Im pretty new to the scene so i really dont know who is who. If someone give a name i assume it is his Voobly name. Based on the rating, Hasan looks like a great pleyer of the past. He isnt there anymore. Did je het a new account?
Also: a 1200 rated gay who is noob (mee) will never win against a pro (2100+ rating). I guess playing against someone like Hasan had way to much skills difference.
Playing rematches is a great Idea. This really depends on the skills level. If i beat someone without any problem i dont see why we have to do a rematch. If i have the feeling i have a small chance to win in a rematch i really want a rematch.
Hasan helped Slam to reach expert level and also other players in the past. I think that's enough for your information.
