Prioritize stable farming and passive sustain to reach your health stacking power spikes against Vayne's high mobility and ranged poke.
Avoid giving Vayne free space to kite and punish missed (Q) or (W) cooldowns by controlling wave and zoning with your crowd control.
This is a scale vs scale matchup where Cho'Gath must manage medium lane pressure and outlast Vayne's early agency through cooldown punishes and objective executes.
Trading pattern
Fish for (Q) knockups on predictable Vayne movement near minions and follow with (W) only if she commits to trade.
Punish Vayne immediately after she uses (E) to knock you back or when (W) silence is available to block her retaliation.
Avoid extended trades when (Q) or (W) are on cooldown since Vayne can kite and outdamage you with true damage autos.
Danger windows
Be cautious when (Q) is missed as your engage threat drops and Vayne can exploit your cooldowns to poke or all-in.
Respect (E) wall stun and level 6 stealth (R) to avoid getting locked down or kited in tight spaces.
Early lane before tank items and (R) stacks is vulnerable to Vayne's true damage poke; avoid extended trades and overcommitment.
Early game
Focus on farming safely and using (Q) to threaten Vayne when she last-hits near minions to create short control trades.
Avoid long early trades before (R) and tank items to reduce vulnerability to Vayne's true damage and mobility.
Use (W) silence to interrupt Vayne's engage attempts or escape when she commits to trades inside your zone.
Power spikes
At level 6, use (R) to execute low-health targets and secure stacks, shifting lane pressure and objective control.
Multiple (R) stacks turn you into a durable front line; force fights through your (Q) and (W) zones to capitalize on this.
Respect Vayne's level 6 (R) stealth repositioning and (E) wall stun; avoid committing when these are available to prevent being kited or stunned.
Win conditions
Use (Q) and (W) to control space and zone Vayne away from minions, denying her safe farming and scaling.
Survive lane through passive sustain and stack (R) to become a durable front line that punishes Vayne's fragile state.
Transition into objective control and front-to-back teamfights where your health stacking and execute threaten Vayne and her team.
