What is the best way to research openings and endgames in a browser? Basically, I just want to know if there’s any easy way to use websites to practice endgames and openings by just opening my browser. I keep finding downloads to Windows programs, which is a problem when I play chess on mobile devices. Then there are the options that require to pay, which isn’t really something I could do.
Three options I can think of immediately:
https://chess-endgame-trainer.firebaseapp.com/home is a fantastic chess endgame trainer.
Chessable also lets you create your own courses (for free) which you can then do spaced repetition on.
Listudy is another option.
