Maurice Ashley is a prime example.
By the way, I don't know anything about this guy or whether you are implying he is cheating. He is a black guy playing chess.
I suppose you are saying he gets some sort of special status because he is black? What is that special status? He gets to cheat?
Or, hear me out here, the bias you have requires that black people be at least 30% better than the equivalent white competitor to be considered equal.
This is another form of racism that I have seen. You aren't allowed to just be average to be considered equal.
