Somewhere else the 200M is mentioned (as a peak?). The text also mentions
DB doing some pre-processor stuff (I think).
Quote:
"Deep Blue uses "live" software that can actually generate up
to 200,000,000 positions per second when searching for
the optimum move. The software begins this process by
taking a strategic look at the board. It then computes
everything it knows about the current position, integrates
the chess information pre-programmed by the development
team, and then generates a multitude of new possible
arrangements. From these, it then chooses its best possible
next move."
