I play mostly on ICC, in the 45 45 pool.
In September of 2010, I decided to play chess seriously and simultaneously had an epiphany about how to get better. The results have been very encouraging so far, and I hope they continue to do so. I'm always curious to hear about the experiences of other adult intermediates (or really, non-beginners who just aren't very good) who decide to take on the game in a serious way.
