How should I learn the Queen's Gambit?

How should I go about learning the Queen's Gambit?

The site offers courses and videos on the queen"s gambit.

Should probably just learn opening principles first tbh

I know to Control the Centre, Develop pieces, and castle

As well as to ususally not move a piece twice before you moved the others (sometimes)

TheNightAblaze, if you really want to try the QG as either white or black, then read up a little/watch a intro video about it, learn what the basic ideas are, then play about 50-75 5/0 blitz games of the QGA and QGD, Use the site tools or a openings book to correct opening errors, and, at the end of 50-75 blitz games ,decide if the opening appeals to you at this time.

A real classic.

I agree with all of the above. I add that the Queen's Gambit has been played over and over in many top-level games. Seek them out. The five Karpov-Kasparov World Championship matches have many useful examples although they are now rather old.

IDK what you mean by this. Are you learning this for White? Or Black?

I want to learn to play it AS white

Instead of playing 50 to 75 blitz games to practice, I think it will be more helpful to play through 50 to 75 master games.In addition to the Karpov/Kasparov matches, you can also find excellent examples of this opening in the games of Capablanca, Alekhine, Euwe, and others. While these games are older, the commentaries often provide clear explanations of the ideas in the opening and how the opening transitions to the middlegame. 

only after seeing the master games would I recommend practicing the opening for yourself in blitz games.

That’s good, it is important to establish a repertoire even before you reach 1000 but any serious opening study should be avoided. The ideas in something like the QG are going to be hard to see and implement imo. Plus at that level every other person is going to be trying the Englund gambit on you. I’d worry more about those kinds of opening traps, and try to just stick to openings that have a clear goal that you can understand and work towards then build off that. Just my opinion, but no sense in studying theory that you’re not going to see often. Doing puzzles and just general chess lessons will benefit you 10x. Theres no harm in reviewing master games and opening plans but just don’t spend a lot of time on it yet. Particularly the master games , if you aren’t proficient in tactics you will have no idea why the best players are doing what they are doing. They make those moves because the ideas are not easy to see, and if you don’t have a plan they could very well be dubious, ie sacrificing a piece for no compensation because you don’t know the 5 move follow up.

Studying master games while a low elo player, is akin to studying great English-language literature while just starting ESL, it's largely a waste of time. As the above comments have addressed, low elo players benefit most from drilling tactics until they no longer drop pieces for free to their opponents and can recognize the great majority of one and three-ply tactical opportunities when they appear during games. The overwhelming majority of sub 1000 elo games will leave book after 3 -4 moves, so that's all the theory that's necessary, as well as learning not to fall into a given opening's traps. Above posters are right, learning opening principles ,as well as examples of why its generally a bad idea to violate them, should proceed learning any opening in depth.

In some respects I wholly agree with you, @badger_song but I do want to sort-of make a case for "looking at" (not necessarily depth-studying) top-GM games at low Elo too.

I agree memorising the moves is futile for exactly the reasons you give.

It's unlikely a low Elo player will understand the motivations behind all the moves even with good annotations aimed at being low-Elo-friendly (Keene's books on the K-K matches come to mind as an example of such annotations, Speelman and Tisdall's book on the Moscow World Championship 1984-5 certainly does not).

However, I'd tentatively argue that a 'feel for the shape of the game' (including the resulting middlegames and endgames) can arise by osmosis from playing through such GM games, and to my mind that's laying a useful foundation for understanding when one's Elo progresses; keeping one's positional and tactical improvement fairly even and avoiding one aspect of one's game shooting too far ahead of the other.

I'm definitely not trying to advance a single 'best' approach here. The problem is that every mind is unique and all too often it's a case of "one size fits nobody".

I think you can learn using an app called Chess Opening Preparation and you can also learn from a Channel called Hanging Pawns

indeed. Most players want to learn the QGD as White, although let me tell you it is also beneficial as Black. As a Veteran Player, I like to urge younger players (when building their Opening Repertoire) to also think of Openings as building your Chess Philosophy in general. Not just as White or Black. The Queen's Gambit is One of the Most Fundamental Openings in Chess, learning it, playing it will be tremendously helpful for All of your playing life.

As black just dxc and play the QGA.

Playing the QGD is a great way to learn the difference between positional play, where slow maneuvering will be a feature of a lot of games. That being said, as White, you have to be in the lookout for ideas like the Falkbeer Counter Gambit and the Budapest Defense. At the 3rd move if Black plays Nf6, you might want to avoid 4. cd because Black can take back with the Knight and you have to be ready for a Grunfeld game if 5. e4 is decided upon. Then there's the Englund that a lot of people play. If Black takes on move 2, I like to play 3. e3 the Old Variation because of a trap line that can come available if Black tries to hold the pawn. The opening goes 1. d4 d5 2. c4 dc 3. e3 b5 4. a4 and now if 4... c6 then 5. ab cb 6. Qf3 and Black will at least shed a Knight to save the Rook and guard a7. If White gets too ambitious, though, Black can play to trap the Queen so remembering to keep the Qb3 retreat open is needed. You can even playing b3 if Black tries for holding c4 with Be6 or Ba6. Black gets close to equality in the opening by developing soundly. 3. e4 e5 is a headache but also a great teaching tool for playing the QGA. There's also some attacking games that can be had but for the most part, I think it's one of the better options if you like to play games with a lot of slow moving to improve a position or want to see how pawn structures can determine how the game is to be played.
