How do you like this idea for "correspondence bullet"?

I was thinking there's a way we could combine the convenience of online/correspondance chess (lots of games at once, don't have to wait for the other player, don't have to give up the time for a whole game at once) with the fun of traditional time controls.

• Imagine you start playing a 2|0 game. Your timer starts and you make a move, you have 1:57 remaining. You go to school, and forget the game.
• An hour later your opponent opens the game on their phone (I see this model being targeted at phones). They see your move and then their timer starts. They make their move and their clock stops at 1:56.
• After school you see it's your turn and open the game. After you see their move, your timer starts again from 1:57.

And so on.

Now obviously it's going to be a bit unlike a regular Blitz game as you can think about your moves for longer in between turns without eating time, so I'm seeing this as a more casual game where we just accept some players will use engines or spend hours planning each move - just as some players cheat on chess.com. You just don't play people who you suspect are doing this - it's their loss.

I'd be interested in any thoughts on this, I was interested to perhaps develop a test version (I'm a software developer). The emphasis is on casual, fun chess, not obsessing over ratings and cheating - something you'd play on the bus/train. Sort of like chess.com meets DrawSomething?!

it sounds fast
