I imagine it'll switch between Bc8 and g6 for a while, which >will take a long time. Yeah, Bc8 and g6 are the two best defenses, and they're roughly equal I think. It will be hard for any program to stick with one of those forever. The really cool thing is that I think the original position is something like mate in 18 or less. I haven't proved this, of course, but the lines in the Informant analysis lead to it, and it seems to be pretty thorough analysis.
