When I first heard about the idea, it sounded crazy. Crazy enough that it might just work!! Now kids, dont try this at home, you need a special set of conditions for this to work. You for one have to be Turks (since this strategy uses the Turks powers to the fullest). If your target happens to be Lakota (well you have hit the jackpot then!!)
Notice the above screenshot (its the 7th minute), what the Turkish player does is focus on booming, he builds many villagers (since they are cheap and fast), and gathers a decent amount of resources. With the surplus villies, he scouts for ruins. He ensures that he does Mil2 before he hits Classical age (that way not only military researches are cheaper, the siege is also available). On hitting Classical age, he builds not one but two siege workshops (since each workshop gives 2 free siege weapons for the Turks).
He also has ensured that he as a tower built, in Classical age, he researches Militia, which as we know is an extreme defensive tactic to fight an invasion.

Build a senate and research Despotism. That way your villies get a +2 attack bonus. Also build a university in the background and have one scholar at least, this is your back-up plan in case you fail to retain the capital – in which case now you can safely boom.
Now, the money move … he gathers all his villagers and converts them into militia. That as his defense for his siege engines, he launches an attack on the hapless capital of his enemy. 7th minute, 4 siege engines … that’s fast.
Like all rushes, this move also depends on knowing beforehand the location of the capital and scouting.
