How are you trying to watch? When you are on the website you should see a list of Live games being played in one of the panels and those are usually the highest rated games currently being played.
The app should be similar but when I just checked, there were a number of lower rated games mixed in so I don't know how the sorting is being done.
When I click "live chess" it shows an archive of MY games. That panel that you speak of shows up only if I click "play". I don't want to click "play" and abort just to get to the panel of live high rated games. I could get banned for that behavior. How do I go straight to that panel?
If you are v2 of the site, with the large orange Play button, that doesn't actually start any games. You have to be in Live to view games in Live,
How do I go to the list of current live games of highly rated players, so I can observe the game? Thank you.
