I have 2 to my name which are worth a read for any player serious about the sport.

I like reading the blogs here, but it's hard to find the good ones. By good I don't mean only those blogs with the best analysis, but those that are both interesting and entertaining in some way. For example the blogs of the great GargleBlaster. Milliern is another one that has a unique voice IMO. After all, if I just want educational chess material I can always strap on the ChessBase VR headset I got the other day.
Thanks for any suggestions.
