After finishing a game against an opponent, I saw that there was another game in progress, against the same player, that I didn't agree to play. When I went to it, the timer said 23 hours and 59 minutes. This is kind of annoying if I have to forfeit it. I am white. Can I simply delete it before moving a piece?
One more thing: I trashed one and the guy started ANOTHER game with me, this time with white, where he's moved the first piece. Now, just to clarify, surely I don't have to check in and trash every game someone starts with me, right? If I leave it, not having moved a piece, it won't count against me, right?
If you do not want challenges you can also change your settings to prevent people from challenging. You can still challenge others, or create "open invite" games whenever you want.
Just go to "My Settings/ Challenge settings" using the link near the top of the page, and you can customize your games in several ways. If you set your games limit to zero you will not ever get a challenge or rematch unless you initiate it yourself. You can change these settings around whenever you want to.
Just make sure when you have entered your changes that you drop to the bottom of the page and click the update button so your preferences will take affect.
