Go up one level in this thread

As to what I mean as 0:  At that level it would be a random move generator.
You can get weaker than that but there is no point.

As to a program being weaker than anybody would need:

1.  Some programs don't even come close.   The lowest "rating"
on fritz 5 when running on a Petium II 400mhz is 1350, but that
rating often beats me at speed chess and I am strong A player.
The only other way to weaken the program is to change the way
it evaluates the position, or tweak the "blunder range" value.

2.  What if you were teaching chess to a small child?  I want to
start teaching chess to my 4 year old nephew, who might not be
much better than a random move generator.  Even most beginners,
child or adult, need something pretty weak to practice against.
