Abstruse
Legend
I don't know which Jet Li movie you're talking about off the top of my head, but I do know at least one other example of that trope. It was in an episode of Leverage, when the team is up against a rival team and Elliot (the resident badass bruiser) is up against the bruiser for their team. She takes a fighting stance and Elliot then runs through how the entire fight will go based on the stance she took, so he changes his stance (and thus another fighting style)...and she runs through how the entire fight will go based on that and changes her stance/style...and they go through it like five or six times without ever throwing a punch, just staring at each other from a good fifteen feet away in a hallway.The other trope I'm thinking of is that of a "mind fight" between fighters. This is much less common, but when done well, it's really cool. I can't remember the title, but there's a Jet li movie where the entire fight takes place in the minds of the two duelists, with one surrendering in defeat, just based on their stances and their knowledge of one another's fighting styles.
I don't think there's a mechanic present for either of these two tropes.
