No, not 3 and not 5. :D

Repost, maybe?
Sorry, typo in the url... :-/
Well if it's atomic it's quite easy. If not I don't know.
no castling rights info is provided so i'll say
1. e4 e6 2. Bb5 Ke7 3. Bxd7 c6 4. Be8 Kxe8
there are plenty of ways.
For example:
1. e3 c6 2. Bd3 e6 3. Bc4 d5 4. e4 dxc4
I don't really understand why doesn't that work
Rule number 1 = reach the position
Rule number 2 = do it in 4 moves for each
Rule number 3 = still possible castling
Applies to mine solution.
