Hi guys, I'm looking for an opening where I get some activity as black. It must be sound, but I don't mind a longterm weakness if I get good compensation.

I'm more of a tactician so I'm looking for an opening that fits my style.

Against e4 I played the french defense but it doesn't fit my style. I'm trying the 2...Nc6 of the sicilian defense right now, with the plan to play e5 soon. Although it weakens my d-pawn I like that I don't have a spatial disadvantage. I'm having trouble though handling the Rossolimo variation properly.

Against d4 I'm not sure what to play either, I'm actually planning on trying the Grunfeld. My usual defense is the QGD, and it's solid but I can't find a lot of counterplay. Usually I find it difficult to get my white bishop in play.

I hope you guys have some suggestions for me :)

vs e4 c5,

vs d4 f5 if you want to go crazy, otherwise there are some crazy lines in the semi slav

Against 1.e4, 1...e5 or the Sicilian are probably the most active. The Scandinavian can give you active piece play as well, but is not quite as good from a theoretical perspective. The sicilian is the most tactical and is ideal for playing to win as black, but it takes far more work than the other openings.

Against 1.d4 you could try the Albin or Chigorin if you really want active piece play from the start, or even the Tarrasch if you like having an IQP. I am pretty sure you won't equalize with any of these if white is super booked up, but then again, how often does that happen? The modern benoni gives black great piece activity at the cost of structural weaknesses, and the Benko gambit will give you a super solid structure and lots of queenside pressure at the cost of a pawn. If you like to attack the king directly than the KID or Leningrad dutch could be for you, though black's play is often more of a slow build up than a tactical melee from the start. The Gruenfeld is quite good if you like to play against a big pawn center. It is a theoretical minefield though, so make sure you know your stuff. The semi-slav can lead to some of the most wild positions I have ever seen, but it can also be very boring. It depends on how white handles it, and there is a tonne of theory for sure.

There are a lot of choices against 1.d4. Try a few of them out in blitz and see what you think. I would suggest the modern benoni or Leningrad dutch if you want to go relatively light on theory, and if you like theory try out the KID, Gruenfeld, or Semi-Slav. Just be aware that the dutch is the most likely to give you a sharp game against lame stuff like the london and colle systems.

 f5 is that dutch defense?
