Pop3 arrives on t19, the second mill on t20 because we can't mill river corners (Beijing-1N2W). If we want to slow down chariots, speed up city growth, we could mill the chopped grass and the flood plain first...
I wouldn't be surprised if those lbs are all city garrison or something frozen into the city. Otherwise, we could lure them out with a scout or something and capture the city more easily. So if we lose a chariot+worker, that would be excellent info for capturing other AI cities. We could also go with two chariots. In any case, that cow tile is outer ring, so your bomber plan should work too. Like dG, Stalin is the only one with his religion (Judaism), so he won't be too popular either.
I don't really care that much, but Shanghai is such a good city. Plus, stealing from Stalin starts building roads in the right direction for our future warring.
Ok, let's steal Stalin's capital worker!
Can we use the capital garrison Archer with Bomber vision to steal it on cow starting right now?
Chariot could come help later, and capital has less happy problems and the most need for workers.
