IMO learn the Scottish Opening. But you have a lot of options for example the King's Gambit despite it's not played that often anymore. But yeah on low elo you can play everything.
Attacking after 1. e4 e5

The standard, classic, and overall best attacking line for White is the Ruy Lopez: 1. e4 e5 2. Nf3 Nc6 3. Bb5. But be prepared to be immersed in an absolutely huge amount of theory if you decide to go that route. The Center Game and Scotch Opening allow Black to equalize too easily. The King's Gambit is good for tactics but supposedly doesn't give White a long-term advantage.

Scotch opening second. Learning the ruy lopez is daunting and is drawish at the highest levels. The scotch has open play and black has less say in where the game goes.

Huge fan of danish gambit, as well as the Patzer opening (1.e4 e5 2. qh5). Very underrated IMO. Never lost a game OTB with it yet (6 wins 3 draws).

I think it is healthy at lower levels to just try a range of different openings. That said i played the Ruy Lopez for years without trying anything else. Then a bit of Kings Gambit which honestly is not usually very fun to play more than every 20th game. Then I got hooked on the Evans Gambit. Then i Thought I would try the Scotch. Now I am more than happy to throw any one of those out there depending on my mood because i have played hundreds of games with each. Did it help my rating? No. Did I learn anything? Yeah to some degree. I can get an idea of what type of middlegame each of these will give me. Do I know all the main lines cold? No, not at all. I am playing 5/5 blitz to get experience and play rapid sometimes to learn how to make better moves more consistently and to try to play higher quality games. The point is, if you are into having some end all be all opening repertoire, it had better be because you are already good in the middlegames and endings. Focus more on finding good moves and time management. Figure out where the critical moments in a game are. Make choices of moves consciously. Study master games and definitely study YOUR OWN GAMES!!!
Hello,
I'm looking for an attacking opening for White after 1.e4 e5. If you suggest an opening, it would be good if you could attach a game in that opening that shows a few ideas of the opening. Something open and tactical is best, although not too unsound! Thanks for your time.
