Nope, nothing weird here, just null move with maybe some conservative and minimal pawn push extensions and some razoring. I find it in 9 plies, but it's +2 until 14 plies, at which point it goes up to +5. If this contradicts anything in my original post on this, it's because I've changed versions and machines (trivial version changes). bruce
