I have many friends I'd like to play live chess against who are tangibly worse at chess than I am. I'd like to be able to give them some sort of handicap to make the games more even. These are just casual, unrated games. Is there any way I can play with uneven times (give them 10 minutes and me 5 minutes) or uneven pieces (play with a missing pawn/knight/rook)? I see that I can set custom times in live chess, but there's no option to give a different amount of time to each player.

I too would like to see something like this put in place... particularly Knight, Rook and Queen odds. It puzzles me why this feature is not currently available.
