Well, in general if a program plays a sac it does work - except CSTal and Junior
7 of course. :-)

I prefer programs refuting 9 out of 10 sacs. ;-)
That is the real ratio. (At least) 9 out of 10 sacs played by CSTal do not work.

It is not that easy. You need resources to continue a successful attack. The
