 Yes it is, but it is waaay too complex for a question. Assume that the main question can be solved at a glance... If you look long enough.

xii only one with rook not on a8 =0

One last hint: 15 positions are IDENTICAL in one aspect. Now find the odd one out.

 Again too complex. Keep these two things in mind:

1) Mathematical characteristic

2) 15 positions are IDENTICAL in one aspect

 Yes, this is it! No which one has more moves than the others?

 No...

zankfrappa

Board #12, since that white knight is way up in the corner.

Crazychessplaya

#12 is the same number of moves as #11.

zankfrappa

Board #3 because of all those pawn moves.

I won't guess anymore because sooner or later I would just get it right
without really knowing the answer.

 Yes, this is the correct answer! VII shows the opening position for the French Winawer after 14 moves. All other diagrams show the position after 10 moves.
