I’m sorry if this question has already been asked, but I’m just wondering, what your opinions are about lichess and chess.com? Lichess is a nonprofit and open-source and seems more ethical to me, but chess.com has more features. I’ve been using chess.com for years, but thinking of switching over to lichess or some other application.
Both have/had their issues with cheaters. I personally have a bad experience with chess.com’s costumer support (paid for but didn’t receive the membership). So when I want to play online casually lichess is my first choice. You can use both at the same time and see how they differ when it comes to puzzles, ratings, and all the extra content.
