Indeterminate starting chess positions

[Programmist]

In the general opinion of many chess analysts, classic chess starting position is drawish with a large margin, moreover, results of high level correspondence chess tournaments prove it. The question arises, does every initial starting position have a clear assessment? And what makes the classic position drawish?

Experimental games and some theory show, that positions with different arrangement of black and white pieces are less definite.

In such positions, one side is often stronger and fights for win, while other side tries to defend. This makes chess game with this starting position a two result game effectively in advanced chess.
