I perfectly understood your explanation, it's just literally "you are wrong because you are wrong"
"Chess cannot be represented mathematically either, according to someone who is far more qualified in maths than you have a hope of ever being"
except for that it literally already is represented, that claim is made by nobody. you do realize that computer engines use a mathematical representation of chess right?
You know what that translates as?
"you're wrong because you're wrong" means that "I have a friend who says or I read somewhere that it can be solved and I'm just 13 years old and what I say is right!" That's what you're doing. Very, very incorrect.
optimissed you claim that chess cannot be represented mathematically, so where's the proof of it. where's the math journal that contains the proof.
