Broke 27k this evening
After winning my match against klongi (19k) with a 6-stone handicap, the KGS system adjusted my rank to 27k. My thanks go to klongi for having accepted my adjustment to the handicap (from 5 to 6 stones) and for the challenging game.
My rank has advanced rather quickly over the past few days but I don't feel that much stronger. That may just be self-doubt nagging my psyche since I had been a 30k for a very long time. I was expecting to have to claw my way up to the next rank.
I can only trust that, little by little, I'm doing a better job of creatively coordinating what I've learned to date about tactics and strategy.
One disadvantage of getting a higher rank is that your games do get harder and you get fewer handicap stones.
