custom heroes - AI script

I used the forum search, yet could not find any sufficient threads on that topic.
Thing is that I've got custom heroes with custom hero abilities, custom units, custom researches, custom abilities and all in all a custom game system (it's Zone Control -based, but more complex)
So I'm looking for some tutorials, guides, etc on how to make a good AI for my purpose.
Any help will be highly apreciated

There aren't many tutorials on true AI, but try this tutorial by Blade. It's really all there is. http://www.wc3jass.com/viewtopic.php?t=2474

now that's what I'd call a proper tutorial.
Thanks to you Tainted, and to Blade for writing it.
