Are you asking for a opening line where white is winning, like a unsound gambit from black or the first move. I would say that 1. Nf3/d4/e4/c4 are whites best first move options. I like 1.e4 most, but have tried 1.d4. There are black defenses for both these opening that I dislike. 1.c4 and Nf3 are sort of transpo opening or english lines.
