Do bonuses to grappling CMD apply to enemy's rolls to escape grapple?

Question

Human alternate fighter favored class bonus states:

Add +1 to the fighter’s CMD when resisting two combat maneuvers of the character’s choice.

If I want to make one of the choices to be grapple combat maneuver, does the bonus apply

• only when my character is the target, being grappled and on the defensive

• Same as above, but also against the enemy's rolls attempting to escape when my character is the grappler?

Usually any other combat maneuver is completely done after being targeted, but grappling has two participants each making continual rolls and both using CMB and CMD. The confusing part here is the word "Resisting" in the favored class bonus, as that would indicate only when you are being targeted.

Answer 1

This works whenever you're on the defensive, i.e. NOT rolling the dice. So it'll work when someone attempts to grapple you, when someone else attempts to maintain or escape a grapple, or when they try to pin you.

It doesn't apply when you attempt to reverse or escape a grapple.

The bonus will work both for resisting enemy grapples, and to prevent enemies from reversing (or escaping) them. Both of these are grappling combat maneuvers, and any bonus will apply against both unless is specifically says otherwise.
