Thanks. Live Game seems to have max 30 minutes time control. How can I keep playing for 1 hour or more (until winner)?
That's 30 minutes per player, making a one-hour game. If you want to play longer than that, add something like 60 second increments. I suspect you may struggle to find opponents with a spare couple of hours available.
If you have no success there, try creating an Open Invite for the shortest possible time. Most people who accept 1/0 games are expecting to make at least a few moves a day.
