I do not think that his post is going to cause demage to Vas's future.
some similiarity to fruit is natural and I think that there is some similiarity
between every 2 good chess programs.

I also use mobility evaluation in Movei and today it is based only on the number
of legal moves.

What Daniel suggested means that changing it to have different weight for every
piece in case that I decide in the future to do Movei commercial is not allowed
because this idea is taken from fruit.
