I am looking for an American or UK folk saying or proverb that reflects the following idea:
- the closer are the players, the higher is the competition or
- the more level the playing field, the more intense the competition or
- the more homogeneous the group, the greater the rivalries ...
I think the general idea is clear, if there is no folk saying the fits it then perhaps a Biblical proverb or some classical (Greek or Roman) maxim would be equally helpful. Or even perhaps some short citation that encapsulates the idea in 1, or 2 or 3.
