How do you even play a 960 game on chess.com?
I want only 960 Live challenges

You could make an appointment with others and start a 960 1 day/move game and just play "live".. Got to agree somewhat on a timelimit and just play till mate in 1 hour or so. Play it with someone who is honest and agrees on finishing the game, and not leave in a bad position :)
I would like to play 960 Live Challenges only, how to set it up for ever.
