Well, a good aggressive choice is the Leningrad Dutch, but you need to understand the opening a bit. Here is an example of a Dutch line my teacher taught me.
Sharp lines against 1.d4

1. d4 by it's nature is rather positional, so you have to find a balance between sharpness and soundness. A lot depends on whether he plays Queen's gambit (1. d4 d5 2. c4) or any of a number of openings that can spring from 2. Nf3. I love the Englund Gambit, and some of it's relatives, but they can leave you with barely playable positions if white threads his way through the minefield...which is mostly doable with common-sense moves.
If your opponent plays the Queen's Gambit, I would recommend the Von-Hennig Schara gambit as a good sharp alternative.
1. d4 d5 2. c4 e6 3. Nc3 c5 4. cd cd?! 5. Qxd4 Nc6 6. Qd1 ed 7. Qd5 Bd7 (followed generally by ...Nf6, ...Bc5, ...Qe7 and O-O-O. Very active, sharp, and not overplayed.
I also like the Baltic Defense, but that can devolve into a positional battle where black is slightly inferior if white knows what he's doing...but just FYI...
1. d4 d5 2. c4 Bf5 (the goal is to play an orthodox QGD with the bishop on the outside of the pawn chain, perhaps trading off white's light-square bishop [a huge part of his k-side and q-side attack plans] in the process).
If white avoids all the traps, being able to play ....c6 at most points transposes it into one Slav Defense variation or another...but examples of the traps:
3. cd Bxb1 4. Rxb1 Qxd5 5. a3 Nc6 6. Nf3 O-O-O 7. e3 e5!
3. Nc3 e6 4. Qb3 Nc6 threatening Nxd4 and Nb4
3. Nc3 e6. 4. Nf3 Nc6 5. e3 Nb4
3. Qb3 e5!? 4. Qxb7 Nd7 5. Qxd5 Ngf6 is plenty of fun
And of course, silliness like
3. cd Bxb1 4. Qa4+ c6 5. dc Bc2?! 6. cb+ Ba4 7. ba/Q Qb6 (threatening ...Bc6) 8. Bf4? e5 9. Bxe5 Bb4 checkmate...u get the idea.
Hope that helps
The benoni is the bread and butter of tactical openings read into it a bit so you don't get yourself into too much trouble best of luck to ya!

I don't know the main line, but 5. Nxd4 Nxd4 6. e3 seems playable to me.



How about playing 1....d6. That way you give your opponent options of transposing into the pirc/modern with 2.e4... If he is a stubborn queens pawn player and plays 2.c4 play 2...g6 and see where it heads.... worst you have got is KID best, you take him into modern/pirc lines that he may not be comfortable with.

I think I'll play tne benko gambit. It's certainly agressive and black gets the lead in development if white accepts the pawns.
If it's good enough for Kasparov, then It's good enough for me.

I can recomend you Semi-Slav. It's sharp and if you're in trouble there are many drawing lines. I'll cover only sharpest variations.
Let's start with the Botvinnik
Another main line is Meran:
Hi All. I'm playing an OTB tournament on every monday. Last monday I played two rounds (Time control is 45 min. finish) and I managed to win as black, using the sicilian schveshnikov, to a 1900 player (I'm currently 1640) and then I drew as white against the ruy lopez against a 2000+ player in the second game. Next monday I will play as black the round three, and my opponent is a well know positional player. He always start his games with 1.d4. I looked all the options to play against him and still haven't found a good sharp line against it.
I'm an attacking player rather than positional. So what would you recommend as a sharp option against 1.d4?
