Peeking: wide, jiggle or shoulder, and when each one wins

You know someone is holding the angle. You peek, they shoot first, you die. Next round you peek slower, and they still shoot first. You conclude they have better aim, and sometimes that is true. More often you peeked the wrong way for the situation, and the way you peeked handed them the fight.

Most players have one peek. They walk out at a fixed speed and a fixed width and hope. Good players have three, and the choice is made before the corner: what do I need from this peek, and what is the holder expecting?

Peeker's advantage is real. In an online match the player moving around a corner sees the holder slightly before the holder sees them. A wide, fast peek exploits that. But the advantage disappears if you peek slowly, because a slow peek shows the holder a sliver of your model for long enough to shoot it.

The holder, meanwhile, has crosshair placement on their side and a known spot to watch. A jiggle takes that away by showing them something to react to without giving them anything to hit. A shoulder peek baits their shot, or their utility, without committing.

Three tools, three jobs. Using the right one is worth more than a month in an aim trainer.

1. Wide peek to take the fight. When you have decided to fight, and you know roughly where the holder is, swing wide and fast with your crosshair already at head height on their spot. Counter-strafe as you arrive, shoot. Do not creep. The peek is a commitment and creeping is the worst of both worlds.
2. Jiggle peek to gather information. Strafe out just far enough to see the angle, then strafe straight back. Half a second at most. You are looking for whether someone is there and where, not trying to win the duel. If they fire, you have their position and they have nothing.
3. Shoulder peek to bait. Show a shoulder for a moment and pull back. Against a player holding a scoped weapon, this often pulls a shot they now have to recover from. Against a team it draws utility. Then take the real peek while they are recovering.
4. Never peek the same way twice in a row. If you wide peeked and died, the holder is expecting the same. Jiggle the next time. If you jiggled twice, they will pre-fire the jiggle, so wide it. The variety is the weapon.
5. Decide before the corner, not at it. The peek fails when you arrive at the corner and hesitate. Say to yourself "wide" or "jiggle" two steps before you get there.
6. Practise the movement without enemies. On an empty map, pick a corner and drill each peek ten times. Wide with a counter-strafe at the end. Jiggle with an instant return. Shoulder that never shows more than the shoulder. Then go to deathmatch and use only one of the three for the whole session.

Watch your deaths after a few matches. When the peek was right and you still lost, that was aim, and you can take it to the trainer. When the peek was wrong, no trainer would have saved you.
