Submitted answers--with a few comments . . .

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

PROBLEM A: 2 Spades
Lead directing (possibly), yet competing for the partscore. I intend to take the push to 4 !D. Double, though, intrigues me--showing four spades and a place to retreat to—obviously diamonds. I’m not totally sure of that, so opt for the crystal clear 2 !S. My second choice is 3 !D.

PROBLEM B: 3 Notrump
I like this gadget. Used properly, in conjunction with picture bids and last train, it makes sorting out extras and slam viability more precise. This one feels like a “what else?” choice to me.

PROBLEM C: 2 Clubs
The least lie. One spade looks interesting, but last month’s “cutesy” bid of a three card major has used up my supply of “cutesy” bids for a while. I’m sure there will be a few panelists who choose one spade, but two clubs should receive more votes, and it’s certainly what I would bid at the table. One Notrump also possible, and is my second choice.

PROBLEM D: 2 Clubs
A binary choice again? A bit strong for 1NT, and the single spade stopper is whispering, “something else—not no trump.” So 2 !C it is.

PROBLEM E: 1 Notrump
A binary choice (although I suppose double is also viable). For me, it’s either 1!S or 1NT. While 1NT immediately limits our hand to a specific range, it fails to tell partner of our holding in the spade suit. One spade has the obvious flaw of a less than robust suit (do I want a !S lead?). 
This was very, very close for me. I wonder if the panel will have similar difficulty?

PROBLEM F: 4 Notrump
4NT. I’d like another King. It’s Matchpoints, so who knows. Pass could be right.
 4 !S in a Moysian is possible, and I’m sure there will be a few panel votes for game a level lower. But a 3-3 “fit,” while not likely, is a possibility. And 3-3 play poorly at the four level.

PROBLEM G: (b6)
My first instinct was the “bid what I have” 1 !D, followed by a descriptive jump to 3NT (long solid diamonds). Were this MPs, a prosaic 2NT open would be fine. But it’s IMPs. I want to find the slam—in whatever strain—if it’s there. The descriptive jump to 3NT will help partner assess our chances. It’s risky: Marilyn nailed it when she commented that it screams for a club lead. Crossing my fingers for some luck. Basically, the upside of this risk outweighs the downside.
I think a couple of the alternatives are interesting:
Opening 1 !D then tossing in a “fake suit” jump shift of 3 !C may steer the opponents away from a club lead. Or not.
A fake jump-shift into a three card major, 1 !D – 1 !H – 2 !S, attempting to right-side 3NT (if partner had a club stop) is also interesting. This is actually my second choice.
Tough problem.

PROBLEM H: Diamond 10
Partner has very little. With the opps playing Reverse Smolen, partner has either one or, very rarely, two hearts. If I lead a heart, I need partner to have the A, K, or T.  Is there a reason to give a rule-of-eleven count on my heart suit by leading the six? No, so I would opt for the deuce.
But today I’m leading something else. I worry the heart lead gives away the suit, so I’m hoping to hit gold with a diamond lead. I choose the ten—beginning the unblock—and hope I am finding partner’s five card minor. The diamond King is also a possibility.
(I hate lead problems!)

9:15 am eastenrn, running!

PROBLEM A: 3C
PROBLEM B: 3N
PROBLEM C: 2C
PROBLEM D: 2C
PROBLEM E: 1S
PROBLEM F: 4N
PROBLEM G: b6
PROBLEM H: h6

To be honest on G I'd opt for b3 answer, but I cheated and looked at evaluator, K&R (AJT K9 AKQJT7 T3) = 21.60, wow! If that's true value of this hand, then I suppose it should be open 2N, but it's something I'd never dare lol

I was glad to see that, on E,  Todd found it a close call as to bidding 1NT or 1 !S. So did I. I see that everyone, or close to everyone, chose 1NT. [Curls also went with 1 !S I now see]

A couple of reasons:
1. My major is spades, not hearts. If the auction does not die out at the one level, we might want to contest their 2 !H contract with 2 !S.
2. Often NT plays better when a lot of the values are in lesser honors, and suit contracts play better when the honors are aces and kings.

But yes, I hardly want a spade lead and perhaps that should settle the issue for 1NT. But I went with 1 !S. We will see what the panel thinks.

I truly thought it a coin flip. Maybe the panel will think differently.

One thought about overcalling 1 !S was that I could later double, if needed, to show both a five-card spade suit as well as the strength to compete further.

We'll know soon.

I really thought someone would double.  It isn't that hard to think of the Txxxx as a four bagger - I used to do that all the time with a former partner - then the shape feels more right for a double.  In my mind, 1NT, 1 !S, and Dbl are the three choices, in that order.  All are reasonable choices, the rest is partnership agreements and personal valuations.

MASSIVE scores on the Honor Roll, here: https://www.bridgeworld.com/indexphp.php?page=/pages/msc/mschonorrollforlastmonth.html

It took a 750 to make the MSC Honor Roll, a huge number.

Nice job Marilyn scoring a 740. No bad guesses!  ;D

PROBLEM A: 3 Clubs                   0
PROBLEM B: 3 Notrump           100
PROBLEM C: 2 Clubs                100
PROBLEM D: 2 Clubs                100
PROBLEM E: 1 Spade                  90
PROBLEM F: 4 Notrump            100
PROBLEM G: (b6)                       70
PROBLEM H: Heart 6                   90
                                               650

I expected E, G, or H might score badly, but they did ok sort of. I did not expect A to score badly.  I did consider the X, scoring 80. Shows spades and diamonds I suppose, but I thought I needed five spades for that. Maybe double, intending to follow with 3 !D to show a not so standard snapdragon. Maybe so.
And I thought 2 !S would be spades without diamond support.  Live and learn.
But 3 !C seemed reasonable enough. To me.  0 panel votes and a score of 0.

Some of the scores were interesting. 

I was shocked that 3 !C on Problem A was a zero, and that result caught nearly all participants.

I was also stunned that on Problem G that 2NT received 100.  I thought the entire panel would view the hand as being too good for that bid, but was prepared for any number of other choices to outscore mine.  I was more prepared for 2NT to get a zero than for 3 !C on Problem A to get a zero.

I will be very interested to see what the reasoning was for the lead problem.  I can understand a mild difference between the two low hearts, but the only reason I can think of for the 2 scoring higher than the 6 is it being deceptive when dummy also has four.  Also the Q received almost no points; the best reason I can think of is the panel expects the declaring side to have the 10 and the lead pickles the suit.

The lead problem: If Rho has three hearts then partner has a stiff. If it's a stiff T, or even worse the stiff K, you do not want to lead the Q.

I get the panel's preference for the !H deuce over the !H six. It would have been my second choice. I assume my reasons were in line with the panel's. But I am perplexed by the scoring for the diamond leads. I thought I was being so clever with my unblock of the !D T, attempting to hit my partner's suit. They scored the !D 4 a 70, but only 10 for the !D 10? Is no once concerned about blocking the suit? Apparently not. Sigh . . .

Good job to Blu, by the way, for understanding this and choosing the winning lead. (Though the chances of this making any difference are almost nil).
