Initial toiughts.
PROBLEM A: Pass. i have my bids. I don't have anything else to say. If partner wants to punish, I'll take the plus and hope it is enough.
PROBLEM B: Pass. Partner put on the game force, and my primary responsibility was to keep the auction open. Should I bid the clubs? Maybe, but partner needs to clarify the cue. If he wants to take a piece of 3

, I will pass; otherwise I listen.
PROBLEM C: Pass. This should beat the partscore contracts, and may lose to game contracts (which may not always make). I will go for the plus results.
PROBLEM D: 2

, Let's go with the clue and bid one of my minors. 2

is a bit of a lead director, and I can always go back to support spades if it goes 2

back to me.
PROBLEM E: 5

. Partner is asking about my suit, but has no clue about my strength. My problem is the opponent's suit; this should ask for a control.
PROBLEM F: Yes / 5

. What is 4NT? I think it asks for a choice in the minors, so I will choose.
PROBLEM G: 3

. I am not sure whether to over or underbid here. I am the uncertainty of the stiff Q

from a jump shift. I am afraid of two of a minor or 3

being passed out when game is on. I do not want to unilaterally bid 3NT or 4

. I also do not want to manufacture a jump shift into a three-card suit. I think 3

is the slight underbid I will make, and leave my slight overbid of 3NT on the shelf.
PROBLEM H:

7. The majors are in front of me, while the minors behind, so I will try hitting partner's length and go passive.
