(When he says “entirely relative” that signals cultural relativism).
To use your chess example a cultural relativist would hold buckle and thong to the argument that if most people in your chess club habitually play scholars mate and bongcloud then those are the soundest openings, full stop, and that you are objectively right to think that.
Of course chess is a problematic analogy because there are proven known optimums, so tha analogy is biased on the side of objective morality.
