An orange indicator means “in live chess” or connected to the live chess server.
Are you and your friend playing on the website or with an app? If by website, then you both should go to “play -> live chess”. If you are official friends on chess.com, you should see your friend listed in the friends tab.
Strange problem here, possibly my misunderstanding of the interface?
I have a friend I'd like to play some online games against. We see each other logged in. Neither of us is currently in a game. His status indicator (the little colored square next to his avatar photo) is green, which I take to mean "available" (as opposed to orange, "not available").
Whenever I go to my friend's home page and hit the challenge button, I am informed "<his name> is currently not in live chess and cannot accept your challenge at this time" or similar. We've tried the same thing with him challenging me.
This is a bit frustrating. We joined chess.com at the same time and played our first games against each other but haven't been able to play since--not for lack of trying. Ideas, anyone? Thanks in advance.
