Oaty,

I wasn't trying to imply that you were attempting to exploit the AI. I didn't read what you wrote that way at all. Like you, I've seen those scenarios where I really just wanted to stand there (strategic map) and force the AI to either sally or starve. However, this AI flaw (actually the AI exploiting the human for a change) has required me to conduct sieges more rigorously than really should be necessary.
