I am assuming that we do not need to run down both Econ and Martial in order for the Provinces to partially switch to Expand Econ. I don't know if veekie is right and we need to run those both down in order to get them to switch, that's up to you folks who read this. Plus we can always do expand actions and wall actions ourselves (thanks for pointing this out
@Karugus, I had forgotten).
To the analysis.
[][Main] War Mission - Northern Nomads
[][Secondary] Change Policy: Offense
[][Secondary] New Settlement Bleeding Cliffs
This gives us push back against the Khan. Basically gives us the space needed to get our footing. Remember if we lose the March we are gonna be eating a Stability drop.
The Provinces can do a set of Main Chariot for 4 Martial at -2 Econ, one Secondary Chariot for -1 Econ and 2 Martial, and one Main War Mission. All told we and our provinces commit, (thanks for informing me of this veekie), 8 Martial and we end at 1 (+1) Econ. Not the best but gives us breathing room. We need this space and we need to support the March so that Divine Steward's downside of losing Stability if we lose territory doesn't proc.
Next, this grabs requirement 2 our of 3 for Iron. We will need Iron to really keep ourselves safe. It provides 1 Econ next turn and leaves us with 2 Econ then.
In the mid turn it can go a few ways.
We lose out and keep rolling badly which is probable, what this means is that there will be unpalatable options, take the one that keeps us alive and if possible grabbing resources. We will be around 3 Martial at this point and 2 Econ.
We could break even, I think this is likely what will happen. What this means is that we total up and have lost 4 Martial leaving us at 7 a net ahead of where we started, we will also be at 2 Econ.
We could win which I do not consider likely. We will be at 11 Martial or a bit more and at 2 Econ.
Turn 2 I see us doing this.
[][Main] Build Iron Mine Bleeding Cliffs
[][Secondary] War Mission - Northern Nomads
[][Secondary] Grand Sacrifice
With this we get Iron up and running for neutral Stability and give us at least 3 Econ immediately (bumping us to 5), 2 of which would be taken by the Grand Sac (putting us at 3). Resource wise this commits 2 Martial and 2 Econ from us, so we can do it worst case.
If we lost our Provinces will do this: Expand Econ x2, a Main Chariots and a Secondary Chariots to give us +6 Martial for 3 Econ putting us at around 7 Martial if we win and 2 Econ. If we lose again we will be at 5 Martial and 2 Econ.
If we broke even they will do: Expand Econ x1, a Main Chariots for +4 Martial at -2 Econ and a Main War Mission, leaving us at around 11 Martial if we win and 2 Econ again. If we lose we will be at 5 Martial and 2 Econ.
If we won they will do: Two Main War Missions, one created by doubling a Secondary in the Law, Expand Econ x1. We end at approximately 11 Martial if we win and 4 Econ. If we lose we end at 1 Martial and 4 Econ.
With Iron, even nascent, all of our Martial becomes far more effective.
All of these actions are approximates. These make sense mathematically and we have seen that the provinces operate more from the math than not. Some one please correct me if I have made mistakes and point to quotes that support it.
