With Cho'Gath, stack Feast on minions whenever it is off cooldown: it is a scaling resource, not just an execute. Chain the knock-up into the silence to guarantee the cone connects. In teamfights, look for corridors and save the ultimate for the first enemy carry dropping below the true damage threshold.

The first ability knocks up for 1s, which guarantees the cone from the second connects; the third chains all three spikes during the 60% slow left behind by the first

Land the crowd control first, check the remaining health, then release the ult: 300/450/600 TRUE damage is reduced by no resistance whatsoever

Here the silence goes first, not second: it cuts the assassin's spell chain before it even begins

Cho'Gath is generally played as Top. The first objective is to respect true-damage duelists (fiora, camille, gwen) and ranged champions: play under tower, farm with e and never give a free q. a missed q means 6 s with no answer. Its biggest edge comes from permanent scaling: every successful feast adds health, size and attack range kept for the whole game.
Cho'Gath takes over in mid game: the champion changes nature from 3-4 feast stacks: the hp, size and attack range he gains make him impossible to trade with 1v1. that's the window to take fights around the first dragon and convert them into plates.
Cho'Gath can be punished when zero mobility: no dash, no leap, nothing but base movement speed. A practical answer listed here is: Punish every missed Rupture: a 6-second cooldown is a completely free trade window.
