D4 or E4?

"... For players with very limited experience, I recommend using openings in which the play can be clarified at an early stage, often with a degree of simplification. To accomplish this safely will take a little study, because you will have to get used to playing wiith open lines for both sides' pieces, but you can't eliminate risk entirely in the opening anyway. ... teachers all over the world suggest that inexperienced players begin with 1 e4. ... You will undoubtedly see the reply 1 ... e5 most often when playing at or near a beginner's level, ... After 2 Nf3, 2 ... Nc6 will occur in the bulk of your games. ... I recommend taking up the classical and instructive move 3 Bc4 at an early stage. Then, against 3 ... Bc5, it's thematic to try to establish the ideal centre by 4 c3 and 5 d4; after that, things can get complicated enough that you need to take a look at some theory and learn the basics; ... Of course, you can also play 1 d4 ... A solid and more-or-less universal set-up is 2 Nf3 and 3 Bf4, followed in most cases by 4 e3, 5 Be2 and 6 0-0. I'd rather see my students fight their way through open positions instead; however, if you're not getting out of the opening alive after 1 e4, this method of playing 1 d4 deserves consideration. ... a commonly suggested 'easy' repertoire for White with 1 Nf3 and the King's indian Attack ... doesn't lead to an open game or one with a clear plan for White. Furthermore, it encourages mechanical play. Similarly, teachers sometimes recommend the Colle System ..., which can also be played too automatically, and usually doesn't lead to an open position. For true beginners, the King's Indian Attack and Colle System have the benefit of offering a safe position that nearly guarantees passage to some kind of playable middlegame; they may be a reasonable alternative if other openings are too intimidating. But having gained even a small amount of experience, you really should switch to more open and less automatic play." - IM John Watson in a section of his 2010 book, Mastering the Chess Openings, Volume 4

For someone seeking help with choosing openings, I usually bring up Openings for Amateurs by Pete Tamburro (2014).

I believe that it is possible to see a fair portion of the beginning of Tamburro's book by going to the Mongoose Press site.

Perhaps Bullet6422 would also want to look at Discovering Chess Openings by GM John Emms (2006).

"Each player should choose an opening that attracts him. Some players are looking for a gambit as White, others for Black gambits. Many players that are starting out (or have bad memories) want to avoid mainstream systems, others want dynamic openings, and others want calm positional pathways. It’s all about personal taste and personal need.
For example, if you feel you’re poor at tactics you can choose a quiet positional opening (trying to hide from your weakness and just play chess), or seek more dynamic openings that engender lots of tactics and sacrifices (this might lead to more losses but, over time, will improve your tactical skills and make you stronger)." - IM Jeremy Silman (January 28, 2016)

Wow

I must thank you for your limitless aid. I think I prefer d4, then the spielmann variation against the nimzo. Any thoughts?

Possibly of interest:

First Steps: The Queen's Gambit by Andrew Martin (2016) or

Starting Out: Queen's Gambit Declined by Neil McDonald (2006)

https://web.archive.org/web/20140627005627/http://www.chesscafe.com/text/hansen93.pdf

might serve as a general introduction. We have often seen recommendation of the somewhat older book, Queen's Gambit Declined by Matthew Sadler (2000).

A few years ago, there were a number of books with advice for White:

A Strategic Chess Opening Repertoire for White by IM John Watson (2012),

https://web.archive.org/web/20140627105428/http://www.chesscafe.com/text/hansen161.pdf

http://www.gambitbooks.com/pdfs/A_Strategic_Chess_Opening_Repertoire_for_White.pdf

Playing 1.d4: The Queen's Gambit by Lars Schandorff (2012),

The Kaufman Repertoire for Black & White by GM Larry Kaufman (2012),

https://web.archive.org/web/20140626221508/http://www.chesscafe.com/text/hansen162.pdf

https://www.newinchess.com/media/wysiwyg/product_pdf/955.pdf

A practical repertoire with 1.d4 and 2.c4 Volume 1 by Alexei Kornev,

https://www.newinchess.com/media/wysiwyg/product_pdf/7288.pdf

and A Cunning Chess Opening Repertoire for White by Graham Burgess (2013).

http://www.gambitbooks.com/pdfs/A_Cunning_Chess_Opening_Repertoire_for_White.pdf

I think Watson, Schandorff, Kornev, and Kaufman advocated 1 d4 d5 2 c4 e6 3 Nc3 Nf6 4 cxd5 exd5 5 Bg5, while Burgess advocated 1 d4 d5 2 Nf3 Nf6 3 c4 e6 4 Nc3 Be7 5 Bf4.

If the Catalan is your interest, perhaps the most recent book help is to be found in The Catalan: Move by Move by Neil McDonald

https://www.newinchess.com/media/wysiwyg/product_pdf/7685.pdf

Not sure what the focus is for the 2016 books, The Queen's Gambit by Damian Lemos and First Steps: The Queen's Gambit by Andrew Martin.

Advice for Black can be found in Declining the Queen's Gambit by John Cox (2011).

You guys are absolutely brilliant!

How would you combat the kid or the gruenfeld?

I personally choose to play both.  

c4

Reason being very few people bother to learn a decent defence to it. 

I think such issues were considered by Watson, Schandorff, Kornev, Kaufman, and Burgess.
