Tactical openings

Play 1.e4 as White and 1...c5 as Black.
In the Scotch, Black equalizes easily, so I would play Ruy Lopez or the Italian game. For Black play the Sicilian (1.e4 c5) and against 1.d4 play the Semi-Slav.
Hope I helped

I'd recommend either of two categories:

(1) gambits: King's Gambit, Budapest Defense, Elephant Gambit, Latvian Gambit, Cochrane Gambit, Queen's Gambit Accepted, Evans Gambit, etc. (but not Queen's Gambit Declined).

(2) heavy memorization / deep theoretical openings: Najdorf Sicilian, Ruy Lopez, etc.

Youre losing in less than 20 moves to players rated under 1000.  Youre not following Opening Principles, youre missing simple tactics, and hanging pieces.  Openings are the last thing you need to be worrying about.  

Follow Opening Principles:

Control the center.

Develop toward the center.

Castle.

Connect your rooks.

Tactics...tactics...tactics...

Double check your moves.  

Lay off the blitz/bullet, and play longer time controls.  

Do you think you've created enough threads about tactics recently, OP?

You can also refer to this long list of forums with the same question...

I thought that would have been your first post lol.

I try to mix things up every once in a while...

If one really wants a specific suggestion for study as a response to 1 d4, perhaps one could consider The Queen's Gambit Accepted by A.Delchev and S. Semkov.
