While this sounds good, it's not exactly practical.

A program that checks every move in its book will take out all the gambit lines,
although some of the lines may be good and it may be important to have them when
opponents play gambits.

A program that learns by analyzing its own games sounds good too, but nobody
knows how to do this effectively.
