for the river valley tile micro 
I did two things and ended turn:
- I put Cannae back to 2 scientist specialists and 1 merchant. Normally merchant is indeed better in Cannae, but this turn with 0 % research the case is a bit different. This turn we are also running 2 scientists in Agincourt, which means that we want to also run 2 scientists in Cannae it gets us to 4*3*1.25 = even 15 beakers. Yeah, it's a small thing, but just wanted to type down my reasoning.
- I also moved the bows from Peterloo into a more central position, because we will have 10 turns safe borders in west and there is always a change that we need those against suttree. We should be able to bring them back in time to gather some fortify bonus if we are not worried about suttree.
