There is ALOT of potential to learn with these engines today. In fact, I saw a book recently entitled, (something like) "How to improve your chess using computer software" which I think would offer some excellent tips for us.
One thing that I like the best is how the software is able to create entirely new theory.
In fact, I was shocked to find a new line in the Scandanavian where instead of the queen landing on a5 or d8 (after capturing on d5), it lands on e6+! Finding this has tempted me to want to study the Scandanavian again for completely new lines of play; especially the lines where the queen swings over to the f-h files...
I was also reading on the Rybka site where entirely new ideas on opening theory are evolving from Rybka itself and how Rybka is defeating GM's while being minus a knight!! (error -- Rybka only wins when down a pawn)
I have much more to learn here but I can be confident that no matter what opening system I am examining, I will have a wealth of solid advice and a myriad of candidate options to choose from!
