Strong connection

Two groups are said to be strongly connected we the opponent cannot prevent a connection between these groups. The bridge is a strong connection. However strong connections are not always equivalent to actual connections in the way that in order to keep their connection the player has to answer their opponent's threats. The opponent can use this to steal territory. Strong connections are also named virtual connections
