Is there an online chess site or app that would allow me and a friend to play live games against each other with time odds? I am somewhere around a low Class D player, and my friend is somewhere around a high Class F player. He is consistently losing games against me and I know that what little game I have falls apart under time pressure - so, to even things out a bit, I'd like to be able to play him under time odds. Bonus for a free solution, but very willing to look at subscriber sites/apps. (Extra bonus if it's an app and it works on iOS and Android).
On Lichess there is a button that allows you to give 15 seconds to your opponent. You could use it to just give a bunch of extra minutes to your friend at the start of a game.
On the ICC, you can specify a match request to include two pairs of time controls when you request a match with a specific opponent.
For example, you can enter the command:
match FIZZBANG 30 10 45 20
and you would get a SD 30 d/10 time allowance, while FIZZBANG would be playing at SD 45 d/20.
Hope that helps!
