Herlin

A line-piece should come to thematic line beyond the critical square. To accomplish this it first makes a move along the parallel line and by-passes the critical square, i.e. it makes a peri-critical move.

Complete Herlin maneuver: The unit that will be interfered with starts its maneuver from the thematic line.

Alias: Pericritical Indian.
