You're 1400 rapid? That's pretty good.
You might like Sicilian, specifically: the Chelyabinsk, Novosibirsk, and 10... f5 Sveshnikovs or the Kalashnikov Lowenthal, as they strike in the center early, and Black gets a fun, aggressive game, you might like the Taimanov, which is similar but slightly more reserved while remaining aggressive and very solid.
Alternatively, if you don't even want to touch the Sicilian Defense, you could learn the French, specifically: the Poisoned Pawn Winawer (6... Ne7 7. Qg4), the Classical Winawer (6... Qc7 7. Qg4), or the Armenian Winawer (5. Ba5); the 7... Be7 Boleslavsky Steinitz; and the Burn Classical or the MacCutcheon Classical.
Hello everyone, I'm trying to build my little repertoire, just something against 1.e4 and 1.d4. As white I only play the Scotch and I really like it. I was wondering if there are some openings against 1.e4 and 1.d4 that are similar in style (striking in the center, early development, semi-open/open positions, tactics). Kasparov was a Scotch player so I checked his games with the black pieces, I see he mostly played the Najdorf and the Grunfeld. I like those openings but they are too heavy on theory, especially the Grunfeld, it would take too much time to learn them well. I'm open to all kinds of suggestion, thanks
