Tahm Kench should control the lane through durable short trades and deny Singed the ability to proxy or disrupt wave control.
Focus on using passive stacks and (Q) to punish Singed's attempts to force bad chases or proxy pressure.
This is a control vs teamfight matchup where Tahm Kench must survive early disruption and reach mid-game durability to protect carries and isolate targets.
Trading pattern
Build passive stacks before committing to trades, then use (Q) to slow or stun and follow up with (E) to absorb retaliation.
Avoid trading when passive stacks are low or (E) gray health is depleted to prevent Singed from punishing your durability.
Punish Singed if he misuses (E) by engaging aggressively while his displacement is down.
Danger windows
Be cautious when Singed's passive stacks reach three and (Q) can stun, as he can follow up with (E) displacement.
Avoid chasing Singed through his (Q), especially when (W) grounding and (R) combat stats are active.
Watch for (E) cooldown; engaging immediately after it is used reduces risk of displacement.
Early game
Use (E) gray health to absorb Singed's poke and engage only when passive stacks are near three for a stun.
Avoid extended chases through (Q) to prevent getting slowed and flung.
Prioritize short trades that build passive stacks and use (Q) to slow or stun before Singed can ground or displace you.
Power spikes
At level 6, use (R) to isolate Singed or protect allies from his disruptive engages rather than for damage.
After your first tank item, take advantage of increased durability to convert passive stack threats into lane control.
Respect Singed's level 6 (R) speed and durability boost by avoiding extended chases and preparing to counter his disruption.
Win conditions
Win short melee trades by building passive stacks, landing (Q) stuns, and absorbing damage with (E) to deny Singed lane control.
Use (R) to isolate Singed during skirmishes or save allies from his disruption to create pick opportunities.
Maintain wave control to prevent Singed from proxying or forcing inefficient rotations, setting up mid-game teamfight impact.
