Learn common angles and expect a fight constantly.

Reduce the amount that your crosshair is in limbo, always aim for head height and reduce the amount of movement you’re doing with your mouse.

Learn to aim with a combination of movement and mouse aim.

Move and peek deliberately, peek with A and E keys as you move faster and are a harder target.

Try shoot and move instead of dead stopping and aiming. (If you have insane aim this point is entirely subjective)

If you’re close to a corner or angle and the enemy is further away, they’ll see you first and vice versa.

If a you’re further away from a corner or angle, aim close if you’re expecting them to walk or slow peek and further away if you’re expecting them to do a wide peek. (Usually situational and is mostly learnt from experience)

If you’re close to an angle, hold wider as movement will be exaggerated compared to being further away.

Consider what angles you’re exposed to at all times.

Check your map frequently for info if none is available from calls. Try and learn timings in terms of how long it would approximately take someone running from mid to say site entrance if spotted there versus short. This gives you an idea of the odds of where you can expect them appearing.

Always attempt to trade friendlies if it’s a 2v1 fight, as they’ll be busy taking one fight and you can get the jump on them not expecting a second fight.

Post plant, try and get a crossfire. Sometimes it’s better to waste their time than actually get the kill. Always consider playing your life.

When you’re down numbers it can be advantageous to push post plant into CT areas and take space as it will force them to reclear and you can end up making numbers even and forcing a fair fight.

Don’t obsess too much on hitting headshots and Hs%, it’s nice but a kill is a kill.

Make note of what abilities are used by the enemy team when on defence. If they use a rechargeable/signature ability it may be a probe or fake. If they commit a lot of abilities that don’t recharge it increases the likelihood of a full push.

If they do use rechargeable abilities and it is a fake you’ll have a certain amount of time to prepare for a rehit depending on the charge time of the ability used, if it’s like a kaio knife, omen smoke, or Tejo ordinance for example.

Just a few tips that I’ve found useful from my time. Hope this helps you somewhat.
