I think that’s only a problem if your intent is to become the best player in the world. I just play chess for fun and I don’t really care much if I lose. I don’t care about memorising standard openings.

I’m not very good, but if I wanted to memorise a billion different things, I’d study a language or something. Playing online allows me to play with people who are just about as bad as I am when I have a few minutes to spare.
