Odds game on Chess.com
If you’re playing with a friend who is much stronger or weaker than you, an odds game can make the match more balanced and enjoyable. Here’s how to set it up:
Hover over 'Play' in the left-side menu of any Chess.com page and select 'Play' from the options.
Click 'Custom Challenge.'
Open the Game Type dropdown and choose 'Custom Position/Odds.'
Select your preferred time control and the type of odds you want to use. By default, 'Auto Balance' is selected, which adjusts based on the rating difference.
Enter your opponent’s username and click 'Send Challenge.'
Information to keep in mind
To play an odds game, your opponent must be on your friend list - you cannot play against a random member
