Subject: Why can't any programs see this simple Bxh7 sac?

Author: Jeff Anderson

Even most beginners learn to recognize when to play the Bxh7 sac, but for some
reason not one of my engines, commercial or freeware considers it in the
position below.  Even if the win is beyond its horizon, shouldn't most programs
use tecniques to analyse lines like these deeper (extensions I think they are
called.)  This theme so common, wouldn't it perhaps even be in the programs
interest to recognize positions where it could work so they can play it, and not
fall victim to it?
Here is such a position where my expensive programs fail to even consider the
move.
