top ten most instructive chess.com groups

If you had to make a list of the top ten what would it be ?

#1 Dan Heisman Learning center.

Slow games with many different fun types of tournaments, game analysis forum, correspondence matches, Study buddys, and chat club. Also some great prizes!

#2 Aww rats video lessons,

Very instructive FREE videos by an NM (aww-rats) He also hosts simul and does have encourage slow analysis and long games.

I'm not going to rank any more, but there are some blindfold and study groups that can definitely help.

This is just my opinion, feel free to comment.

I look forward to seeing other peoples lists!

Most specific opening groups are a lot of help at times cause you people posting games book refrences etc... on certain lines you may play. Also Vote chess groups who have real discussions during the game is always helpful.
