I often hear people talk about how our online ratings are supposed to be inflated versions of our official ratings. Oddly enough, I’ve almost always had an online rating lower than my actual rating, on both my ICC and chess.com accounts (both of which, unfortunately, have been rather inactive in recent years due to school).
For the longest time, I thought, maybe I’m overrated? But at the same time, my rating still steadily increased over time. In fact, for basically the entirety of my chess career and for as long as I’ve had my ICC account, my online rating has been at least a hundred points lower than my actual rating.
Evidently, that disparity, although it incited some teasing from some fellow chess players, did not stop me from actually improving my ability to study and progressing both on and off the board.
So don’t let your online rating, whether it be the blitz ratings or the tactics ratings, either boost your confidence too much or drag you down too much. As long as you work hard, you will improve and you will make it.
