compromise rules

Compromise rules is an Irish term for international rules football — the hybrid sport that combines Gaelic football and Australian rules football into a single game, played in test matches between Ireland and Australia. The name captures exactly what it is: a negotiated middle ground between two very different football codes, with rules drawn from both traditions so each side can compete on roughly even terms. It's a fascinating sporting experiment that generates huge excitement when the international series rolls around, even if the ruleset pleases neither purist completely.
