I like 1) and I instafold 5) and 6).
But I really have no clue for 2) - 4).
I think I prefer folding 2) since we will be dominated by bigger FDs often, having only 3 outs left. I havent stoved the hands and the 3handed pot with a small and a big stack makes it even more complicated.

If the hands would hit me unprepared in a session, I propably would push 3) and 4) 50% and fold the other 50%, depending on earlyer hands or reads of the MPs.

Sorry bout the blabla-reply ... really hard hands. Good post.

EDIT: wufwugy, would you mind if I "borrow" these hands for posting them in a german forum?
