I would say that after Ke1-g1 with move Rh1-e5 is illegal,
so move would be taken back and I can make a move Ke1-d1.
Of course I should move my king now, if possible.
Other way to think is that I have touched two pieces I am allowed
to touch, so I should 0-0.

That thinking would make captures forced if I touch opponents
piece even before my own. Then I am forced to capture it, because
capture is part of the move.

Other nice trick would be to take own piece out of board,
and not accept to correct it. If opponent now corrects any
piece, then he is forced to capture that too.

Any ot these things should not be in the rules, because we
all should have accepted "the spirit of chess". That's only
rule we need!
