The main problem is what is the definition of initiative but my evaluation has a
small score that is not based on the leaf position but based on the line that
leaded to the position and I think that it can be called evaluation of
initiative.

I did not test in the last 2 years if the small score that I have help but it
helped when I implemented it and in the last time that I tested it.
