I'm not sure but i think the tactics increase also helped my rating to. I'm alsost at the peak i set a week ago (in the prime of the tactics peak) I have also been in the 1400's for nearly a month! my peak is now nearing 1500 it being 1485! So i guess that the groups THE BEGINNERS TEAM and Chess Unlimited also helped my rating as well as my tactics.
I just wanted to thank those teams, also the people Jaller and Komolodin (spell check) thanks for the groups.
PS on may 24th it peaked at 1564!
