Otherwise the place passes to the Continental Championship.
3. 1. 2. For the purpose of deciding the 5 rated players-qualifiers, as well as any replacements, the average from the following lists will be used: rating lists of July 2008 and January 2009 divided by 2. In case of equality two decimals will be taken into consideration. If the numbers are still equal then the number of games from the two periods shall be decisive. That means the player with the greater number of games shall qualify. If the numbers are still equal then the January 2008 list shall be decisive. If the Elo in this list is still the same, the player with the greater number of games in this list will qualify.
3. 1. 3. Players who appear in the inactive list in both July 2008 and January 2009 lists will not be able to qualify as a rated player. If the player is inactive in one list but appears in the other, then the rating that is published shall be taken as the average.
