Pandora for chess

what pandora did for radio, this website will do for chess, but it's an online chess community that allows users to make money winning chess games. Premise:

1) during registration, users check boxes that indicates their interests and activities (including chess)

2) before the user starts a match with another user, a 5 second pre-roll ad will be presented to them that has to do with their interests. a post-roll ad will also follow

3) during the game, the background of the webpage is a full page ad tastefully presented, much like pandora's system.

4) after every 10 moves, the background changes into a new ad, but the refreshing shouldn't affect the chess board itself. (Caveat: it isn't likely that the user will click on an ad during the game...)

5) for every game a user wins, he pockets a % of the ad revenue generated from that one match

6) there will be a small membership fee to sign up, but it should be nominal compared to average profits for users

7) after every game the user can claim his cash prize, but before he can get the physical check he must give his opinion on the effectiveness of the ad and how the ad can be made better, thus giving advertisers feedback and suggestions
