White always starts the game of chess with an advantage that is worth approximately 3/10ths of a pawn. Any sound opening system has been researched and analyzed for years ( that's what goes into all those opening books) to maintain this advantage from the opening till the middle-game.
Not to sour your hopes of finding the "best" opening but there are several that allow white to play with this very basic "advantage".
There a few that are riskier but give White a "huger" advantage ONLY if black doesn't defend well or perhaps does not know the theory. Once again => at the highest levels of chess, these types of risky openings (gambits etc.) are seldom seen for obvious reasons.
what i the best opening for white that gives u advantage
