The November problems (matchpoints question and imps question). Deadline Oct 20.

Code:
See below (for agreements), East-West vulnerable

S-KQ7 H-4 D-A6432 C-AQJ4
South. West.  North. East
              Pass.  Pass
1D.    2H.    Dbl*.  3H
?	
		
* - negative
Dbl = extras, no clear bid; 3NT = to play
4♥ = very strong spade raise

(A) What do you call at matchpoints?
(B) What do you call at imps?
My initial thought is to double at either scoring, especially imps. At imps, I see no chance that partner will sit if it makes, and if we get only +200 when he sits that wont be too bad. If I pick a game without doublng first, it might not make. If I double and he pulls, well reach game, but more likely to be in the best game than if I had guessed without hearing him call over the double.

For matchpoints, I dont feel nearly as confident.Partner will want to pass at this vulnerability, so 3H X making is possible, and +200 is not as good as bidding and making a game. Im still leaning toward double, maximizing our chances of playing in the correct denomination.

Now with only 2 months left, Im in a 3-way tie for second among panelists at 790. Two solvers are tied for the solver lead at 790, including Len Helfgott, who is not in quite as good shape as the partner with whom he is tied, since lowest 2 months get dropped. Len currently has an 80 dropped and the other has a 90 dropped, so if each were to score 80 or less on the November problems. Len would move to only 870 while his opponent would move to 880. I dont remember what my dropped scores are, but think at least one was quite low, so I better get at least one 100 in the last 2 months.

Not familiar with the scoring rules nor the overall scoring and standards. My inclinatioon here is to eschew the Dbl and bid 4C at IMPs. 4H seems a bit much, as does 4S and a conservative 3S is second choice, Even at matchpoints I'd go for 4C.

This is close between double and 4C. I simply refuse to pass with this good of a hand. Of the two, I prefer double, because sometimes partner will have a fifth spade and be able to bid 3S. I don't really see why I might bid differently at matchpoints versus IMPs, but I could see partner being less willing to sit at IMPs, so that's a good thing. A key point is that partner knows I don't have a balanced 15-17, so my extra values double should show approximately this hand, though perhaps this is a minimum.

Problem set: November 2018
Respondent: Steve White (D4)
--------------------------------------------------------

Problem 1
Steve White: Four clubs. Would prefer to double if I knew partner would pull, but at this vulnerability at matchpoints he will be sorely tempted to sit, and that will too often be wrong, only +200 vs a game, Still tempted to double, since bidding may get us to the wrong game, and sometimes 3H X is best. There's even some danger that 4C gets passed out.

Problem 2
Steve White: Double. Stands out. At imps, partner won't pass on a close choice, so our main downside is only +200 vs a game. On the upside, we're very likely to play in our correct suit (I will raise to game, of course.)

Because they are so generous with awards for the non-favorites, I'm probably out of contention after only 90 on the November set. Double was worth 50; 4C, 40 at either matchpoints or imps. So to win now I better get 100 in December and hope for a poor month for anyone ahead of me. With scoring based on dropping 2 months, I might even be mathematically eliminated already.

Here's the December problem.

Matchpoints, East-West vulnerable
S-AQ862 H-J1092 D-AQ9 C-2
South West North East
1♠ Pass 4♠* 5♣
?

* - preemptive, does not deny a side ace or king


A. What is your call?

B. If (and only if) you chose to pass or double in Part A, it will end the auction. What is your opening lead?
My initial reaction was to pass, but given the matchpoint conditions it seems right to double. If 5C is making, there's a good chance you weren't getting many matchpoints even if you save, and even fewer if you pass. So take the call that gives you a chance for a good score.

As to the lead, that's tougher. My initial thought was the heart J, but that could be very bad if partner happened to have a stiff honor. The spade A has the obvious danger of catching declarer void with the K in dummy. Diamonds is absurd. A trump likely gives declarer nothing he could not do for himself, but will he hook partner's honor if I don't help?

I'm leaning toward double, then heart jack. In second place, double, then a trump?
What do you think about those?

Im not normally keen on leading an ace, even in our bid suit, but here I think it best. I have my opener, nothing more or special except for stiff club. Really dont think bidding is appropriate. Since 4S seems far from cold, I dont double.

I chose Pass, then the heart jack.

My reply:
The five-level belongs to the opponents.
With the vulnerability as stated, some partnerships play that a pass here is forcing. But I think that if partner can't double, we might as well just defend this undoubled, and avoid the possible -550. After all, we've made them guess. Maybe they're wrong.

With opponents vul, I don't see any danger of -550 if I double. Other bad scores, yes.

I'm still leaning toward the fact that we made them guess, and need to make them pay if they guessed wrong, so double.

One especially interesting case , a very unlikely one, is the one where they guessed wrong only if we double. In particular, the case where spades makes 10 tricks and clubs makes 9.
