So where can I find these Win At Chess results? On this note,
I did an experiment with KnightCap the other day on some winatchess problems
(Andrew has them in the KnightCap source code directory but I don't know where
they came from . the file is called "difficult.fin"). I changed the evaluation
function to just material and tested on the problems with 30s to find a
solution. KnightCap gets 78% correct, compared to only about 30% with the full
eval.
