Let's say my opponent (o) has a road network:
o - - - - - o
|
x
as x, can I:
o - - -x- - o
|
|
x
?
And break his already existing road?
My question is not whether or not this will break his road; my question is if it is legal for me to build there and break an already-established road.
At a previous game, there was considerable controversy as to whether this was a legal place to build a settlement.
