Challenge: Longest survival sequence

Create a sequence of moves which must be played with white, and black can play any moves full knowing the sequence. Goal here is
a) Illegal moves end the survival sequence
b) survive the longest before the shortest illegal move / or checkmate.

Good luck!
In this case Bd2 is not possible with

e3 e5 d3 Qh4 Qe2 Qxf2 lasts 3 white moves.
Well, seems like black knowing the rules will play something like e6, Qf6(or Qh4) and Qxf2+. I really doubt white can hold for more than 3 or 4 moves. :)
What about survival sequence against Stockfish Level 8?
It is impossible to create a sequence longer than 3 moves. You have to protect Qxf2+, Bxf2+, Qxd2+, Bxd2+, Nxc2+, and Nd3+. You can't do that in 3 moves. I would play 1.Nf3 2.e3 3.g3.
