Concise description:
If you select this option, you will be randomly paired with someone else picking this option in a game neither of you have played
Specifics/Details:
This would be limited to people with at least 20 non-Beta maps never played (or perhaps never won). It would be, in some ways, like a reserved game, except you would not know who you are playing or the map until it starts. (or, if its easier to program, then maybe you would see the players when there are more than 2).
Everyone in the game would be new to that map.
How this will benefit the site and/or other comments:
Offer a way for people to easily find those who have not played a particular map before.
