July guesses:


PROBLEM A: 3NT. Close. My second choice, 3 !D , is too heavy. But the 3NT indicating a solid !D suit is not quite as “solid” as I would like.

PROBLEM B: 3NT. My second choice, a rather esoteric 3 !H, should pigeonhole my shape (two !S ) and willingness to cooperate further or play the 5-2 !S fit.

PROBLEM C: 5 !C. To double then pull partner’s 4 !S to 5 !C to show this hand does not appeal to me. Also, 5 !C (minimally) protects my !D honor.

PROBLEM D: Dbl. What else? [ADDED]: Although I stayed with my first choice, I think 2 !H is very close. It is not too strong for a 2 !H overcall, in my opinion.

PROBLEM E: 3 !D. I am torn on this one (what’s new?). Partner is probably short in !D. Because partner is not flat (see BWS and note on Problem F). I am tempted to try a Walsh type 2 !S , which should deny four !S , but show Hxx and an invite. But how Walshy is BWS?

PROBLEM F: 1NT. A beginnerish call--today I’m a beginner. A race to 1NT—and this will be the explanation by a few of the panel. It’s MP. My second choice is to pass! [ADDED]: The lack of a !S bid from anyone at the table is enough to push me to choose 1NT. This is a "first to 1NT wins" hand.

PROBLEM G: Pass. A possible misfit with partner. Second choice is 2 !D .

PROBLEM H: !H T. Second choice is obviously one of the Aces, but which one? !C A would be a good choice . . . to get a peek at the dummy. Not a tactic I often use. [ADDED] I changed my mind here--going with the !C Ace. I'd lead the !H 10 against 1S-4S, but this preempt auction is different. The !C Ace is less likely to blow a trick directly because any opposing picture cards in clubs are most likely not on my right. The !H 10 might allow a declarer to dump a loser, too. (The !H 10 will be the runaway solver choice.) Admittedly, this is a high variance action.

First guesses. Will look again in a day or so, after some of the IAC cognoscenti chime in! :)

Submitted

A   3N wtp?

B   My very first look up of BWS noting that 1m-2 !S is a Flannery type response.  I have a good 14, so I must either bid game or make a forcing bid.  I also assume that with 1444 partner would open 1  !D.  3  !H must be looking for more info and partner may get the message to bid 4  !S with 6 and 3NT with 5 but I am not taking the chance  I bid 3NT.

C   !C

D   Double

E   Partner is likely to have 6  !C + 4  !S so misfit. I cannot rule out that a Moysian 4  !S might make or 3NT but I am going for the low road.  I bid  1NT

F    1NT

G  !D as all other bids look worse

H Crossed my mind to make an unusual lead like 2 !D, but rejected it.  A passive  10  !H.

A: 3NT. Too good for 3D, but doesn't seem much use in jumping to 3C.
B: 3NT. But what does 2NT mean in this sequence? I don't like the idea of 2NT being a signoff. I asked this on the BBO forums a few months ago and everyone had a different opinion. I liked the last idea of a max with doubleton spade, which this is.. but since I don't expect my partner to know what 2NT means either, I'll just bid the game.
C: 5C - can't see any alternative.
D: Dbl - also can't see any alternative.
E: 1N, but equally torn between about 4 different bids.
F: 1N - if they have 7 tricks, good for them.
G: Pass, though it's quite a gamble.
H: HT like everyone else.

I keep telling myself that I need to stop this procrastination but I never get around to it.

Your Solutions for the July 2019 Contest 
-------------------
PROBLEM A: 3 Notrump

Here I figure I must be missing something. As I see it, this is what 3NT shows and it's what I have.

PROBLEM B: 3 Notrump
I suppose there might be something to be said for 2H. Can partner be 6-4 and bid this way, or would he then bid 2H over the 2D? I decided I don't care, if he is 6-4 it should play fine in spades. And I assume he will not pass 3NT if he is 6-4. I also assume that  if he is 5-4 in the majors then his bid over 2D would have been 2H, so 6-4 is the only issue.

PROBLEM C: 5 Clubs

As has been noted, it's not all that great a bid but I don't see any reasonable alternative


PROBLEM D: Double

If partner bids 3S I will bid 3NT, that should give him a reasonable idea of what I have, and if he bids 4S over my double, not all that likely but possible, I would be tempted to bid 5D.

PROBLEM E: 2 Spades

Todd asked just how Walshy BWS is and the answer is perhaps pretty Walshy but with exceptions.  My thinking is that if pard has a minimum then he will pass and this could well be the right contract. If he has more I would  like it if he allows for other contracts than 4S but is he doesn't, it still could be the right contract.

PROBLEM F: 1 Notrump


This is a very frustrating hand. And it also gets to just how Walshy BWS is. With a dedicated Walshite I might well consider 2C since he will have five clubs to bid this way. But BWS, while saying that pard cannot be 4=4=2=3 doesn't rule out 4=4=1=4. Of course it also does not seem to rule out 2=4=3=4, in which case 2D is right. I assume partner, if 1=4=2=6, will get us out of NT at his turn. And yes, I would like the NT to be played from his side. Among other things, he would have to play it. Maybe 1S is right, I think 1S is some sort of wishy-washy call, not necessarily showing spades and not game forcing. I should look that up.


PROBLEM G: 2 Diamonds

Pard would make a negative double with four spades and a six count so I am not really enthusiastic about leaving this in. I bid a pessimistic 2D.

PROBLEM H: Spade 8

Yes, I know, this might pickle partner's Q, But all leads have issues, I think this is the least likley to help declarer and maybe it cuts down on ruffs. In the old days that 4S call showed five spades but not I think it is often done with four spades and a stiff. If we can hold him to, say, two ruffs we might beat this

Ken, I was chicken to try this. I'm impressed you went out on a limb. Interesting that both 3 !D and 2 !S received a score of 100. I actually like the 2 !S more.
