Case 1: With Madrasi, castling is just a kingmove. With maximummer it's
both a king- and a rookmove. So what is it with Madrasi+Maximummer? In
your position, queenside castling is possible under the madrasi rule,
but if it's also a rookmove according to maximummer, then it's not legal
because the rook is paralysed.

In combination with Haan: If castling is a king-move, then only e1
should be a hole after castling. If castling is both a rook- and a
kingmove, both a1 and e1 (in case of queenside castling) should be holes
after castling. So haan would work differently in combination with
Madrasi than in combination with maximummer.
