I don't get you, I win because I play drawishly - my opponent eventually gets pissed-off and starts blundering, but, I've been checking openings for a Long time, I can tell you this:
1. Play 1.e4 - that way, your opponents will need to be careful.
Against Caro Kann:
www.youtube.com/watch?v=3gJHE7elWk4He's an IM, he teaches a GM, and he plays the Caro Kann himself, so he knows what he's talking about.
Against French, I play it myself, I think the best is against it is the Exchange Variation - you can attack the eneny king, even though you both castled kingside. I lose quite a lot against it, if I just copycat the moves.
Against Sicilian - choose your flavor, I had great success with simply Nf3, Bb4 or Bc4, 0-0, c3 with d4. - it has no name, your opponent can hardly move in the center.
If he plays 1...e5, you play 2.Nf3
Against the Petrov, you have a Cochcrane Gambit.

-------if he plays either 3...Nf6 (Two Knights Defense) or 3...Bc5 (Italian Game), you play the Double (Scotch) Gambit Accepted

www.youtube.com/watch?v=Sb35_qa3yAM----if he plays 2...Nf6 (Russian Defense), you can play a Cochrane Gambit.
---------if he plays 3...Bc5, you play 4...c3 followed by d4
---------if he plays 3...Nf6, you play 0-0
I know there's also 1...Nf6, Pirc, Scandinavian, Modern, Nimzowitsch, but I don't know... I'm a d4 player for 2 years now.
I myself play the following:
1. As White:1.d4,
if d5 then c4, if Nf6 then Nf3 (2.Nf3 - avoiding much theory, comp's best move, and not committing to c4 - exposing my king, you can play systems - Colle, Colle-Z, London, KIA.. etc, especially if your opponent plays e6 (blocking the light-squared bishop) and 0-0, which is pretty common, don't ask me why).
2. Against e4, French.
3. Against d4, QGD.
4. Against c4, e6 - transposing to a QGD, if he insists on not playing d4, I'll play d5-d4 myself - cramping his position.
5. Against anything else, a Black London System.
Against e4, if you want your opponent to be careful, I'd suggest the French Defense:
Against 1.e4, there are 4 openings who are computer-approved:
1...e5, Caro Kann, French, Sicilian. Sicilian and e5 takes too much memory, Caro Kann isn't your style, I believe, but who knows...
www.chesspersonality.com/It really depends on how cheap you're willing to get in order to scare the opponents, the most solid gambits, you can call them openings, are Budapest Gambit, Benko Gambit, and Evans' Gambit. Ahoy Captain!
