Same here. My Standard rating went from 1788 to 2088. That's probably because standard ratings are not at all representative of one's real level (many NMs and FMs are around 1800).
Sudden increase in Rating

GOD, NOT ANOTHER THREAD shaun
Hey, guys! The rating increases in standard are not in error.
http://www.chess.com/forum/view/livechess/standard-ratings-boost?page=1
This is occuring for every player, so the level of your opponents will not increase. We are doing this because we had a deflation issue with standard ratings (and only the standard). With the increased rating, your score is more accurately reflected when compared with the rest of the site. I don't know about you, but playing a 1750 NM just doesn't make sense to me :D
There were also some very steep climbs because the rating pool was "squished" so the new rating pool should more accurately reflect your skill increases.
If you have any questions about this, feel free to drop us a line:

My rating suddenly increased from 1379 to 1529. What is the reason behind this? I did not play any games, during this period, but still there is a jump in rating.
