Why Cho'Gath is favored

Cho'Gath can punish an unprepared Jax engage with Rupture(Q)'s knockup and slow, then Feral Scream(W) and a fast Hail of Blades burst before Jax can extend the duel. Feast(R) adds a close-range execute threat, giving Cho a way to win when Jax jumps in before baiting out his abilities.

How to play as Cho'Gath

Use Rupture(Q)'s slow and knockup to set up Feral Scream(W) when Jax jumps in; keep your Hail of Blades burst for after he commits, and use Feast(R) if he is in execute range.

Rupture(Q)'s knockup and slow can set up Feral Scream(W); Jax's Counter Strike(E) avoids attacks but does not prevent these spell effects. (Unverified: no source confirms this note.)

Vorpal Spikes(E) slows after Cho's attacks, helping keep Jax in range for the follow-up Rupture(Q) and Feast(R) threat. (Unverified: no source confirms this note.)

How to play as Jax

Don't Leap Strike(Q) into Cho's ready Rupture(Q). Make him use Q first, then jump in and activate Counter Strike(E) before he can chain his silence and attack burst.
