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.

These are asymmetric starting positions. I like Chess960 better (you can play it for instance at http://littlegolem.net).
The "trick" is, to find the weak spot, normally f2/f7, but in Chess960 that changes. He who attacks first (usually white Wink) has a nice initiative.

Weak spot regards,
Paul

I am talking about advanced chess games and engines games with long time control, not human games.

What I am trying to say is, that I see no point in analyzing asymmetric starting positions. I do not believe they will ever be used for normal chess tournaments.

Almost all Chess960 starting positions are clear drawish in advance from my experience, because of black and white pieces have same arrangement, and advanced chess tournaments with this positions tend to be draw.
