Had a quick look at game, no real micro manage idea's..BUT!!!!
1) Why focus all espionage on Hammurabi?? I thought we were going to own Churchhill. Seems the best fit for Conquest. Use Spies to take down city defences, he only has 4 Espoinage to spend, while Hammurabi has 20 4 more then us.
2) Court houses, if not for Maintenance saving, the Additional Espionage is helpful, we should consider running a Espionage slider against Churchhill.
3) I made a mistake about the off shore Islands, I assumed that we had the Great Lighthouse, its now only worth 2 trade routes, 6 Gold total at best. Though the bottom 3 are close to Rome, and would pay for themselves.
4) Time has come to Expand Via the Sword. Churchhill is just asking to gift us some cities, 2 Stacks, 1st to Take out York, Via a spy to drop defences, the 2nd being linked with 1st to take out London, and essentially crippling Churchhill. 2 moves, 3rd move we take York, Immediately move on London, while awaiting cultural expansion, linking up with 2nd stack, Take London, solves a lot of the Problems in the South.
5) Catherine Know's Currency, I'd sell it to Churchhill 1st, then sell it to all others for the cash alone. Better to get something then nothing, and Make a move on Churchhill after doing that.
On the War, swapping Churchhill into No State Religion, which we adopt, after building the Attack force, would remove the Friendly status that he currently has with Both Hammurabi and Catherine, they are only Pleased with us.
Wrangle some sort of Peace deal with Catherine on the Turn of War Declaration, we have 10 turns to do our damage. That should give sufficient time to take London, York, and Hastings, and move onto Warwick.
Looking at the Peace weights from the
BTS Reference guilde Catherine can bribed at any status to attack, but will attack at Pleased. Hammurabi, won't declare or be bribed at pleased. Catherine is far enough away that she could be enticed to join in a war against Churchhill, if we move him to No state Religion, as we don't have any other religion to move him too.
Scout out that City of Hammurabi, to the NE of Churchhill, if only for the Additional trade routes from knowing a city.
