From the developer:
BlitzIn is a program that lets you play chess in the ICC (Internet Chess Club) website. It also lets you watch the chess tournaments that are organized in the site. Once connected, the "list of events" is a fast way to access the features of ICC. The program is free to use, but you need to buy membership to play online.
