Dear Chess Friends! 

Here is the list of websites that will help you to improve in chess:

1) Chess.com is the most popular website devoted to chess where you can not only play chess online, but train and improve many of your chess skills. You can do it yourself using puzzles, exercises, drills and educational videos or hire a coach. However, if speaking about educational videos on chess.com, they are mainly for amateurs.

2) Lichess.org is a simple adless platform to play chess online with some additional features offered for free: puzzles taken from the games played on Lichess and some other simple drills mainly for beginners and intermediate club players.

3) Chessable.com is rapidly growing platform where a chess player can learn from course published by famous chess coaches. You can either watch a video or use a move trainer in case if you are going to learn a certain opening. In my opinion, Chessable is the best place.

4) TheChessWorld.com is a place for chess players desiring to improve. This is where you can watch video courses devoted to different chess aspects and improve a concrete chess skill or several skills. There is also an academy for those who prefer to study chess regularly.

5) Chesstempo.com is maybe the best resource consisting of chess puzzles. This is where you can improve your tactical vision or just practice a certain tactical motif.

6) Database.chessbase.com all games played by rated players in official tournaments are published there. This is where you can learn how GMs play a concrete opening. If you are looking for a novelty, this is probably the best place.
