it's not about books criticism though but using valuable time properly.

If u suffer from some kinda inferiority complex related to chess or ever chess induced, you should watch this remarcable show https://www.youtube.com/watch?v=nwxTuRHlrYM .It features young American masters who are, for some reason, awful players (don't be distracted by the fact that the girls are OK). So if they can do it, then I can do it. Then why don't I put the game away and stop playing. Anyway... watch it, the closest thing to an adult movie that refers to chess!

You are 1600 and already finish endgame course and how to reasses your chess? So you haven't studied them carefully, this is the reason you don't improve.

U r right, Pusher. Or, if we put it in another way, I "studied" them, I didn't use them as training material, didn't build my chess thinking on the foundation of the books, etc., u r right.

I was talking to the OP
