My initial thoughts:
Problem A: Dbl "The reopening double stands out; shortness in spades, length in at least two suits, enough strength to convert clubs to diamonds under any set of agreements.
Problem B: 3
Trying for 3 NT seems sensible with partner's club fit - I just hope it is not one of those robot small doubletons. If partner has red suit coverage, then I likely only need two tricks from him.
Problem C: 1 NT The soft values and 4=3=3=3 have me bidding a bit conservatively this round, but willing to accept any invitation. I went with 1 NT because I have cards to be led into, and at the one-level, Panelists do not seem to care much about guaranteeing a stopper. If I had a fifth club or a doubleton diamond, I probably would raise clubs.
Problem D: Pass Partner should have a decent read of my hand (HCPs and clubs), so I will pass the double and hope for a plus.
Problem E: 1
I don't like it, but I think the Panel will open at the one level with this 4-7.
Problem F: 3
I have extras and a fit. The least I can do is give partner a boost. The most is to show strength and suggest the fit, while also keeping the bidding as low as I am able.
Problem G: 3
I think this is the situation where partner is forced to 3
and my bid shows a good suit. I am willing to be in hearts with Kx, but would love to be in 3 NT if partner has a diamond stop and the club ace.
Problem H:
3 With all of my strength in the opponent's suits, I like trying to hit partner. Since he was not gracious enough to tell me which major is his, I have to guess. I have two reasons to try spades first: I have the jack and I have three. The jack may help set up the suit more than the
10, and since I rate to get in more frequently than partner, it provides more "safe" exit cards from my hand than hearts.
