Chess opening explanatory books

Hi everyone! Looking for some great explanatory chess opening books. Currently I have Mastering the chess openings 1-4. I'm also looking for a great book that it covers 1. g3 Benko opening.

You do have a good book. Have you ever tried working with an opening explorer? Benko opening doesn't have a big literature....

I've worked with opening explorers but they don't have explanatory text which is what I need since I'm still a beginner. I have the Small ECO opening book, ECO 2014 from Chessbase. I'm trying to get reputable chess opening books good for beginners, anyone can stare at chess positions but I want to actually make use with my time!

I see openings for amateurs but when I see chess openings explained I see it was by lev alburt, I see that Sam Collins wrote understanding the chess openings, which one were you referring to?

I will share a shortcut that I wish somene had shared with me.  There is a book, "Pawn Power In Chess", by Hans Kmoch.  In chapter 5, Rook and pawns, IM Kmoch reveals a secret that will save you hours of study.  In my edition of the book it is on pg. 107.  The secret is that in almost all openings the position assumes 1 of 6 characteristic formations/pawn structures.  From page 107 thru pg. 373 Mr. Kmoch gives detailed explanations of how to play both the White and Black sides of those 6 characteristic pawn structures. 

Whatever you do not read the book from pg. 1.  It will confuse and discourage you about reading the most important part of the book which begins on pg. 107 or if you have a different edition Chapter 5, Rook and Pawns.  

Jerry, I have FCO-Fundamental Chess Openings from Van der Sterren (a Gambit book). It's a great one-volume  overview of all the major openings, I really like it and would recommend it without reservation. I doubt though it expands on your MCO.

You got very good recommendations from previous comments. I would advice you also to try to stick to certain openings first - even after losses learn from those mistakes and do that opning after you have that down pretty good. Some chess.com opening videos on particular opening are extremely good. 

This information I'm getting everyone is great! Thank you everybody! I consider myself more of a fan of the game and not really concentrating on becoming a tournament player (although getting a little bit better wouldn't hurt). To Eric's question no it does not necessary have to be a book if you have website recommendations you want to throw in. 

I'm currently reading "Studying Chess Made Easy" and reached the opening chapter where he states to study openings correctly you have to focus on memorization 50% of the time and the other 50% you must spend understand the chess opening. This is really led me to ask for explanatory texts. Again thank you everyone! Chess.com I believe is the best chess website!

I have "Understanding the Chess Openings" by Sam Collins and FCO by van der Sterren. FCO is more detailed but also more verbose. It doesn't flow as easily as Collins book, probably because it's a translation from Dutch. My favorite is Collins book and it's what I go to first to read about & understand an opening.

I just got understanding the chess openings and so far it's great!

I am not really a reader so I find reading chess books boring even if they can help.
