2 | Units may move to any square that is guarded by more friendly units
6 In addition to their usual abilities, pieces may jump to controlled squares,
7 that is to say squares attacked by more friendly pieces than enemy pieces.
8 The king in check may only move as in orthodox chess, but "rampage" moves
9 of other pieces are allowed to cover the check.
10 Pawns cannot promote with a rampage move.
13 Attacks on the same row, file or diagonal are cumulative. So,
14 on the next diagram the marked square (e5) is guarded twice by each side:
15 "rampage" moves to that square are impossible.
