hmm it didn’t strike me when reading but that paragraph in OP is kinda bad as you say.
> the minimax theorem
a less complicated and more correct reference is Zermelo’s theorem, this is combinatorial game theory not economic (a further complication of reality is that the wiki article is kinda bad, it’s just induction). The theory also explains that in fact some chess moves are better than others in a mathematical sense, because some worsen the position more than others (e.g. Win->Draw vs Win->Win). Though it doesn’t match what Tessa says about vectors with lengths very well.
