First: The Number One Free and Open Source Chess Resource—Lichess
If you're a newbie, or starting from ground zero, this where you should start. One would hardly have to go outside Lichess — you can play, analyze, solve puzzles, study, and even watch chess games at Lichess.
OpeningTree.com
Opening Tree is a great resource if you're looking to download games, or research an opponent or favorite player.
OpeningTree.com is an open source website that helps you analyze anyone's lichess or chess.com games. You can use it to prepare for your opponents, improve your own game or learn from openings that grandmasters play.1==Notes==
Note 1: OpeningTree
Open Source Software
I plan to add more to this list of resources, but for now, this is list should serve most beginners quite well.
