And I'm only against rule changes because they would take hundreds of years of theory and analysis and just throw them into the trash.
I can appreciate that. While I like the variety of different rules/variants (I spend my time studying variants/history or solving chess puzzles but rarely play actual games), there would be no advanced tactics if the rules changed too much for patterns to be discovered or codified.
Yeah I get that but they are illegal and you claim that they are legal.
