First let us start with two definitions.
Definition #1: A position is said to be normal if there exists a sequence of legal moves from the classical starting position which lead to this position.
Definition #2: A (Chess960) game is said to normalize at move n if the position after move n-1 is not normal, but the position at move n is.
I have seen some games of Chess960 between grandmasters and it seems that whatever the starting position is, the game normalizes quite early.
I was wondering whether there is a correlation between a high level game and an early normalization. The comparison should be made on a fixed position (in position 518, there is no need to be a good player to normalize!), as in some positions like King in f1 between the Rooks in e1 and g1, we can have the feeling that it will take longer to normalize.
One could do the following procedure to answer the question.
- Consider one of the starting positions of Chess960, except number 518.
- For this position, look at each game played. For example, it could be on a fixed website with the same time control and determine at which move they normalize.
- Then look at the correlation between say the average rating between the players and the normalization.
If this is not possible to apply, I would like to collect some factually based opinion about the question.
I think that strong players have a much better understanding of developing phase and can quite quickly reach a harmonious position, which should be normal. Moreover, "weak" players can have the tendency to keep in a nondeliberate way the position messy, hence the normalization process can be long.
What do you think? However, there could be cases where the bishops are at the corner and do not need to move for a while. In this case, the "normalization can be quite long.
