Wide Peek / Swing:

A wide peek, or swing, is when a player moves out from cover farther than a small shoulder peek to quickly expose an angle and take a duel. In Counter-Strike 2, it is used to clear common holding spots, challenge an opponent’s crosshair placement, or gain information while making the peek harder to hold with a single pre-aimed shot.

Wide peeks are often timed with teammates, utility, or sound cues, and they are especially useful against players holding tight angles.
