K=40 for U18

New K factors for rating calculations kicked in with effect from 1 July 2014.

Below is an extract of section 8.56 of the new rating regulations:

= 40 for a player new to the rating list until he has completed events with at least 30 games.

K = 20 as long as a player's rating remains under 2400.

K = 10 once a player's published rating has reached 2400 and remains at that level subsequently, even if the rating drops below 2400.

K = 40 for all players until their 18th birthday, as long as their rating remains under 2300.

The increased K=40 remains for U18 players even after 30 games are played. FIDE took steps to address the situation where up and coming players had low initial ratings. With the old K=15, too many young players had official ratings that understated the current playing strength. Older players in the 1900-2300 range were also affected as these players suffered heavy ratings deflation when they lose to the significantly under-rated young players. With K=40, improving young players should be able to see their ratings increase faster in line with the increase in their playing strength.

The increased K factor cuts both ways for the U18 player. All would be fine if the young player has a positive W-We. A negative figure will see a correspondingly drastic drop in rating. This often happens in age-group events where most players are under-rated such that an under-rated player can still easily lose rating points even if actual performance is higher than Ro.

The new K factors are welcome. Rating changes will be more dynamic and ratings deflation proceed at a slower rate.
