This video shows a helpful resource with many chess database links, as well as one large current chess master database that I found while searching. It’s called KingBase. The database consists of about 1.5 million games over the past 25 years (no short games and now low-ELO games included, so these are all quality games to enjoy and help you learn).
You can download the file and open it in many programs, such as SCID.
It looks like the database is updated regularly, so you can go back periodically and download the updated version. I think 1.5 million master games should keep you busy for a while though. 😉
