Here’s a new way to challenge your opponent for your scheduled game without looking all over to find them. Suppose that you are scheduled to play a game on Chess.com against SirIvanhoe with a time control of G/90+30, white pieces for you. Just type this into the message box on the Chess.com live server at your scheduled time:
/challenge sirivanhoe 90 30 rated white
That’s it! A challenge will be issued to me, even if I’m not online yet! You’ll see if you’ve got it right as it should cause a line describing the challenge to appear right under the Play button with a flashing icon. If I am online at Chess.com (even if not in Live) or if I have alerts for Chess.com enabled on my phone, I’ll even get a real time alert of the challenge! The same works for any player that you challenge.
