I have had the best chess day ever!
I found something so awesome I have to share this with everyone. First I downloaded and installed the scid chess database. It's free and has every feature I could possibly Imagine. I found it here at http://scid.sourceforge.net/download.html
Then I downloaded 1,749,300 chess games in a single file - found it here at http://www.top-5000.nl/pgn.htm
The file is called Million Base 1.74. This sounds like spam, but these 2 downloads are completely free, and I have enjoyed examining these games so much. I used the 7zip utility to unpack the Million Base. Then I used a feature in the scid that I found in the file drop-down menu called "Open as tree"
Guys, you've got to try this.
