For my main openings (the ones I play almost always) I have courses and other sources (such as YouTube videos), but how should I study the openings that I play occasionally (for example, in blitz, to surprise my opponent or against my friends, just for fun)?
Because I don’t think buying a course would be necessary since I wouldn’t even play the openings that much, but what are some other ways to learn the openings I would play occasionally?
Just find in the database the name of a good player who plays the opening you are interested in. Then go over all their games in that opening. If you don't like the way they play it, find a different name and repeat.
