Best online Opening Explorer?


365chess is okay, although it has some low-quality games. Same with chess.com. I don't think it makes too much difference, though, at least at class level, as long as it has more than a million or so.

Do you know of any better ones? Any downloadable ones, or online?

The chessbase online database is what I use. It is massive and regularly updated.
