6 6max pf scenarios

[Redd]

This is inspired by a recent pf discussion that I'm not going to link [edit: yet] for fear that it will slant the responses.

You're in a microlimit 6m game, in the BB. It's folded to the guy in the SB, who limps. What's your play if:

1) Villain is 50/1/0.7...
a) ...and you have QTo?
b) ...and you have Q6o?
c) ...and you have Q4o?

2) Villain is 40/15/1.2...
a) ...and you have QTo?
b) ...and you have Q6o?
c) ...and you have Q4o?
