Common Mistakes When Using Opponent Synonyms

Calling a friendly rival an enemy

Enemy suggests hatred or war, so it is far too strong for a sports rival or a debate partner you respect.

Using antagonist for a real-life rival

Antagonist belongs mainly to stories and films; in real life, rival, competitor, or counterpart usually fits better.

Mixing up contender and challenger

A challenger tries to take a title from the holder, while a contender is any serious candidate who could win.

Using foe in casual conversation

Foe sounds dramatic and old-fashioned, so it can feel out of place in everyday chat about a friendly match.
