Maybe they should just flip a coin to see who moves first. And then flip a coin to see who moves next. And flip again to see who moves next. And so on. That would surely be very fair, and sometimes a player would get a few moves in a row, so opening theory would be obsolete.
Or perhaps White gets half a move, and then Black gets a full move, and then White gets three quarters of a move, and Black gets half a move, etc.
Personally, I like the idea of the two sides moving simultaneously, as what could be more fair than that?
