I think that there are non-physical laws all right: genuine (if not strict) laws written in the language of biology, economics, and so on. But I don't regard that as a contentious issue. Even reductionists about chemistry will think that there are special chemical laws whose formulation makes essential use of chemical terminology.
I'll have spent most of the day before the match doing some preparation. That's a little bit like studying for your exams. You need to know the personalities involved, what the stories are surrounding the game and how they've come into this game. You do a lot of preparation. I like to go in knowing more than I need.
