The QGD. Nice and classical. You get a feel for these d4 positions. When you understand that you can experiment with other more dynamical options. For instance I have a 60% winrate against the KID because no one under 2000 actually understands how to play the KID.
Best opening for black against Queens gambit

I was taught the East Indian Game for its versatility and counter play. Can be played against the London System as well to kill two birds with one stone. You can choose between c5 or c6 or d5xc4 depending on whites plan. I also play it against the English.

First of all that's a Grünfeld. And it's one of the most hardest openings in chess. And the two games you gave just proves you had no idea what you were doing but your opponent hung his queen for no reason in both of them.

Both games satarting as a Grunfeld Indian, and turning soon to Slechter Slav.
I agree that they are highly educating, especially the second one:
How to skillfully transform a winning position into a losing one, before the opponent dropping his Queen.
Doesn’t ring a bell but I appreciate the feedback!

I played the Semi-Slav for a long time and it's solid but some lines are sharp. I've been playing the QGD lately and it's reliable as well. But, every chance I get (if white plays 1. e4 2. c4) I play the Budapest simply because the positions are interesting to me. It's a questionable opening at best but I've only played a handful of opponents, relatively, that played book moves for long. And even in the games that followed theory, I usually manage a drawn position - though I may well lose due to my own errors. The games you outright lose with the Budapest, though, you usually get steamrolled

When playing as black, what opening do you recommend in response to Queen's Gambit?
If you're dead set on playing the Queen's Gambit as Black, which I wouldn't recommend, play the QGA. It's Black's best chance and a lot of players in the 1000-1100 range band you're in won't know how to play it. My actual recommendation would be to play an Indian Game, as White scores 55/45 in Indian Games, compared to 60/40 in Queen's Gambit.

indeed. I would say, "there is no best defense". Against any white opening. Only realized principled defensive prowess. And that takes time, gained experience and knowledge through playing. Personally, my Chess Philosophy is/has always been: Hold with Black, Win with White. Always in the Present and in Real-time. Though I have won many games as Black, it wasn't because of the defense I was using. I can say the same when I lost. Honestly, I think many here can relate to what I'm saying.

On defense, develop "good" habits. Equalize first before "fishing" for something (it is indeed going to be a problem for you if you don't what "Equalize" means defensively! 😲) Keep your head on a swivel tactically. Keep your pawn formation tight. Especially your Center (keep at least one pawn there). Play for the Endgame: exchange when you can. Exceptions to these is when you have gotten the Initiative, your opponent outright blunders, or overplays. And always above all stay calm, cool n collected in the midst of a wild melee. Nuff said (for now).👍🏼
I play QGD or the Slav as Black, but you need to play it aggressively. Don't go on 'fishing expeditions', but be aware that two too-passive moves will get you into trouble. The nice thing is that this is true for White as well - dawdle around in a seemingly boring equal position, and suddenly Black has the upper hand.
