If computers cannot see than my first suspect is that it is not winning. I am not sure if the suspect is correct but I do not like criticizing the computers without analyzing the line that they suggest(Ra2 after 0-0 and not Ke1 based on the post because Crafty changed it's main line from 0-0 Ke1 to 0-0 Ra2).
