Commercial show matches.

Personally, I don't mind spending 100 rubles to encourage players to give their all and put on a good show. I'd watch the show and listen to the commentary. I'd even be willing to act as a commentator myself, or just support the players. On SC2TV, there's an option to support the streamer. It's the same here, just in a different format. Moreover, the quality of the game will be higher due to the increased motivation.
