Actually what I said was, I was unusually good at math, not that it was something I really enjoyed. And, actually, my strongest subject was English, not math which is why I became an English major. Even if chess is logic and presupposition, those skills are highly mathematical like music or spatial recognition. The math isn’t always blatant or apparent but there is some math involved. And anyway I was only making a point about a talent in one area not necessarily defining talent in another. All this argument over supposition of preference vs capacity is WAY overthinking what I was saying.
