Hi Jock, I'll spout a bit on A, as you've started the discussion there:

A.  3 /3 . Continuations after 1 – 2 : BWS After a strong single minor raise, opener can: (1) show willingness to play in three of his minor by bidding it; (2) bid two notrump natural (but the bidding is forced to three of the minor); or (3) bid a new suit (after which the bidding may still stop at three of the agreed minor).

(1) and (2) are too weak for this hand.  With (3), a common procedure (said the intermediate player of limited experience!) is to bid suits with stops up the line.  If we’re thinking of a 3N contract, we’d like to know if partner has a heart stop.  Without one we’re definitely heading for a diamond contract.  If I rebid 2 , partner may bid 3 (with QJx(x), say) which means I can’t really get him to show his hearts as a 3 bid from me after 3 could be passed by an invite hand.  However, if I skip over spades and bid 3 , partner is forced to show or deny a heart stop.   That seems one route to check hearts if we’re thinking about 3N. 

A re-bid of 3N usually shows 18/19 balanced, which fits the point count, but partner with 11 (his 2 could be GI) and 4c diamonds will pass this --- and we could be missing slam (AQxx, xxx, Qxxx, Kx) or it could be right (Ax, QJx, Qxxx, Qx).  That’s too much of a lottery.

Do we really want to investigate 3N with this hand opposite a partner with 11+ and a 4-card diamond suit?  I’d opt straightaway for a diamond contract.  The only issue being which level.  We’d like to know partner’s controls.  Though splintering with an Ace is frowned on, that will get partner bidding his Aces and Kings, specifically here, showing/denying spade ace.  That will help.  So, let’s try 3 . 

Without the spade ace partner could 3N (showing heart and club stop), which we could pass, or 4 /4 (showing KQ) which we can follow with RKC.  With the spade ace partner will bid 3 .  We can then RKC.

After 3 what would be RKC in clubs (I mean generally, rather than in BW)?  4 as minorwood? 4 as kickback RKC?

Problem A has stymied me from getting started, as I see two basic ways to go after it:  #1 is that we are already headed for diamond slam and only need some way to get to seven if that is "on".  #2 is that we may need to get out at 3 or 4 Notrump, and getting partner's help when that is the case is the more interesting case to study.
  #1 Blackwood will work out if after showing his spade ace, then the club king king(?)  he de   cides  to carry on over "6D" thinking KQxxx in clubs must be a big supply of ready tricks.  If instead he answers 5NT with the HEART king we are stuck with playing 6NT wit exactly 11 known tricks but good hopes for a twelfth.
   #2  involves cue-bidding all 3 of my side features, starting with "2S" (notrump feature, usually).  it might go like this...
            1D                 2D
            2S [stopper] 2NT [BWS2017 says we cannot stop here!?! ]
           3C                3D  [N.F.]
           3H                3S  [spade ace and/or not much help in hearts?]
           3NT [ I think we can legitimately stop here? ]

you hit the  WTF comment  box  pretty well, Todd--thanks!  3 diams on Problem C  is at least as  "out of the box grope"  As the "partner doubles for penalty and  I run away with 3 1/2   quicks, and a suit barely better than what i have shown already"

Help!
  I really need a moderator to enlighten us why on problem G,, partner's double is "negative" or whatever the panel is deciding to call it--rather than "for blood. 
My other 2 or 3 fiascos I can live with, but I
have put 'leaving in pard's double'  IN THE BANK on G

Blu, I don't think I would classify it as "negative." Instead, because we have overcalled at the 3-level, clearly we have a good hand. So the double is merely "card showing," allowing us to bid on (as I chose to do), or convert for penalty. I would expect some sort of 4=2=4=3 or 4=1=5=3 or similar---and about 9-10 HCP?

Very hard month I think!
