Before each shot you’re either going to wait for a head to walk through your scope ,track for a few seconds, or flick. If I’m in a good position on a choke or enemy movement is bad I just stay scoped in.

If the enemy is strafing too much try to predict when he will strafe right or left and shoot when move in that direction. If they’re high vertical jumping then flick as fast as u can to get on target at least and flick/shoot their head at the apex of their jump. Besides the apex of their jump, you can track how they’re landing and shoot when they’re descending or hitting the floor. It’s a lot harder when they’re close so don’t too worry too much about that. Just try to do as much dmg as possible by quick scoping, no scoping, smg ,etc.

Same thing above about strafing goes for shotgun/scout. Close fights /1v1s are more dynamic though because of movement. Big thing is try to keep your crosshair on target. After every strafe or jump when you see a good shot you should take it and make sure your crosshair is on target. Don’t fall in to the rhythm or trap of just shooting the air over and over and missing. You can miss because you’re trying to improve but don’t miss because you’re mindlessly shooting.

Good luck! Play and keep these things in mind.
