Of course I would rather score well than score badly but I like this thread for two reasons. First it seems to be getting some participation. Anything that gets participation is good. Second, I see it as an useful stimulus for discussion and learning. I am interested in what the panelists think, but I am also interested in what the participants here think.

I mentioned some (after-)thoughts about C. I'll say a few words about A:

KJ97  /  2  / AKT3  / AK64

1 !D - 1 !H - 1 !S - 1NT - ?

 I would expect partner to bid this way holding xx  / Axxxx  /  xxx  /  Qxx.
He could also, I think, hold Qxx  /  Axxx  /  Qx  /  Qxxx.

With the second hand he would, I assume, raise my 2 !C to 3 !C. Might I regret my weakish 2 !C call? Yes, I suppose so. But might I regret a 3 !C call? Yes, I think I might. 3 !C scores 100, 2 !C scores 80. OK.  I may be wrong but I'll be right someday.

October choices will be posted soon, I am holding a seance later this week. Wine will be served.

ooh, nice scores Todd! AS always, I"m answering the biding problems as if I'm on the table. I give myself no more than a few seconds to answer. Then I like to reconstruct my thinking which helps me to see my biases and methods more clearly. Still, I doubt giving it a full analysis would get me to almost all 100s!

Clearly I need to read more carefully, indeed it is BAM.  I also did not note that the X by E was for TO, but since partner and I both have diamonds and W had a natural NT call I didn't need to look.

My carelessness together with your note that XX did not occur to you supports my general contention that the loss of focus  very often where to look when we ask where we went wrong.


I have been thinking more about the merits of 3D. The casual version of LOTT says that since we have at least nine diamonds we can bid to the 3 level, but I have never cared for that version. The original version was more in line with the name. The number of tricks we can make in diamonds, added to the number of tricks that they can take in clubs is often the same as the number of cards we hold in diamonds plus the number of cards they hold in clubs.  Of course at them time that E made his double W had not yet selected clubs. However, N doubled 1C and then raised our diamonds after the 1NT.  EW are showing strength and so I am not so sure N would bid 2D if he held, say, 4=3=4=2 shape.  Maybe we should play N for either a fifth diamond or, more likely, a stiff club. 4=4=4=1 would make 2D seem right.  Perhaps a stretch, but not unreasonable. If we give him that shape then we have nine diamonds and they have nine clubs, so LOTT says that if they can make exactly 3C then we can, likely, make exactly 3D.

Now LOTT is not right as often is its enthusiasts claim, but it seems to be about right on the average. And we have no objection when LOTT underestimates the trick total. So if LOTT is right, or if LOTT has underestimate the trick total, we might be fine with 3D. LOTT is based on double dummy play, but of course we will be brilliant.

I think I am stretching, maybe stretching quite a bit, but I have been trying to see why 3D is right over the X and this is what I have come up with.

Congrats. Your only non-100 is where you agreed with me on C. Be careful of the company you keep!. But I am not yet convinced 3 !D is wise. Being imps, they probably won't hit it since they don't want to double us into a game contract but still. This seems to be there hand, I'm inclined to let them play it.
Thanks! The scoring, however, was BAM, which I have never played. But it was certainly a strong determining factor in my decision. I was just too afraid of getting hammered. I get the presumed reasoning though. Getting back to my comment upthread, the option that somehow escaped me was redouble. I like that choice best. I don't think it even entered my mind, which is silly.  ;) Because it should have. Sigh.
