Kennen controls lane pressure by poking with (Q) and stacking marks to punish melee approach windows against Teemo's poke style.
Prioritize ranged poke and avoid prolonged trades to deny Teemo safe scaling and trap setups.
This is a teamfight-focused matchup where Kennen must leverage flank angles and (R) to outplay Teemo's trap control and blind.
Trading pattern
Trade short bursts with (Q) and (W) to stack marks, then disengage before Teemo can retaliate with blinded autos.
Avoid extended trades when (E) is down as you lose mobility and become vulnerable to Teemo's poke and traps.
Punish Teemo when his (Q) blind is on cooldown by committing to quick mark stacks and short all-ins.
Danger windows
Be cautious after using (E) as you become vulnerable to ganks or all-ins without mobility.
Avoid grouping in choke points when (R) is down to reduce risk from Teemo's trap setups and poke.
Respect (Q) blind timing, as trading into it without your stun stacks or (R) ready increases your damage taken significantly.
Early game
Use (Q) to chip Teemo early while maintaining distance to avoid his blind and poison autos.
Keep (E) ready for escape rather than engage until you have clear vision of traps and Teemo's cooldowns.
Pressure Teemo's attempts to trap river or brush by sweeping and poking to limit his side-lane control before level 6.
Power spikes
At level 6, preserve health and look for flank or flash angles to use (R) for area stuns and teamfight impact; Teemo must respect your ultimate's threat.
Hold (E) and (R) for decisive fights rather than low-value trades to maximize your kill potential and teamfight presence.
Respect Teemo's level 6 trap control which can punish your engages or retreats if you do not clear vision.
Win conditions
Use ranged poke to control the wave and stack marks, then convert (R) flank or flash windows into kills or objective fights.
Deny Teemo trap control by sweeping and punishing his side-lane pressure to maintain lane dominance.
Leverage your teamfight strength by flanking with (E) and (R) to stun grouped enemies, turning lane pressure into mid-game impact.
