Chess Opening Essentials (The ideas &Plans Behind All Chess Openings) is a good book. However you would need the 1.e4 one and the 1.d4 one


Thank you all for your advice. I have found this site pretty late but i have learned so much from it and the members here. Thanks so much

I believe that it is possible to see a sample from Fundamental Chess Openings by going to the Gambit Publications site.

Here are some reviews of the Essentials books:

In case anyone only looks at the first review, I should perhaps mention that FM Carsten Hansen seemed to think that the series improved over time. A major objection throughout is to the inclusion of many games without annotation. I have mixed feelings about that. I feel that one generally needs some sample games to understand an opening, but it may not be much help to look at games with no commentary. Potential buyers should probably look at sample pages available at the New in Chess site.

Seirawan's Winning Chess Openings is not as comprehensive as FCO, but it is probably a lot more readable. If I remember correctly, it was written around 1999. Here is a review:

I suppose one might also consider the large section on openings (with lots of sample games) in The Mammoth Book of Chess by Graham Burgess.
