The first line I can think of is 1.d4 d5 2.c4 dxc4 3.Nf3 Nf6 4.e3 e6 5.Bxc4 c5 6.0-0 a6 7.a4. It provides a decent game, and I can't think of any way to get slaughtered early.

Or are you worried about any of Black's possible deviations? Is that where you get slaughtered?

As white my main opening is d4 followed by c4. Normally this works well for me, as most people play the tarrasch, slav, semi-slav, etc.. but it seems like I'm getting roasted against the QGA early on in the opening. Is there a good way to learn how to handle all the early tactics black can try against white? If I can get the game beyond the beginning I tend to win, but I have been getting caught with tactics against good players before the game really even starts.
