Aggressive openings for black


Very few gambits are completely sound for black. Benko/Blumenfeld gambits being among the few arguable exceptions.
For aggressive openings as black:
- against e4: Sicilian Naidorf or the Dragon (the king-side fianchetto fits with the anti-d4 repertoire)
- against d4: King's Indian Defence, Benko, Modern Benoni
I would like to add against d4 the Dutch as it was designed as a counter attacking opening, and as black against e4 The Dragon is good, two knights defense in the italian (unfortunately you get a lot of Ruy games byt playing 2... Nc6) in the two knights, if white plays Ng5 play Bc5 if you can handle the tactics.
