REALLY ticked off  that the punt of 1 Spade didn't win  problem B  ,  or that i didn't stay with the field's choice of  2D or 1NT  to win the iac contest..  but at least the right rebid did manage a 50  garnering an honorable mention.   Can't waat for the summary to quote the 2 panelist that did choose the 1 Spade rebid   
   We are not suprized that the bottom of the honor roll  took  720 on this largely no-brainer set!

Jock, I am not surprised that a bid that is counter to BWS did not win the problem, much less garner more support from the panelists.  If 1 !S were 4th suit forcing for one round, then I would be surprised, but when holding 9xx and promising a fourth spade, I would expect nearly every panelist to look elsewhere for a bid.  Nonetheless, panelists have not been reluctant to grouse about a favored bid not being available under the system notes; and that is where I would expect to see laments about not having 1 !S available.

Nothing especially shocking.
But I thought the second choice on the lead problem was weird. Underleading the !C K5? That would never cross my mind. Are we banking on partner to have, specifically, the !C Q?


Todd,  No one should be surprised that the unbid suit would be a popular choice.  And certainly, clubs were the second most chosen suit led.  Once you have decided that clubs is a weak point for declarer, how should you try to exploit that weakness.  I decided that the best way, was to sit with the king behind the hand that implied control, so I looked for a safe lead in another suit.  But bridge is a game of judgment, and other judged differently.  As the second most popular choice was to underlead the club king, it got the points.  I'm not sure it rated a 90, but I suspect the moderator did not want to score the 10/9 lower than 90, and reward the more popular club with the same score.  (The politics of MSC scoring.)

Speaking of the politics of scoring, my issue was with Problem C and the selection of 3 !C as the highest scoring choice.  Essentially, the choice was between a game, game force, or game try.  Being in game was the clear panel choice, so all game tries needed to be relegated to lower scores.  I can also see that a game force is more flexible, giving the partnership room to explore slam, while still ensuring game being bid, but it feels like the moderator is imposing his bias on the scoring.  The panel is composed of experts.  If they were not interested in exploring slam (or possibly an alternative game such as 3NT), then punishing the fast arrivals is wrong.

That doesn't mean I agree with all of the other choices picking up 100's, but at least in the case of the other, there was greater justification for the scoring.

November Results

JCreech led the IAC solvers with 710. Masse24 came in second with 700. And a three-way tie for third (VeredK, BluBayou and YleeXotee) with 680.  All were within spitting distance of The Bridge World Honor Roll, which required a minimum of 720.

NAMEBW-SCORE
JCreech     710   
Masse24     700 
VeredK     680   
BluBayou     680   
YleeXotee     680   
        

Only six participants this month.

SOLUTIONS FOR:
James Creech
Fredericksburg VA 22407
U.S.A.

PROBLEM A: 3 Clubs
PROBLEM B: 2 Diamonds
PROBLEM C: 3 Spades
PROBLEM D: 3 Notrump
PROBLEM E: 2 Diamonds
PROBLEM F: Pass
PROBLEM G: 3 Clubs  The only change.  I hate manufactured reverses and jump shifts, but it is easier to understand the jump shift on three cards, than the 2 NT on a stiff in partner's suit.  Rebids of 1 NT and 2 NT are allowed with singletons in BWS, but the sixth diamond speaks for a suit contract when the suit is not solid.
PROBLEM H: Diamond Jack

Not final, but here goes:

Problem A:  3 !C  fairly "standard" as most pointed out.

Problem B:  2!D  more descriptive and less of a lie than either 1S or 1NT.

Problem C:  3!S  agree with the majority (for a change).

Problem D:  3!D  not with the majority 3NT which might need eight more tricks on top while leaving the three-level free for partner to find another bid.

Problem E:  2!D since you really do need four hearts to bid 2H.

Problem F:  1NT, it's rare that panellists worry about little things like stoppers.

Problem G:  3!C  "normal" game-force.

Problem H:  !S5  shouldn't really be giving anything away and might have some useful side effect.

SOLUTIONS FOR: Jock McQuade 3 Bag End Hobbiton OR 97030 U.S.A.
PROBLEM A: 3 Clubs
PROBLEM B: 1 Spade    This HAS to be a "punt", since if I DID have spades I would have enough strength to be rebidding 2 !S over the expected 1NT rebid and would be doing just that now.   (Self-inflicted 20-score?)
PROBLEM C: 3 Spades
PROBLEM D: 3 Notrump   
PROBLEM E: 2 Hearts
PROBLEM F: Pass
[PROBLEM G: 3 Clubs
PROBLEM H: Diamond Jack
