Briar vs Cho'Gath

Cast Blood Frenzy (W) only when you want to end the fight: you charge the nearest enemy, champions first, without choosing your target.

Save Snack Attack (W) for when you're low: your next auto deals damage based on the target's missing health and heals you for part of it.

Fully charge Chilling Scream (E) near a wall: the scream then knocks enemies back, and those who hit the wall are stunned.

Cast Certain Death (R) across the map to engage or catch a target: you fly to the first champion hit and chase them until they die.

Keep moving against him: Rupture (Q) strikes an area on the ground, and an enemy standing still takes a knock-up, damage and a slow.

Punish him when he goes for last hits: Carnivore (passive) restores health and mana for each unit he kills, and he lasts a long time in lane if you let him farm.

If you have range, keep your distance: his kit has no dash, only the slows from Rupture (Q) and Vorpal Spikes (E).

Don't stay in melee range at low health when Feast (R) is up: its true damage ignores your resistances, even if you're a tank.
