In online chess how many moves are required before a game will affect your rating. For example, if someone resigns or times out after a few moves does your rating change.

3 moves from each player are required.

Thanks for the quick response

I think it's actually 4!

4 moves must be made before u get any points from it!....

4 moves by White will affect ratings.

3 moves is not enough.

 This is the correct answer. Unless u 3 move mate.

Thanks, Evil_Homer we must play sometime.

The times they are a changin'.

Only timeouts are treated this way otherwise everything counts.

In the past a three move mate did not count. Now it does.

In this game a player is mated in two moves. His rating dropped from 1415 to 1410. This was quickly followed by a three move mate win raising his rating to 1424.
