What is your strategy to defeat the Hard/Hardest Resonance Bot 5.1c on an open map?

I can beat the regular hard HD AI without much of a problem, but the Resonance Bot still manages to be a notch better than me.

My basic strategy against the regular AI was either just a knight rush or a Feudal rush with archers and spears. It typically can't fight back for long and even if it has a feudal army, I can usually just overpower it with onagers in castle age.

However the Resonance Bot has it's towers and is typically much faster at making military than the HD AI on hard. It tends to use a lot more onagers and other siege than the regular AI as well, so it is difficult to win an extended fight.

I've been looking for some videos or guides, but it seems like there aren't a whole lot of people playing against the Resonance Bot.
