Back B Box Jump from B Rafters
This jump is great for getting to a unique spot to cover Garage without expecting any abilities. For the second jump, you need jump at the last possible moment and hold crouch as you reach the box.
Garage 1 Way Smoke from Back B
This one way smoke is useful for holding a B push through Garage and could net you some free damage with your vision advantage.
Heaven Box Smoke from Defense/CT Spawn
This smoke is useful for retaking Heaven when you're worried someone is holding the angle. You need to flick your mouse quickly for this one, otherwise your smoke will get caught on the doorway or go past the box.
B Alley Smoke from Garage
This smoke is useful for denying any defenders rotating to site, especially while you're also mid rotation. To land this, look slightly left to clear the hallway, then quickly flick right then left to turn the corner by site and fly into the wall.
B Heaven Smoke from Garage
This smoke is especially useful for aggressively pushing onto B after you've cleared Back B. The best way to smoke Heaven is to have the smoke land against the side of the wall. If you don't you'll leave a sliver of Heaven open on the right side. To do this, throws the smoke around the corner, flick right right, hold, then flick back left. This causes the smoke to hit the edge of the Rafter and blocks all of Heaven.
A Screens Smoke from A Lobby
This smoke is useful for denying an enemy sniper holding A Long. To land this, wait for your smoke to turn the corner, then quickly pull it to the right and straighten out. As it gets to the back of A Long, you want to pull it to the ground so the smoke fully blocks their line of sight.
