If you do a combat withdrawal, the opponent has a chance to advance after you for free, correct? What if they have a lower MV than you?

​I'm not sure that the opponent advances "for free"; I think he's still limited by his MV. If he can't catch you, then you can escape the melee.

Does the Bola (and similar weapons) impose the Hindered penalty when held fast by it? Can a held opponent choose to attack rather than break free?

​I'd say the bola victim was prone, not hindered. We should have clarified. The victim certainly can choose to attack or take some other action rather than escaping.

Are things like drawing a weapon considered an action?

​I'd say no, since "Sheathe weapon, draw other weapon" is listed as an example of a potential action. At worst, I might force a combatant who needs to draw his weapon before attacking to strike in phase two.

If an enemy runs past an adjacent squarer on the way to attack someone else, etc., can you take a free attack?
 

Not a free attack, but I'd certainly allow a combatant who'd declared his intent to swing at one target to change that target if a new one moves into striking range. For example, a thief with 40 MV wants to run past an enemy fighter to reach some other target. Because he's running, his movement is doubled; he'll cover 40 feet in phase one and 40 feet in phase two. If the fighter's side has initiative, and if the first half of the thief's movement puts him in striking range, then the fighter can attack the thief in phase two before the thief completes his movement.

I think the roll under mechanic is only used in the optional rule for concentration (try rolling under Intelligence with 3d6 + damage taken to successfully cast the spell).
