Well, the FIDE World Chess Championship is starting up at 2:00 ET today. Where can you view it live?
This is by far the best place to view the games live, hands down, and justifies completely my membership. The Leko-Topalov first-round match up is interesting.
If you are looking for a quick fix and do not want to get involved with downloading stuff, then the Chessgames site offers one game live.
3. Chess FM
Promises live coverage starting Friday, September 30.
4. World Chess Network
They promise to offer live coverage. I could not be bothered messing with their interface when I have ICC.
Chess Live and USCF also promise coverage. You apparently can also pay to view them at the official site (ha!) There will also be good news coverage in the local paper (which requires free registration).
