Online Chess - no points for win


I think a game needs to be four moves to count toward ratings on this site - it's in a FAQ somewhere.

Yes, three or less moves, and it's considered unrated.
If you win a game in exactly four moves or more, you get rating points.

Thank-you to Metastable, StrategicPlay, madhacker and Hydra for your speedy responses. Now I understand. BE warned I may challenge for a game.

Hi there, I did search the forum but found no answer. I was wondering why when I was 1146 and I played a game against someone 1134, won on time after 3 moves I received no points for this win. I presume a certain number of moves must be made. Is this correct and if so, how many?
Thanks in advance for an explanation.

No rating change on a timeout until three and a half moves or seven ply. Like spitting into the wind when I write this in the forums.
The site help and staff says four moves on a timeout. Resignation on any move affects ratings. http://support.chess.com/Knowledgebase/Article/View/16/0/how-do-ratings-work
