@Bede,
A is a spot that blid marked for grabbing Marble. I think it's a good spot.
B is the six-hills spot I talked about.
C and D I added just for fun - debatable, as are A and B.
C we'd have to race with Asoka to get to, and even if we got it we'd probably end up fighting an Indian city for the Rice. But it would still get the Cow and it would clear an excellent path to Delhi.
D looks good to me, but we can't see it all, and we don't know where Iron is.
@blid,
About the possibility of Oracle/MC/Pyramids, yes. You have to get the Oracle built early enough (anyone have an idea when that is for Monarch/Epic?) and then you have to get the Forge built quickly, exactly as you said. And if you want to be certain of getting the Engineer you have to build the Forge in a different city from the Oracle. It requires planning and micromanagement. I don't think I've ever tried it.
If we did it, here are my thoughts.
If possible I'd prefer to settle both Marble and another city (say, B or D) and build the Oracle there. Otherwise we'd have to research IW and develop Marble City enough that it can build the Oracle itself (113 Hammers with Marble.) Then build the Forge and Pyramids in Moscow.
The forge is 180 hammers. We could pre-chop Moscow's forests or pre-build Mines over them. Pre-Mathematics we get 30 hammers per forest inside the fat cross.
Moscow, at its happy cap of 5, can work Cow, Horse, and 3 hills. (I don't know if replacing one hill with fish for whipping is better, but assuming 3 hills...) With no mines, Moscow's hammers are 1(city) + 3(horse) + 2(cow) + 6(grass forest hills) = 12. Then each forest that's replaced with a mine gives +2 hammers. Suppose mines were fully pre-built on Moscow's 3 grass hills, although that feels overly optimistic to me. Suppose we haven't yet built roads on those tiles. Then the Forge build could go something like this.
Turn 1: 12 hammers, worker finishes mine #1.
Turn 2: 14 hammers + 30 for chop, worker moves
Turn 3: 14 hammers, worker finishes mine #2.
Turn 4: 16 hammers + 30 for chop, worker moves.
Turn 5: 16 hammers, worker finishes mine #3.
Turn 6: 18 Hammers + 30 for chop.
That brings the hammers to exactly 180.
Or, since Moscow can pull 18 hammers without chops, if its mines were all fully built ahead of time, Moscow could finish the forge in 10 turns minus a couple turns for a concluding whip.
@by the way
I'm pretty sure that a partially built improvement prevents the growth of jungle. Therefore we got there in time, could build one turn's worth of a workshop (or of the forbidden imrovement) on top of the bananas, protecting them from the jungle and enriching Marble City (if it was built where blid marked.)
