? Maybe. An immediate 3 !H is pushing it. If I were to bid hearts, I’d go through 2NT first. But an immediate 3 !C , while very pushy, is flexible. It’s forcing and has the added benefit that it may uncover a !H fit, so 3 !C it is. Anyway, that’s my thinking.

PROBLEM E: 3 !C . Systemic. Part of BWS. What else? (Every time I think this I'm wrong.)

PROBLEM F: Pass. I think partner is probably 5-5 for this 2 !D rebid. I’m banking on it with this pass.

PROBLEM G: 2 !D . I could just as easily go with Pass. This is a coin flip for me.

PROBLEM H: !C 2 . Garozzo.

I’ve not pulled the trigger yet. Will probably do so this evening if I have the opportunity to review once more.

Submitted. Stayed with my initial choices above.

E.   3 !C As loath as I am to take one of the BWS suggested bids, the suit and values are right for an invitational club bid.

Funny!  ;D Exactly my thinking.

Every time I read the little notation explaining options below the auction, I get sucked in and bid it. Well, maybe not every time, but every time I do, it turns out poorly.
