d4 for beginners

Are there any good, relatively uncomplicated d4 openings that at good for beginners at all? Something with not too much theory or complicated opening lines that I can use to start getting used to this opening in games?

I'm thinking as white, but also interested in good recommendations for black responses as well...

These days the London system is often recommended to beginners. I am not a big fun, though. In fact I think beginners should stay away from d4 altogether. But I am sure there'll be people who disagree.

London is pretty easy 

Don't play the London. It's not chess it's the epitome of " Passivity" 

Learn Queen's Gambit ,control the centre and be ambitious. Most often you'll see yourself in an dry endgame where you'll have nothing but symmetry while playing the London. Don't do this to yourself. 

Trompowsky attack and Catalan are also good choices. Trompowsky is simple. 

London won't teach you to attack and play creative chess. It's just an autopilot opening.

It's impossible for a solid setup to be aggressive. 

If you take the initiative with an attack, that's by definition aggressive.  Look at any of the lessons on here about the London System (for example, the ones by Simon Williams) and you'll see they focus heavily on how to use it as a basis for attacking, rather than just sitting around waiting for your opponent to do something.

When Magnus Carlsen plays the London, is he forced by the ultimate tippy-top of chess theory to play passively or else?  Maybe, I wouldn't know.  Would that we all had his problems.

It's impossible to start an attack without the right foundations. If someone played the semi slav against me and then proceeded to push their h pawn I would die of laughter.

Since you are a beginner and are relatively new to chess I recommend you do the London System for now. I wouldn't recommend getting started on the Queen's Gambit until you are a 1400+,

But the truth of the matter is, I don't think you should branch off from e4 until 1400+ as you still need to learn the fundamentals, 1100 is just below 1200 and 1200 is like a beginner intermediate, so that means 1100 is a low-level intermediate for a beginner.

I am not trying to put a slight on you my friend, as you can learn any opening you want to(and as a chess community we want you to) but for recommendation purposes I recommend you have less of a repitoire and focus on 1 or 2 openings on e4 or d4 and then branch off when you are 1400+, and at the very least 1350, but nothing before then as it will then become overwhelming, and you can become ineffecient and ineffective with openings(and other parts of your game), if not mastered the fundamentals.

Just take it from people who have failed over and over again(aka me), you are going to need to master the fundamentals, and only then branching out will be a wise idea @ashtondayrider, you'll thank all of us forumers in the end if you do it this way. 

Peace be to you,

I don't know why would any agressive player would even choose to play the London system, instead of Queen's Gambit. London is Passive by nature admit it. You put your Knight on d2 instead of c3. You build a center like Caro cann, but you know what's worse? That you do that with white. I agree a better player would always win. But the real concern is why isn't the player( London system one) isn't ambitious? 

And Magnus plays London for fun, he is ambitious but sorry I don't see him as an agressive player.

I agree that the London System makes it extremely easy to play passively and that for someone who wants to play aggressively as such there are likely better options.  Only brought it up because the OP was asking for "d4 with not much theory" and the London is kind of the definition of that.

You sure this is a forum for beginners? lol

All this talk about specific openings is complete nonsense. A beginner can play anything, the only requirement is to follow opening principles.

London and Kings Indian setup. You can use these 2 d4 openings at pretty much any level.. Also if you want something a little different the Dutch as black may be fun

Some interesting discussion here, thanks! I'll start having a look through these suggestions...

Nobody is forcing you to read or reply to these posts, not even sure what you're doing on this bit of the website considering you have no patience for beginners.

I want to improve beyond beginner so what should I do... Invent my own brand new openings based on the key principles?

d4, d5, c4.
It is boring, boring, BORING

stop, you aren't allowed to murder me in that way

Studying openings will get you almost nothing. If you want to improve, you should study tactics 90% of the time, with a bit of middlegame strategy and endgames thrown in.

That is, if you already know and follow opening principles. If you don't, you should probably start with looking up those.
