Attack zone

Definitions: A cell is reachable from an edge if a straight line of diagonal bridge jumps can be made between the cell and the edge:

R4 C8 Vg1 Se2 Sc3 Pf1 Pf2 Pd2 Pd3 Pb4 Pc4

A cell is doubly reachable if diagonals can be made in both directions:

R4 C8 Vf1 Sd2 Sb3 Sg2 Sh3

The Attack zone for a certain edge consists of all cells which are doubly reachable from that edge.
