The way I remember and interpret the "Kiss the Wall" variant of "Grab and Smash" is this:

*Make an AoA: Double
*Grapple the foe, with two hands, hit location 0 for torso or -3 for head (half face penalty). IIRC it allows using Brawling or any grappling skill
*Smack the foe's face into a wall.
**If you have him by the head, there is no hit location penalty to smack it into the wall.
**If you have him by the torso, use the grappling hit location penalty for the head (-3), because you shove his body but want the face to impact.

So, if you take the penalty on the initial grapple, the smash part gets easier. If you take the easy initial grab, the smash gets harder.
