Subject: question about passed pawn evaluation of crafty

Author: Uri Blass

1)I see in crafty's source code

score+=pscore*passed_scale/100;

What is the meaning of passed_scale?
If I understand correctly the starting value is 100.
I also see in option.c

passed_scale=atoi(args[2]);

I read in the source code that it is done only when "evaluation" command
is used to adjust the eval terms but I am not sure if it can be done
automatically by crafty in the middle of the game.


2)What is the exact definition of connected pawns in Crafty(I guess 2 pawns on
2 files that are clos but I am not sure if they need to be in the same rank)?
