Hi, some friends invited me in their team and now it's time for me to build a serious repertoire with white (I play Semi-Slav and Caro-Kann with black with good results). Is there someone experienced with 1.d4 that can help me, please?

You might want to check out Zuker’s posts on the Colle-Zukertort. You can also visit his site here:

A Solid, Attacking Chess Opening for White - Home

Personally I use the Torre Attack; it can be used against any Black set up. One warning though: White's strategy will be based on Black's specific setup. e.g. if Black chooses a Sicilian, French, K-Indian type, etc. White must adapt his strategy accordingly. The same can be said of the Colle-Zukertort.

Against any set up? Even 1.d4 d5 ?

Definitely worth looking up the Colle-Zukertort if you're a Caro-Kann/Slav defender. It's not the kind of opening system I would usually recommend but I don't recommend d4 to begin with.

The Colle-Zukertort is not a great opening, but it won't kill you. As opening choices go however I think it's on par with the Caro-Kann. Playable, sound, solid and as threatening as your neighbour ringing your doorbell and go 'boo' at conversation volume when you open the door. You won't have to expand your comfort zone much; which is good, bad, both and neither.

I have a feeling Zuker will have a few things to say too.. (braces for impact)

What of the Grünfeld reversed? Or the Grünfeld defense proper for that matter? I've always been intrigued by them, but unfortunately never investigated very much. I try to focus my energy on e4 territory and just try to know what I'm doing in my defenses to other first moves.

Yes, I like to play 1.d4, then 2.c4, I've never played Colle-Zukertort or Torre Attack. I play Queen's games since a year, and I like it, but I didn't really take a serious look to the theory, now that the competition is coming I would like to build a repertoire based on 1.d4 2.c4

I like this model game by Polgar. After arriving at the basic Torre set up she played Ne5, Qf3, O-O, centralized the R. Followed by the classic pattern of attack: Qh3, Re3, Qh4 and Rh3.

If you just want to play those two first moves you will have to become familiar with more than can be covered here because Black has literally dozens of good defenses. Even assuming he obliges with 1…d5 you have many possibilities to consider. Good luck.

Ok, I'm a 1 d4, 2 c4 player, so hopefully I can get you started. This is what you'll need to look into and gather a little understanding of:

Chigorin: 1 d4 d5 2 c4 Nc6

Slav: 1 d4 d5 2 c4 c6

Queen's Gambit Accepted: 1 d4 d5 2 c4 dxc4

Queen's Gambit Declined: 1 d4 d5 2 c4 e6

Nimzo Indian / Queen's Indian 1 d4 Nf6 2 c4 e6...3 Nc3 Bb4 is Nimzo, 3 Nf3 enters the Queen's Indian.

King's Indian 1 d4 Nf6 2 c4 g6 3 Nc3 Bg7

Gruenfeld 1 d4 Nf6 2 c4 g6 3 Nc3 d5

Modern Defense 1 d4 d6 2 c4 e5

Dutch Defense 1 d4 f5 2 c4 Nf6

Benoni / Benko 1 d4 Nf6 2 c4 c5

Budapest 1 d4 Nf6 2 c4 e5

Tarrasch 1 d4 d5 2 c4 c5 -OR- 1 d4 d5 2 c4 e6 3 Nc3 c5

Thank you Abba, I already know the Slav and the Budapest Gambit (I don't consider the BG a very good opening, but sometimes I play it for fun).
First I would like to improove my play against the King's Indian, I know that is played at all levels but against it I have no experience.

As regards the Queen's Indian, I've always played "fianchettoing" my light square Bishop, but I saw on a book about d4 repertoire that the author advised to not play the bishop on g2, what do you think about?

After 1.d4 Nf6 2.c4 e6 I play 3.Nf3, so I avoid the Nimzo-Indian, if I'm not wrong, I have no need to prepare myself about this opening.

Well... the Grunfeld... I've never faced an opponent that uses this defense

The Dutch is not so common at high levels but I now that is played at lower levels, I had to play against it a couple of times. I played not 2.c4, but 2.g3, because I saw it in a book, but I know that is not enough and I must have a deeper knowledge about the Dutch!

Then I have to consider the Tarrasch, the Queen's Gambit, Accepted and Declined, against them I usually develop the pieces without knowing if I'm following the theoretical lines or not.

I'm about 1700elo, so I think that is the moment to develop deeply my opening knowledge. Can you advice me, please, wich variations are better to face these "main" defenses?

Yeah, the Budapest is pretty rare, but it's a solid opening. It does have drawish tendencies and is a bit passive, so you probably won't see it much.

There are a lot of good openings against the KID, but it all depends on your style. If you're super aggressive, perhaps the 4-pawn attack. If you're positional, maybe the fianchetto variation. If you want a dynamic/unbalanced game, the classical (and any of the variants that come with that) might be your choice.

Playing for g3 against the Queen's Indian gets you into Catalan-esque positions, so I'd suggest playing for the same thing against the Queen's Gambit Declined.
For example, 1 d4 d5 2 c4 e6 3 Nf3 Nf6 4 g3 Be7 5 Bg2 0-0 6 0-0 dxc4 7 Qc2 a6 8 Qxc4 b5 9 Qc2 Bb7 is the main line.

The classical Tarrasch is a good line: 1 d4 d5 2 c4 e6 3 Nf3 c5 4 cxd5 exd5 5 g3

Against Queen's Gambit Accepted: 1 d4 d5 2 c4 dxc4 3 Nf3 Nf6 4 e3 e6 5 Bxc4 a6 6 Bb3 b5 7 a4 b4 is a good line.
