(10) turns played at last.
1310 AD:
I set Guimarães to workers. It won't grow much without biology anyway and has a very suitable hammer count. 12 hammers when working the town gives +3 from expansive bonus and +3 from the forge.
1330 AD:
We suffer a diplo hit with Saladin.
As mentioned Izzy gets SM this turn so I trade SM to Saladin and Liz.
We get economics+gunpowder from Saladin and RP from Liz--there were some small lump sums of gold involved.
Moscow finishes the university and gets started on the Moai Statues. In hindsight maybe the NE would've been better together with the NP, but on the other hand MS will get the NP up much quicker for faster research towards ecology. NE+NP would be 550 hammers (would take forever) so I went for quicker gain.
I get ready to do the fm+fr civic swap but I notice that it's at 2 turns!

I decide to skip it altogether and wait for a GP to start a golden age. There are still civs in mercantilism, so FM isn't that urgent. I hire a prophet in the capital to shorten the wait--it will pop 1450 AD. When it's popped I suggest major changes (caste, fm, theocracy, christianity).
Isabella has switched to christianity and at the end of the set Kublai went for FR, so adopting a religion seems very good now. As Izzy is now the founder of her religion there's more friction in the world of politics and we'll get extra +.
While waiting (hoping) that chemistry would be allowed for trade I went back in the tree and finished monotheism+theocracy (theology).
We're the 2nd largest civ.
1410 AD:
Saladin and Liz will part with chemistry--yay!
I give Saladin RP and 115 gold for chemistry.
Observant eyes will notice that noone has communism yet.

We would've gotten it, but if I was placed in the same situation (with the same information) I'd do the same thing. The biology path has worked out great anyway as we got to trade chemistry--we've plenty of gold to rush biology.
St. Petersburg finished a settler this turn. We can choose between settling 1 or 2 cities. If we opt for 1, I think the tike I'm marking below is the best, but we could squeeze in 2 as well.
KK adopted FR+emancipation+US 1400 AD which gives him 2 turns of anarchy I believe.
Now that KK is out of HR I think we should stop supplying him with dye. He's creative so I bet all of his cities have theatres for +2 happy.
