I found this position very interesting. I don't understand why all the
leading commercial program here need that much depth and time to realize
there is a problem.

I think that biggest weakness in my program, compare to those top
commercial program, is that i don't have a proper kingsafety term.
However, my program fail low on ply 9, switch to b6 and then to g4, all
be done by ply 9.

So i don't know understand this.

(btw, does anyone know how  can I change my email address at CCC,
current one at CCC is wrong)
