Also, a “match” can be a single instance of ping-pong or soccer. For example, “I attended my sister’s soccer match this afternoon.” Only one game was played in that situation. “Competition”, however, can indicate maybe a tournament or series of matches. “Competition” can also be broader, to include more activities, like chess, cheerleading, and more. I hope this helps!

Hi Heidi, Both are correct depending on the situation. If it's a formal contest that is being judged or in which the winner stands to achieve some measurable recognition by being awarded a prize, advancing to another level, acquiring a certain title, then you would use "match." "Competition" would normally be used in a less formal setting, a situation in which two people are merely playing the game to see who wins. Now, these are not hard and fast distinctions to be sure; a competition can be formal and a match can be informal. Again, it all depends on the particular situation.
