I have played about 125 games so far online and am rated 834 in rapid (I did play a lot as a child but not in many years) and I have double the win percentage with white pieces that I do playing as black. Is there any logical reason to this other than some confounding factor I'm not thinking of? I know that white does win slightly more often than black at higher levels and the engine favors white from the outset. However, I think 72% win rate with white and 37% win rate with black is quite drastic. Maybe 125 is too small a sample size and my stats will regress to the mean as I play more, but I actually feel like I'm doing something wrong with black. Almost a feeling of discomfort and constantly responding rather than making plans. Can someone give me some advice on a different way to look at playing with black?
My only theory is that while I don't play with any specifically named openings with either side, I do begin every game along the same lines with white, so maybe I am playing a commonly used opening with white and my opening with black is just not optimal.
