Lurk (lurker)
How it works: while four teammates draw the defenders' attention to one part of the map, the lurker waits somewhere else. When CTs rotate to help their teammates, the lurker catches them from behind, or takes control of an area that the defenders just left.
What a lurker needs: patience, good timing and a strong sense of what the enemy is likely to do. A lurker who moves too early gives away the plan; one who moves too late is useless when the fight happens.
Lurking is risky. If it goes wrong, the team plays the round 4v5. That is why it is usually done by experienced players who read the game well, sometimes the IGL itself.
