Andy's other question

When starting can my claw go over the fence?

Not the edge borderbof the feild, but as long as your not trapping the other team or touching the ground you can go as far over as you want

After the start of the match, you may expand past your required 18"^3 and past the fence as long as you DO NOT not any tiles on the opponents side.

This is seen in the Official Game Manual as SG6:
