I use scores for order of moves only in gen_push and in gen_promote and in
another file the laphabeta and the move generator are in different files.

I have no type in my program
my move generator has mainly 3 functions
void gen()
void makemove(move_bytes m)
void undomove()
Do you write tyope when you do not know if to write void or int
or anaother varaible that the function may return?

so you say first step to copy the releavent part to .h file and second part to
delete the calculation and add ASSIGN_MOVE_SCORE that may be nothing when I
calculate perft?

so you say that I delete everything except calculation in the .c file?

Do you say to have twice include "movegen.h" in the same file?
