[Retros] Invisible fairy castling

[Olli Heimo]

Hi friends -
With the initiative of Per Olin, expert in chess960, I composed the following. It should show invisible castling and platzwächsel in very few moves.
nrkrnqbb/p1p1pppp/8/3p4/3P4/8/PPP1PPPP/NRK1NQBB (15+15). Shortest proofgame. I can't computercheck this because in my knowledge Popeye doesn't know chess960 rules, or does it. Olli.
