If the settler is headed to the W or SW (over the rice road), having the Chariot-W on the hill at Orleans-2SW allows us to cover that. If our Chariot is on the hill at Rheims-2N, the settler could get away to the west, especially if it has an archer escort, which I'd be tempted to attack with both a chariot and warrior backup available.
EDIT: I forgot the chariots can only move 1 tile with fallout. Maybe the hill 2N of Rheims is better...
Here's an idea. Leave the warrior as is for this turn. If dG's escorted settler is going SW, we'll see it at Orleans-SW next turn.
I think it's best to deny this request. We'll get + diplo modifiers with Gandhi for shared religion soon enough, right?
We have to make a decision sooner or later. Are we going to try to get Gandhi to Friendly and have him reserach advanced techs for us or not? If so, we need every possible pluspoint we can get. The problem is, we already kind of screwed that foreve when we DoPed with Roosy. Gandhi always takes -2 for declaring on his friends. So I think we're probably stuck with never gettnig Gandhi to Friendly and planning to ice-ball him also eventually. IN this case, I see no need to give in to his demands. We don't get a negmod from it, just miss the plusmod.
OK. But Moscow can't grow until the rice is farmed (and irrigated via farm chain). So then our build order should be: finish settler -> worker -> chariot X2 while growing to 6 (hopefully Fish can work the gold while we grow) -> GP Farm settler. When do we want to squeeze in the granary? The sooner the better, right? Maybe we could build one chariot and a granary and grow to 7... I'll have to verify that our workers can improve the Copper in time to make this worthwhile.
I agree with what bbp said about granary in 3t after the settler. You actually have to slow growth 1t, iirc, to not waste food, meaning not work the rice 1t. I'm not sure about RAX before or after the chariots. Maybe play that one based on your situational analysis at the time too.
Note that Fish can build a worker or two as well since it currently only has 3 improved tiles to work (4 if you count the gold, which is better worked in the capital for the Bureaucracy + academy bonus).
I would assume we'll be 2popping (or 3popping) FIsh until it gets healthy enough to grow and has tiles to work.
OK, so then Fish doesn't need to build a work boat to net Pigs fish tile if we're building it locally prior to the granary. Should the build queue in Fish be granary (whipped for 2) -> complete work boat (to net the clams NE of Moscow) -> galley (for exploration and to support off-shore settling). Also, if the land mass to the SE is big, we may want to load a chariot onto said galley to explore the inland tiles.
I didn't see the SE workboat either...

I thought that wb build in Fish was taking longer than I had remembered...

. Again, I agree with bbp, let that workboat explore that island freely. And please don't cut corners--you never konw when there are more land tiles off that corner. Or even land tiles that are reachable by a city's second border expansion, which we can also detect by inference if we don't cut the corner.
Churchill has an archer next to our missionary. Do you think he sent it over to our continent on a galley? I assumed that it meant we did have direct land access to him.
I doubt it. I think we're on the same land mass as Churchill, with the isthmus connecting our area to his.
Caution: Careful fog-gazing to the west shows that Mao
probably is blocking us from Roosy and Gandhi. The immediate significance is that our warrior and chariots will eventually be in danger of the 2-3 strike CHurchill archer (starting about 5t from now). If we can't get peace before that, we'll have to really watch out. Note that Churchill and dG will love each other as soon as they meet and share borders, so CHurchill's archer will be able to waltz on over to Pigs City.
On the other hand, if we can somehow worm a chariot past the archer, and get within two tiles of one of his cities, we'll get peace for cheap. Food for thought. The isthmus has plenty of no-fallout plains tiles for the archer to slide by.
