Best way to improve your game?

Yeah, but that was just from reading one book and putting the lessons into practice.   If a 1400 player could gain 150 ratings points from each book he/she read, they'd be a GM after reading just 8 books.   I'd say that's a pretty good sales pitch.   

I, of course, am not really qualified to judge, but I wonder if it would help to consider whether "fit"ness is a yes-or-no thing or a matter of degree. Perhaps IM Silman had it in mind that his book was best suited for someone around 1750. Perhaps, as one gets closer and closer to 1400, the more likely it is that this or that portion of the book will seem to be too difficult, whereas, as one gets closer and closer to 2100, the more likely it is that this or that portion of the book will seem to be old news.

Anyway, no two people are completely alike, so, for any specific individual, perhaps the best course is to use available online information to make a judgment.

I would guess that intelligence plays a big part in it as well.  Maybe a 1450 player with an IQ of 140 would get more out of it than a 1750 player with a 105 IQ.   I tend to absorb things faster than most people and am a quick learner.   Some of the concepts were new to me, but I don't recall any of them being over my head.  

Well, I am about 1500, and had a lot of trouble with my attempt to start the book.

Hello everyone,

I'm a new player here on the site and I had a question as a beginner:

How to manage the time? I find quite hard to think fast about all the options, maybe 10 minutes game is too fast for this? What kind of settings do you recommend? Any tipps to manage the time in the best way?

I'm coming from the game stratego, maybe you know, maybe not, in any case, there you have 15 seconds per move, while in live tournaments, you have 4 seconds plus 15 minutes to think. How is it for chess? For the few games I played, I have 10 minutes globally, I Don't have some bonus seconds each move right?

I played Stratego and Checkers without time clock. I can give tips on 10 minutes game. Play the opening moves quickly. Have an opening repertoire. Don't spend more than 30 seconds on a complex position. Spend not more than 10 seconds on middle game moves. No comments on the Endgame.

Dont learn to manage time. Play longer time controls (15 minutes with 10s increments, 20 minutes, 30 minutes, daily chess etc) to give yourself to think. Thats how you learn. Of course you CAN play 5 minutes blitz or 10 minutes because its fun, but you play will benefit more if you give yourself time to think about the moves.

Thanks all for the priecious advices and tipps!

Also, in stratego I reach the top players quite fast, but my rule was to play only 1-2 games per day to be still focus.

Is it also recommended for chess?
