Comments.Text: What are you looking for? An absolute number of games won, or the percentage of won games? Only after the first/second white move, or after longer/deeper variations? Or 1. e4 e5 2. ? specifically? Master games or any games a database might contain?

  [This article](http://www.chess.com/chessopedia/view/mathematics-and-chess) says there are 5,362 possible positions after White's second move, so are you asking which of those positions ends in the highest percentage of won games for White? Choosing that move seems a little arbitrary as the cut-off point for the "opening".
  
  On the other hand if you were to look just at the first move, you should be able to find that out quite easily for any given database of games, but you quickly run into problems with sample size. For example, in the [Chessgames.com database](http://www.chessgames.com/perl/explorer) (over 750,000 games) you can see that the most successful first move by this definition is 1.Na3, with which White wins 78.3% of the time! Unfortunately this is from a sample of 23 games...

  Hard to say, as opening trees are biased as number of games played and player strengths are different. And the score difference between best scoring openings is very little, we can say *[statistically insignificant](https://en.wikipedia.org/wiki/Statistical_significance)*. So it's really hard to say.
  
  Therefore, if you ask this for building an opening repertoire, don't do it. But if ask this just for curiosity, then you have the answer.
