Related to, but I think reasonably distinct from, Is martial arts history on topic?: are questions about specific martial arts matches on-topic?
For example, an SE about chess might reasonably allow a question 'in Kasparov vs Portisch, 1983, why did Kasparov make [x] move?'.
Would questions like 'Why did Muhammad Ali use [x] tactic in his 1974 match with George Foreman?' be on topic? Or would this belong more on the sports site?
