Preflop reraising

[Supern]

0.25/0.5 NL, 8 player tables. Hero and Villain both have 100bb stacks.
Hero has TA image. Villain is 20/10/2 and seems to be solid.

Hero have AKo on the button.
Villain in the CO, who raises 10% of his hand total, raises first in to 4*bb.

* How much should we re-raise? 12bb total?

* What do we think is his range of hands if he calls our re-
raise?

* How likely is a CB to work if he calls? Seems unlikely to me.

* If villain opens from seat 5 instead do we still re-raise?

* If villain opens from seat 5 and has a PFR of 7% instead, do we still re-raise?
