What are the best chess blogs? I enjoy reading about chess and there is a number of blogs that I follow. And I do toy with the idea of starting a chess blog myself in a distant and uncertain future. So I want to tap your combined knowledge:


What are the best chess blogs you know?
What makes them so interesting?


(I know this is the kind of subjective question, stackexchange usually doesn't go for, but I think this could be a very worthwhile collection, possibly as community wiki.)
For players under 1800 USCF/FIDE, Dan Heisman's blog is an extremely helpful source. He has lots of information on:


Thought process: how Hope Chess can cause losses
Time Management: how to manage your time in order to be able to think as much as possible when the game gets complicated.
Practical tips for different situations: when you're way ahead, it's a different game; when you're losing, complicate the position to try to get your opponent to make a mistake; when your opponent is in time pressure, don't blitz him, etc.
Correcting misconceptions: player not recapturing because then he would get doubled pawns (safety is a 100, pawn structure is a 1), players loses because he didn't "see" something when in fact he didn't look out for it (thought process), player making a quick move in a critical position (hand-waving), Player playing a quick move because all moves look bad (acquiescing), Player rejecting move based on shallow or superficial analysis (quiescence error) . . . The list goes on, check out his blog!
