Next you join a network (click on the triangle in the bottom right corner of Hamachi) and find someone to battle that is also in that network. One person chooses to be host (mode 3 on Redshark) and the other chooses to be guest (mode 4). The guest chooses preferences from the mode choosing window and enters the host's ip address under Network Connection>Host IP. Then, each player chooses start within 30 seconds of each other.
