It's the horizontal distance plus the vertical distance.
Starting at one city, move one province at a time (horizontally or
vertically, but not diagonally) along the shortest path to the
second city. Each time you move from one province to another, add
1 to the distance. You don't count the first city, because you started
there, but you do count the second because you moved into the province.
That's the distance. (Sometimes that's called the "Manhattan distance".)
Some distances:
ck20 to ck27 = 7
cm20 to ck27 = 8
To establish a market the cities must be _at least_ 8 provinces apart.

No. If the tradegood isn't accepted on the first try you will _never_
be able to sell that tradegood in that city. There is a 50% chance that
a city will buy a particular tradegood, which I think uses a hashing
function based on the tradegood ID, city ID, and some other factors;
the important thing is that there isn't any randomness in the formula.
Hope this helps.
