I am guessing that you happened upon Zachriel's excellent Civ 3 site. The "main" website with graphical strategy lessons (very cool!) is
www.zachriel.com
In addition, there are fanciful, graphics-laden re-telling of Zachriel's conquests in GOTMs (Games of The Month) - not only very enjoyable, but excellent strategy guides in themselves. Not sure how far they go back (currently at #9), but you can experiment with urls along the following forumla:
www.zachriel.com/gotm9/
www.zachriel.com/gotm8/
etc.
Zachriel: I hope you don't mind me posting the addresses - you seem to do so freely and I think your's is a great site. If you would prefer I not post links (for web traffic or any other reasons), simply PM me and I will desist.

Edited to introduce improper grammar but proper web-link (i.e., removed the period from the end of my sentence

) - thanks for the correction rob.derosa.
