Round 4: 1750 BC to 775 BC (39 turns)
I started the round by making a few of your suggested adjustments. First of all, I took advantage of Spiritual to change civics and avoid a slave revolt in the capital:
I also changed Mecca's build from the Pyramids to a Granary to help support the anticipated whipping I'd be doing there. I kept researching Writing.
A few turns later, I was back in Slavery to whip the granary to completion and put the overflow towards the Pyramids:
Slobberinbear's concerns about that eastern copper tile were correct:
Can I just say I
hate being next door to a Creative civ? I don't care if Zara is the nicest guy on the block, he dies for this.
Some good news: my Warrior survived an encounter in the jungle with a barb Archer (thanks to Woodsman II and the fact that the clueless barb attacked from across a river) and earned Woodsman III. So now I can build the Heroic Epic whenever I'm ready.
The Heroic Epic is going to be needed, given the current state of the power chart:
That is worrisome, and it's something I'll have to address--but probably not until the next round.
As you may have noticed, my economy gradually recovered from the expansion I did at the end of the previous round, so Writing came along sooner than it looked at that point:
Which meant it was time to expand again:
I'll have to farm every tile I can in order to make that city viable since it has no food source. I guess I should have moved it 1W to get the corn, but I was following Validator's dotmap and trusting his wisdom. Fortunately there's a lot of river tiles and I'm planning on running a SE, so farms aren't a problem.
Meanwhile I decided to try out that walls-chop-whip-to-gold trick. I built Walls in Mecca to within one turn of completion. Then I got two forest tiles to chop on the same turn...
...and I then whipped the walls to completion.
This resulted in a ridiculous amount of overflow, something like 270 some-odd hammers in total.
And on the next turn, holy crud, it worked!

264 gold!
I immediately pushed the science slider up to 100%, using the gold to accelerate research. I was going after Iron Working as recommended, as you can see. This gold allowed me to finish IW and two more techs before the end of the round. Astonishing. However, it feels kind of exploity, so I don't know if I'll use it again. It was fun to try it this once, though.
Some good news on the diplomatic front, in my opinion: Suryavarman declared war on Roosevelt!
Since Sury is the furthest civ from me and doesn't share any borders with me--unlike the other two jokers--I'm going to try to keep him as happy with me as possible. Maybe he can keep Roosevelt preoccupied while I take on Zara. Of course, when it's down to just the Khmer and myself, all bets are off.
I finished IW; I'll show you where the iron is on the map at the end of this update.
As I said, I wanted to keep Sury happy, so that meant turning down FDR when he came by with a request:
That dropped him to Annoyed, so as I said before, I'm going to have to beef up my military in the next round. Granted Sury is keeping him busy for now, but if peace breaks out, Roosevelt may come my way.
I researched through Hunting so I'd be able to get the Elephants happening, and then finished my next Protective-leveraging tech at the end of the round:
Besides taking advantage of Protective, I felt the need to beef up my military. And what with losing Medina's copper, and Baghdad's is going to take a while, Archers were attractive... especially since my only source of iron is far, far away:
You can see that there are two other sources to the NW and SE, but both have been snagged by my neighbours. So I'll have to get a Settler down to the south coast ASAP.
The Pyramids are nearly complete--11 turns away! I'm having a Worker perform one more chop, then I'll let them finish on their own. After that, I think the next round will have to focus on Settlers, Workers, and military units. Madrassas are available, but I think they'll have to wait.
(By the way, notice that black corn tile at the far SE corner? That's right, a barb city is helping me block Zara!)
As for research, I was thinking of Alphabet next; my Great Spy is less than 20 turns away from appearing in Mecca (assuming the GE points from the Pyramids don't change that), and so I'll need Spies to take full advantage of his appearance. Regardless, it's high time for Alphabet anyway.
But as always, I'm open to suggestion and persuasion. Bribes too, now that I mention it. I'm not proud.
