Hi.
I don't know why they made so much errors in this position, I have'nt fount
errors in the rest of the book (cd) that contain more than 4k analyzed
positions. Editorial misstake or user inputs that was forgotten to be checked?
They have added computeranalysis to each move (cap data) so you easily sees the
error when you browse through the moves.
There are many other similar position analyzed (without error) to go
through/learn before one are able to analyze this by hand, so please post your
corrections. Since you are so involved in this problem, maybe you could make a
web-page for it.
I tried to run the position with Gandalf but didn't get any where, it still stop
after some thinking. Maybe I didn't used the update version, I have to check
this.
I can run some analysis when Shredder 9 comes out to see if I find anything to
add, or maybe one of the beta-testers want to try it now.
