Focus on stable farming and using passive sustain to outlast Quinn's ranged poke and mobility.
Avoid giving Quinn free ranged harassment windows by controlling space with (Q) and (W) to limit her last-hit advantage.
This is a scale versus early lane pressure matchup; Cho'Gath must survive early harassment and reach multiple (R) stacks for durable front-line presence.
Trading pattern
Fish for (Q) on Quinn's predictable last-hit attempts, then follow up with (W) silence to punish her retaliation.
Avoid trading when (Q) is down or Quinn can kite outside (W) range; reset and wait for better engage windows.
Use (R) to execute low-health targets after short trades, denying Quinn opportunities to punish low mobility.
Danger windows
Quinn is most dangerous when (E) is available to disengage or reposition; avoid committing when (E) is up.
Be cautious immediately after missing (Q), as your engage threat and trading power drop significantly.
Quinn's roam windows after level 6 can leave you vulnerable; hard push to take plates and ping teammates when she leaves lane.
Early game
Prioritize last-hitting inside (Q) range to threaten knockup and zone Quinn from safe farm.
Avoid extended early trades before (R) unlocks; use short control trades with (Q) and (W) when Quinn commits.
Use passive sustain to endure poke and maintain a stable lane state without overcommitting to fights.
Power spikes
Level 6 unlocks (R) execute and health stacking; use (R) to secure kills or objectives and increase durability.
Multiple (R) stacks greatly increase Cho'Gath's tankiness; play front line and force Quinn to navigate your (Q) and (W) zones.
Respect Quinn's level 6 (R) roam potential by maintaining lane control and pinging roams to avoid map pressure.
Win conditions
Control lane space with (Q) and (W) to limit Quinn's ranged harassment and force her into risky positions.
Sustain through poke and scale into a durable front line by stacking (R) on minions, monsters, and champions.
Use your tankiness and crowd control to front line in teamfights and execute key targets with (R) around objectives.
