Pre-set assessment:
Cities: 4
Workers: 2
Treasury = 2 gold, -1 gpt.
Units: 16 allowed, 7 total, unit cost=0
Tech situation: Amis are up Pots and CB, but down WC
Resources & Luxes: iron and wine hooked up.
Builds: Immortals x2, Walls x1, rax x1
Pasargadae is 4 turns from an immortal, but I can finish an archer in 1 and eliminate any shield waste, with no shield loss. I make the swap, in the interest of getting another attacker up.
Perseopolis is 2 turns out from an Immortal, and I could switch to an archer, but that would be a waste of the five shields about to go into the immortal. Since the Amis do't have WC, the best they've got is warriors and spears, so we can fight them with archers and not worry about getting a GA too early.
1: 1725 BC
A Carthaginian warrior appears from the north! Hannibal appears in the F4 screen. Per rules, I dial him up. I assume (and please correct me if I'm wrong), that I can take a peek at his tech situation.
I DOW Hannibal.

Worker finishes road by Persepolis. Starts mine.
Turn research down to 80%. Alpha due in 7 @ +1 gpt.
2: 1700 BC
Persepolis finishes Immortal->Archer. We need a few more attackers, and archers are cheaper.
We grew a pop somewhere. Alpha due in 7 at +1.

6: 1650 BC
Mine finished by Persepolis. Start next mine.
Persepolis: Archer-> settler (growth in 4, settler in 5, allegedly. 2 extra shields should be picked up on growth to pop the settler)
Pasargadae: Archer->spear (due in 5, to go with the settler)
7: 1575 BC
Alpha comes in on the IBT->Writing. Due in 16 at 80%, +0
Walls complete at Antioch
Take a look at CA2. America is down Alpha, so they can't have Writing. Carthage has alpha, but not Writing (as far as I can tell). With that said, I have to agree that the Philo sling seems unlikely with the detours we've taken.
8 & 9: 1550 BC & 1525 BC(Sorry. They kinda ran together.)
Send workers to chop the forest for the rax at Antioch.
Discover that Carthage has Writing!
10: 1500 BC
Persepolis: Settler->Archer (unfortunately, that reduces Persepolis to +4 sfpt)
Carthaginian warriors finally invade our territory.
vArcher kills rWarrior (1-0)
vArcher loses to rWarrior (1-1)(He's not even fortified!

)
vArcher kills rWarrior (2-1)
I stop here.
The settler can still move. I suggest moving him to Pasargadae, where a Spear is 2 turns out, and then move north to settle. The only question is where. Suggestions?
