Final submission
-------------------
PROBLEM A: Pass
PROBLEM B: 1 Notrump
PROBLEM C: 2 Hearts
PROBLEM D: 2 Notrump
PROBLEM E: 2 Diamonds.  My style is generally to overcall with five or more, then double later.  No good reason to change from that style.
PROBLEM F: 4 Hearts
PROBLEM G: Redouble.  I still like splintering, but is 3 or 4 the splinter.  I'm not selling out short of 5 , so I will show extra strength with redouble, which also is the cheapest game, and await developments.
PROBLEM H: Heart Queen

Changes to initial guesses are indicated with reasoning.  HNY all.

PROBLEM H: Diamond Jack

Don't know,  but it wasn't me.  I may have partially disagreed, but would have respected your right to be wrong-headed.

Problem H:>>  Hang on to your seat, folks!  Opener MUST HAVE 8 running spades (even all nine of them)  and the other 4 or 5  are all aces and king(s).  Hence,  he has the SINGLETON diamond ace.   Leading either QJ10  is liable to let him excape for down one, but underleading the diamond king will at least build us a 2nd setting trick, and may put him down five, if partner has Q9xxx.

I agree, Blu. Diamond Jack.
But I see a different construction. Ten hearts to the AKxxxxxxxx And a bevy of stiff aces! 
No lead can give this away. We have them set. But the J keeps partner's Q in his hand, and when I get in with the Q we are off to the races.
I hope.
