"Regular articles from strong GMs?"
Is this free? I doubt it. I prefer chessbomb which is free and it has free computer analysis during the games, and that computer is stronger than grandmasters. Also they frequently have free commentary from a grandmaster.
Lichess analysis of games, besides being free, are excellent, certainly better than what
chess.com makes you pay for.
Every time I convince a
chess.com user to try lichess they are very grateful and they never again pay for anything at
chess.com. Now I can't do that. Big brother, aka
chess.com, is always watching. But there is no censorship at lichess where anyone can advertise
chess.com if they don't mind being laughed at.
