Many CS newcomers are still unclear about the concept of "Super Jump." They mistakenly think that a leg-pushing jump (crouch jump) is the same as a super jump. In fact, a super jump is "spin jump + bunny hop + spin jump."
How to do a super jump in CS
(Taking spinning to the left first as an example)
a. Keep your crosshair at about 45 degrees downward, run forward, jump, and release the forward key.
b. Hold the left key while smoothly moving the mouse to the left at a steady pace.
