Against d4...

I have problems to play against d4 as black... with white, as a beginner, I always play e4, and so when I play against e4 as black i play e5 without problems, but when i play against d4 i have a lot of problem, I play with 1... d5  I know the basically of this position but I always end up in defensive and locked positions, so I thought to learn the indian defense, is it a good idea? And if yes, which type of indian? Can someone suggest me how to act in this situations? Of course i don't want to study all the opening, but just give me a small repertoire so to go to a playable middlegame against d4.

Thanks to all

I find that with an increase in ratings, d4 starts to get played more frequently. You could be losing because you are playing higher rated players, instead of losing because you are playing d5.

I always play an Indian Nf6 as black to d4 now and really respect how the games play out.  There are a lot of common themes there, so if you get lost or out of your preparation, you can still continue with good play.  I love the Nimzo as black and really stumble over it as white, so I try to steer towards that when black and try to transpose to Queen's Gambit or a tamer anti-Nimzo position as white.

The main responses you should prepare for are:

2.c4

This is the mainline.  I say go e6 and steer towards Nimzo.  If they play Nf3 instead of Nc3, go Bogo-Indian for the easier theory to start and because you still do the Nimzo bishop move Bb4 with common transpositions possible.

2. Nf3

I say go e6 to start here too.  You have good chance to end up in a Bogo situation or related.

2. Bg5

You need to know the Trompowsky if you are trying the Indians.  Mainline follows up with 2... Ne4 3. Bf4 c5 and so on.

2. Nc3

This is going to likely transpose to Blackmar-Diemer Gambit lines.  I would let it go that way rather than playing a c5 and trying to get into Benoni.

I think this is a very solid starting preparation plan for black to start out with.  All of these are very interrelated and share many of the same goals, so the preparation is about as small as one can expect to get to common tabiya.  You have a lot of opportunity to steer the game into familiar ground.  And yet, you can grow into other more complex positions as your familiarity grows.  It allows you to stay away from Benoni, Grunfeld, Budapest, and other sharp positions that take more preparation.

That's very similar to where my preparation started (except I started meeting e4 with c5).

no it isn't this problem because I always play against 1600 to 1900 elo players on otb and against e4 i go into a normal middlegame, against d4 i lose badly

This is an example, i'm playing with black

Awake77, in your game above, you played Nbd7 and Bd6 making 6...e5 very possible for you. White's opening play I think was a bit too slow here. However, it seems to me you were planning to play ...c5 which made your Bd6 bit of an unproductive move.

Lots of books and theory do say a well-timed and successful ...c5 by black leads to equality. There is less talk about ...e5 since white does not normally allow this-a well-timed and successful ...e5 is much easier for black to play.
