Defense against d4

Hello, my name is Brian, I am 14 years old, and started playing chess otb since january, I dont play much chess online , my rating is around 1000. Some older players told me that I should play benoni or benko gambit, I looked at some videos on the internet and looks so complicated, I wonder if those recommendations are sound or not, or what would you recommend?

Nf6 lines are good. kings Indian defence or nimzo-Indian defence. queens Indian defence. or transpose into the queens gambit declined lines. the choice is yours.

Is dutch defense good for my level?

and searching on google, there are three kind of dutchie defense: Classical, leningrade and stonewall

you could try bogo indian, queen indian or mexican defense

Mexican defense looks cool, I like chilaquiles!, my exchange friend from Mexico invites me to eat chilaquiles sometimes.

I also read that there is slav and semi-slav, wow too many to choose from...It feels like going to chinese buffet-

What about queens gambit declined? is it good?

 Moikka Brian.  If you try the Englund Gambit, you may never go back and have loads of fun with this, especially in blitz.  Here are two examples... Don't let 2000 rated players tell you it's no good.  There's an old saying, ANY gambit is sound under 1500.  Enjoy.  

Kiitos!!! 

Here is Englund Gambit Declined.  Nice.  Lots of choices, here is but one.  Go ahead and fork his King and R on move 14 on that one version!  

I hope I didn't mess up anywhere.  Awesome Gambit against d4!  

thanks a lot, I tried it in my last blitz game, the guy abandoned.  Can you tell me how to upload the game here and delete the name of the player, anyway you can check in my stats. thanks a lot for your help. Kiitos paljon!!!

I better show you one more Brian.  Enjoy.

First of all - you should never feel like you have to play a certain opening, or can't play some other opening. If it's got a name and it's in a book or a database somewhere, it's probably a safe bet than you can play it if you really want. All that said, my recommendations would be as follows:

As a new player who is looking to play not just online blitz but also OTB, my first recommendation would be either the queens gambit or the slav. With a rating of 1000 you do not need to learn more than the first few opening moves. Both of these openings will let you contest the center, develop your pieces naturally, castle, and then focus on forming middle game plans. I'm far from a top level player, but I've been playing tournament chess for about 15 years and think this is the most reasonable way for a beginner to start out.

The Nf6 "Indian" defenses are all also good openings and if you want to, you could give them a try. I think they are just a little less intuitive to play than the ones mentioned above, so they don't get recommended to beginners as often.

I love the Dutch and played it for a number of years, but don't really recommend it for a beginner. First of all, because it's a tricky opening that weakens your king from the very first move. Secondly, because you might get good with it over time, but the things you learn it in will be less applicable to non-Dutch games than the strategies you apply in a more conventional opening.

Lots of people on these forums like to promote gambits or off-beat openings. I think that is because the chess.com playerbase is very focused on blitz and fast-paced games. That's not to say you can't play these lines in a slow OTB setting, but that they are less popular there. Giving away a pawn for an attack in blitz is different than giving away a pawn for an attack when your opponent has an hour or more to find the best defensive moves.

In the end it's kind of arbitrary and different people will have different opinions. Just try to find something that will get you to middlegames that look fun to play.

Thanks for all your replies, after reading your comments, watching youtube videos, scanning old books from the local library, I decided that the best option for my level is to use the Queen's gambit declined lasker, it is  relatively easy and intuitive to learn and at the same time  solid  so I can concentrate on tactics and endgames , the Englund gambit however looks good for some blitz and fun games with my school mates.

It might sound strange and it probably is strange but you could reply with 1... d6. I'm quite successfull with this opening, especially because it can transpose into the pirc, a very easy defence, by 2. e4. Also you get to surprise your opponent.

you could try The Slav or the semi-slav
