Hi Everybody !!!
I think the main question of Carlos Alberto was not answered.
"If I can't put influence tokens in the sea area with enemy fleets, how do I establish a naval route to the sea zone affected by the enemy fleet?"
And a have the same doubt .... !!
I missed the original question in 2014
Anyway: a naval route to an arbitrary sea zone "X" requires a continuous sequence of tokens starting in Venice and passing through ALL zones from Venice to X, EXCLUDING the zone X itself... you need actual tokens on the sea zone X ONLY if you want to place (other) tokens on the colonies adjacent to it, not when you attack enemy fleets in the sea zone.
