Instant window smoke from Spawn 6 (left-side stairs, second row of spawns from back wall, in front of garbage bags)

Line up during the freezetime and hold down shift + left mouse button. When the round starts, tap W and jumpthrow, or use a separate jumpthrow+forward keybind.

See instant window smokes from other spawns:
