I had the following situation yesterday, on an Imp vs Imp match:
After my opponent ended maneuvering one his interceptors, it ended its movement close to my firespray, well inside my range 1. After thinking a little, my opponent declares a barrel roll, but to my surprise, he doesn't tries to elude my firing arc, he rolls directly towards me, and gently slides the TIE/In base along the template until both (Firespray - Interceptor) bases TOUCH.
So that's it. He claims no overlapping, only touching. Thus, he could perform the barrel roll since technically he never overlapped my ship at any moment, and we couldn't fire at each other.
At that moment and from the top of my head, I couldn't remember any restriction to that course of action, and since I dind't want to waste more time checking rules I conceded and allowed it, with a caveat of not making it a precedent for future games. Later, I couldn't still find anything that explicitly prohibits using barrell roll to just touch another ship's base.
Your Thoughts? Did I miss something?
-------------------
*EDIT:* I think I just found the answer to my own question on the FAQ, where it states that two ships cannot be considered touching if neither of them overlapped in the round. I probably was too sleepy to see that yesterday. Funny that I always wondered what could be the purpose of that rule. However I'm still interested in seeing if everyone agrees on that interpretation.
