The players have equal speeds. They can observe each other at all times. We study a new variant of the game in which the lion has only line-of-sight visibility. Hence, it can observe the man's position only if the line segment connecting them does not intersect the boundary. We show that despite this limitation the lion can still capture the man in any monotone polygon in finite time.en-USReport
