Two From the Home Game

I haven't posted in quite a while, partly because I haven't been playing much so nothing very new has come up. That should be changing over the next couple of months with another NABC right around the corner. A few bridge players braved the cold yesterday to travel out to the Chicago suburbs for the latest edition of the home game. Here are a couple of deals that I found interesting:
The first is a bidding problem. You are fourth in hand vul vs not with:
KJxx
xx
KJ87
KQx
LHO opens 1 Spades and partner bids 2 Spades (Michaels) and RHO passes. What do you do now and what is your plan for the rest of the auction? You can suggest whatever methods you like.

The second is a play problem--

AK2
K84
AKT92
93

986
AQ63
96
AKJ5
you bid to 6 Notrump--something like 1c-1d-1nt-4nt-5h-6nt and get the 7 of hearts lead from West. Suppose you win in hand and run the 9 of diamonds and it holds. What is your plan from here? Alternatively, what if the 9 of diamonds is covered by an honor on your left?
