That's alot of games just a piece of advice don't start what you can't manage I've known people who've tried to play 300-600 correspondence games at a time and they couldn't handle it.
When you drop out it's an inconvience for players who accepted and want to finish.
I would like to play 200 games from start to finish. please send challenges. 7-14 day. 960 and openings allowed. unrated and takeback also allowed.
