Z steps to 10N 5E and hopes his scimitar will take good advantage of this DEX-less upholstery monstrousity. "I shall cut thee into bolts and sell you as drapes!"
I guess you'll have to roll-out the grapple-fest. Since the rug can out-move me, I think tactics would be: get out of grapple (in a perfect world, win the first opposed check), take 5' step, hope AoO takes it down, or it misses and lets me get hew-y with it.
The exuberant Z-man steps back to 10N 0E and readies an action to attack with his scimiatar if the ant comes into range (using his famous Aardvark maneuver).
Hmm...methinks subtlety is lost on this denizen of the cracks in my driveway. Z-man 5' steps to 10N 10E and tries to split some thorax with his scimitar.
