  I would recommend that you take a look at the **Silver Openings Suite** by [Albert Silver](https://chessprogramming.wikispaces.com/Albert+Silver). It's a hand-crafted set of 50 opening positions designed for balanced play, based on some non-trivial statistical analysis using [ChessBase](http://en.chessbase.com/post/test-your-engines-the-silver-openings-suite "ChessBase").
