Make lots of changes as detailed in my previous post.
1410 AD (1)
Trade units with Monte on the IT, call the war off. He pays 20 gold, WM and 5 gpt for peace. We should get the circumnavigation bonus on the next IT.
1420 AD (2)
I guess someone else circled the globe first. Huh.
Whip Theater in Tlatelolco. If the city does flip, we'll leave a lot of carcasses behind. Current risk: 2.29%. I think starving it down to size 1 and growing back with Turks will reduce the risk.
Since the circumnavigation bonus is gone, trade our WM around for 400+ gold.
1430 AD (3)
Printing Press in, go for Replaceable Parts hoping we can trade for Gunpowder.
Whip Theatre in Icy Fish. Theatre completes in Tlatelolco, revolt risk down to 1.43%. With two forced Artists, the city makes 32 cpt and will starve to size 1 next turn. Then we free up tiles for it again.
1440 AD (4)
Reported flip risk in Tlatelolco is now 0%.

Starvation still works wonders. Allow the city one more turn with a forced entertainer, then we can start growing to coincide with the 100-culture border pop.
1450 AD (5)
Roosevelt declares war on Monte.
1460 AD (6)
Tlatalolco has its 100-culture pop and now controls the cow + other tiles. Time to grow.
1470 AD (7)
We pop a Copper near Border Fight.
1480 AD (8)
Replaceable Parts in, start on Nationalism. Retaining hope we can trade for Gunpowder.
Izzy starts a GA via Taj Mahal.
1490 AD (9)
Now Toku declares on Monte. In a separate event, Toku starts a GA.
No good deals exist for Nationalism and Gunpowder is still not available.
1500 AD (10)
Nothing much happens.
Final Notes:
The flip threat at Tlatelolco is over. We won't get a lot of tiles, though, without a war on Izzy.
Monte is going to get reamed by Toku. We may want to join in to expedite Monte's demise, which coincidentally will free up Toku for another war. We need Nationalism, Gunpowder, and Rifling to be in a position to draft our UU. We should have enough money for 4-5 Maceman upgrades as well. I did not make Toku and Izzy stop trading, but this could be accomplished with Liberalism. I didn't do it yet because I didn't want us to have to do it twice before a war could break out. Izzy does not have a supply of Horses, so there should be very few Conquistadors in her army.
Thanks to the Copper the Heroic Epic will complete next turn in Border Fight. More culture, and a doubling of troop production rate. In 4 turns we will either get a Great Scientist or a Great Engineer from Iznik. The Observatory will let us run a third scientist when we choose. Icy Fish may be trying for an Artist.
Our first Lumbermills come online soon, and we should have three cities able to build troops for the next 10 turns. I would figure we are still 10 turns from our UU unless the Great Person wants to research Rifling or the AI is less stingy with Gunpowder. Since we have Copper the Statue of Liberty is in play for us.
