IMHO if the code for evaluation is taken from Crafty and changed a little,
it will play worse than Crafty.
Also I don't consider sharing of ideas as plagiary. Can anyone show
chess program that does not account material during evaluation?
I don't use the code of Crafty as source of code or ideas, but maybe
I will return to it for ideas if my program will lose badly, to recognize
what is going on. Is it a proper usage of a chess engine code?

It doesn't matter how different they are in behaviour. For example, I
could take a copy of the Crafty source and change the evaluation routines
so that all the pieces have negative value. This would play completely
different moves from Crafty but is certainly not my original work and
therefore would be disqualified from the WCCC (well, it would be if people
could stop laughing at it).
