What is Your Reccomendation to d4

I sometimes can be in very bad positions against d4.What is your recommended defence to d4,and what are their basic moves,i will be thankful if you help me.

Nimzo Indian/QID complex

Basically Nf6, e6, Bb4/b6

The Benoni is interesting, and takes a lot of folks out of book very quickly :).

d4 c5

Unless you aren't more specific we can't help you. What type of positions do you think you like? What amount of study time do you have available? etc.

The Slav is generally solid against the Queen's Gambit, but for more general d4 positions, the Tarrasch seems to be an all-round defence.

1...d5, going for the Queen's Gambit Declined. The goal is to get a solid position, equalize, and then see what happens. Very tough defence.

I'd say the main line to go for is 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7 5.e3 0-0 6.Nf3 h6 7.Bh4 b6.

 This is an excellent line to learn and one of the most solid lines for black in the QGD complex. I played it for years as black and it served me well. I would like to add one thing though. I found that many strong players would play 7 Bxf6 instead of retreating the bishop, so you must also be well prepared for this move as well. Karpov and Kasparov both played both sides of the tartakower and you cant get a better recommendation than that imo.

Well, if the King's Indian Defence is too complex for you (and it most probably is), then I recommend you the Dutch Defence. If White plays g3 by move 3, as he usually does in the Dutch (to fianchetto his King's Bishop, thus bringing an extra defender to his King), play the Stonewall Variation, but if he aims for the standard Queen's Gambit setup (pawns on c4, d4 and e3, but most notably the King's Bishop on d3 instead of g2), then I suggest that you play the Leningrad Variation, because the Stonewall could break and you could hang the f-pawn to the Bd3 after you play Nbd7. If you like the Dutch, you could also play it against the English and Reti, and the Anti-Dutch systems won't pose you any serious threats. More on everything here: http://www.fpawn.com/chess/IntroDutch.htm

1.d4 Nf6 2.c4 e5!

Actually, the kingside attack plan in the Leningrad Dutch can be quite similar to the main line KIDs, but the Bg7 is active as well if White tries to castle kingside.

I've been playing the Budapest for a long time, I find it quite solid, and just offbeat enough to catch out a few. Probably not recomended against very strong players, but I know of at least one 2400+ on here who uses it as a main weapon.

Lots of vote chess games in different lines in this group:

I play the semi-slav, it's basicly playing d5 with c6 and e6

I prefer the Slav if possible. Capablanca recommends it in his book A Primer of Chess, with the idea that it does not block Black's light-squared bishop in immediately like the regular QGD does.

Play a little bit of everything.  Just get accustomed to the various types of positions and then eventually pick one you like.

I always loved the semi slav, there's something incredibly harmonious in this line and it's very solid.

1.d4 Nf6

2.c4 g6

3.Nc3 Bg7

4.e4 d6

5.Nf3 O-O for a kings indian defense

d4 Nf6 c4 C5 Benoniii :)

1...d6

if 2 c4  then 2..e5 going into on old Indian type of opening

if 2 e4 then Nf6 going into a Pirc

I am a firm believer in having more than 1 response to 1 e4 and 1 d4. Ofcourse not everyone agrees and some simply dont have the time necessary to learn more than one opening in response to 1 e4 and 1 d4.

 Agreed...the Tarrasch gets a bad rep due to the isolated queen pawn.   But because of that rep, its not nearly as studied as much as other QG lines. 

Eric Schiller has 2 nice books on the Tarrasch.  Gambit Opening Repertoire For Black, and The Ultimate Tarrasch Defense.
