**2**. FIDE **was using the rule of 350 points** in rating difference **from 1 April 2006 to 1 July 2009**.

**3**. The FIDE Handbook stated the rule as this, ” A difference in rating of more than 350 points shall be counted for rating purposes as though it were a difference of 350 points”.

**4**. The following is a simple example when the rule was used:

– Case 1: Player C is rated 2000 (**weaker**) and his opponent 2420. The rating difference is 420 (2420-2000), more than 350 points.

– Case 2: Player C is rated 2000 (**stronger**) and his opponent 1600. The rating difference is 400 (2000-1600), more than 350 points.

**5**. FIDE calculated Elo results for Player C:

– in Case 1: As though the opponent of Player C was rated 2350.

– in Case 2: As though the opponent of Player C was rated 1650.

**6**. Applying the **FIDE rule of 350 points** was the following:

– If you was rated 2350, and 2 your opponents 1000 each, the FIDE average of your opponents was 2000, but not 1000 as expected.

– If you was rated 2150, and 2 your opponents 2600 each, the FIDE average of your opponents was 2500, but not 2600 as expected.

– If you was stronger (for 350 points and more), your Expected Result for One Game was 0.89.

– If you was weaker (for 350 points and more), your Expected Result for One Game was 0.11.
