If you turn off book and let any program of choice pick a move will they pick
the correct one probably not in the opening and in the transition phase.

this is only on a 500Mhz comp with 64MB for Hash
 0-0-0 is the move to find

If the quote en quote best program out there goes out of book it will likely get
itself into a position sooner or later where it plays the wrong move for an
example look at Nimzo98's win against Chess Tiger

What i would like to know is when are programs going to not need an opening
book. The book didn't help chess tiger this game nor did having a huge speed
advantage i think for Black to realize he has made a mistake and will lose
requires a computer that runs over 5 ghz or faster??
