Usage
What does opponent mean? An opponent is someone who is against another person, as in a game, exhibition, or controversy. Opponent can also sometimes be used to describe being in opposition, as in Felix saw no opponent reason to change his vote. Example: Our opponent is strong, so don’t do anything reckless during the game.
Synonym Usage
Opponent, competitor, rival refer to persons engaged in a contest. Opponent is the most impersonal, meaning merely one who opposes; perhaps one who continually blocks and frustrates or one who happens to be on the opposite side in a temporary contest: an opponent in a debate. Competitor emphasizes the action in striving against another, or others, for a definite, common goal: competitors in business. Rival has both personal and emotional connotations; it emphasizes the idea that (usually) two persons are struggling to attain the same object: rivals for an office.

Explanation
An opponent is your competition, whether it's a rival hockey team, or the other finalist in the chess tournament. Coaches tell you to never underestimate your opponent. Someone who competes or fights against you is your opponent. If you're arguing that chocolate ice cream is better than vanilla, the vanilla ice cream fan is your opponent. An opponent can also be someone who opposes, like an opponent of gun control laws. The Latin word opponent means setting against, and it was first used in English to describe the person who would begin a certain type of philosophical debate.
