I'm going for the fastest Diplo again. Justjohn embarrassed me last game, so I hope he’s going for it again... and neilmeister... and several others. I want to earn the award, not get it by default because I'm the only one going for Diplo. Note: my diplo actually sucks. I used to ignore it completely as I usually focus on Conquest or Domination. Who needs friends anyway?
I decided to go the peaceful route. I settled in place and then founded a city to the SW for gold/copper (2360 BC) and the NE for gold/copper/silk (1520 BC). I wanted two additional cities to the north as well: one to the NE for corn/marble/pig (and later found out horses too) and one to the NW for pig/corn (and horses too). I felt this would seal off Churchill. When my settler arrived at the NE location, Churchill had a settler one step away. I settled and his settler started heading toward my NW location. My settler would arrive about 3 turns behind his so I declared war and used my two warriors to block his path. This worked to keep him from MY spot and he ended up settling a bit further west. At least I got MY spot. I later razed his city and sued for peace.
Of course, this had a price. Two prices, actually.

First, Churchill had a wandering warrior to the south that I didn't know about who came out of the fog and captured my undefended second city. I took it back the next turn but I had lost 2 pops (one when he captured and one when I captured back), a granary and 75% of a worker.

The second price wouldn't manifest itself until centuries later... but the first price was a major early setback that I would have to overcome.
My initial tech path was TW -> Pottery (I wanted sugar cottages to fuel my research and allow me to still grow while working the gold mine) -> Mining -> BW -> Writing -> Math on my way to the CS sling.
I made an early mis-click. I thought my warrior was selected but it was actually my worker. The worker had just finished the corn farm and sugar cottage and was supposed to head toward the gold. Instead, I sent him two tiles to the east.

1 turn east and 1 turn back west = two lost critical early worker turns. It means that my gold mine was two turns later which snowballs as the game progresses. Luckily my mouse didn't break after it mysteriously bounced off the wall.
OK. So I lost my second city and my gold mine was set up two turns late. I needed to take a gamble if I wanted a chance to take the fastest diplo. I've got 3 gold mines and 2 sugar cottages on line. Screw the CS sling, I'm going for something BIGGER!! No wonders have been built yet and this is Noble so I can safely delay the Oracle, right?
I research to PH and then CoL -> CS -> Masonry -> Paper -> Education sling in 475 BC! I did it.

But at what price? I had to ignore a lot of critical early techs like Alphabet, AH (no horses and no pig pastures) and IW (no iron) for 100s of years. Plus, I don't have 6 libraries yet so I can't even start on the 6 universities required for Oxford. Finally, I got CS (and Bureaucracy) about 600 years later than had I just Oracled it in 1440 BC. Let’s see if the gamble pays off…
At 1 AD, I had 10 cities (all self-built other than one barb city taken in the SW with sugar and spice and everything nice… unless you don’t like 15 jungle tiles in your BFC.

I had 40 pops, 9 of my 10 cities are Confused, 8 workers, 5 warriors, 3 axes, 2 spears, 7 granaries, 5 libraries, 1 monastery, Oracle, 5 half-finished universities, all ancient techs plus Writing, IW, Alpha, Math, Literature, Calendar, CoL, CS, Paper and Education. Bureau, Slavery and Organized Religion. Copper, iron, horses, marble, gold, sugar, corn, pigs, and (almost silk and spice).
The biggest questions at this point are:
Did losing my second city set me back too much?
Were the sacrifices made for the Education sling worth it?
Would the decision to delay hooking up the gold until after a sugar cottage (and a misc-click) come back to haunt me?
Would taking out either Churchill or KK lead to a faster victory than a peaceful approach?
Will justjohn, neilmeister or someone else embarass me yet again?
And, most importantly, will my mouse survive another impact with the wall should something else bad happen?
Time will tell...
