AI recognise Persian douche?

So, the latest challenge require us to beat the extreme AI 1 v 1. And I am not at that level yet. However I do want to unlock that so I try to cheese it by limiting the game to stay in dark age forever and try to Persian douche the AI. To my surprise, the AI preemptively recognise what I am going for even before I send out my villagers to his base and start building houses around his TC to prevent my douche. Obviously it is the Persian douche and it is still the AI so that never stop me finding a TC spot. AI's Villagers and militias just can't stop it from going up. I shot down like 3 TCs before finally winning the game and "complete" the challenge. But the AI's ability to recognise it, try to prevent it (even before I start sending out villagers) and try to rebuild after being douche is still amazing. I don't know what gives it away. Is it because I am Persian and the game only set in dark age, so the AI was programmed to react that way? Or is it when it saw me going for stone?

Anyway, this is interesting to see and for those noobs like me who have no hope to win 1 v 1 against extreme AI, here is the way to cheese it 😂😂😂
