Walk into the corner shown, then line it up with the edge of the window shutter and the top edge of the section sticking out of the building. Start running straight forward and you should get pushed to the right automatically by the pole. Then, as your crosshair reaches the top portion of the window, do the jump throw. You'll end up landing on the car and the smoke grenade should bounce to block off CT spawn. Useful for a lurker staying back to set up a mid push from this team.
