The Secutor slides on the orthogonals like a rook. It captures by colliding against any piece and then deviating to any of the two adjacent diagonals (in the prolonged movement direction). Thus to capture, the Secutor jumps directly to an enemy piece and lands on it, provided that any intermediate squares are empty. The Secutor's value is 3, that is, the same as bishop or knight (preliminary estimate). Other rules are the same as in standard chess, except for the possible promotion to Secutor.
