Harrington v. Arteaga -learning Rybka

I'm posting this game without my comments or analysis because i've been working with the Rybka Aquarium software and learning how to do some different things with it. I took this game which was pretty even throughout and ended in a draw. I then let Rybka do the analysis. He provided his own branches and opening variations which could have been played and gives an approximate evaluation of the position. He also gives his own ?! and ? where he feels appropriate.

This was a Ruy Lopez-Steinitz defense. An opening that is solid for black but not so many winning chances when white plays safe, as I did. I thought it would be interesting to just post the Rybka analysis which will usually help me in my own search but in this case, since its new to me let's take alook at a purely mechanical view of the game. Once again, NONE of this analysis is by a human. Nor did I interfere or cut and paste in any way, this is a full Rybka study.
