Favour timeline — the windows in Nautilus's game plan

Read from Nautilus's seat: which stage windows this plan plays for against Jax.

StageFavouredWhy
Level 1Even / skillYou both have weak level-1 all-ins, but your passive roots his first-auto walk-up and he has no Counter Strike yet to dodge it — a coinflip that edges you.
Level 2JaxHe hits his power button first: Counter Strike dodges your passive-root auto and stuns you mid-trade before your combo is fully online.
Level 3JaxHis Q-W gap-close plus a stun-ready E lets him pick and win short trades while your W-charged autos get blanked by his dodge.
Levels 4-5JaxThrough 4-5 his Counter Strike eats exactly the sustained auto trades you want, and he sticks to you when your Q escape is down.
Level 6JaxAt 6 his R doubles his resists and his stun beats your follow-up — your Depth Charge locks him, but his all-in is the bigger one.
First itemJaxHis first item, Trinity or Bork, spikes his on-hit damage past your flat tank stats, so he takes over the extended fight.
Two+ itemsEven / skillBy two items the duel evens out — your CC chain keeps full teamfight value while his stat lead plateaus, landing the lane even overall.

How to beat Jax as Nautilus: the early game

Level 1 is your cleanest window — your passive roots the first auto and Jax has no Counter Strike yet to dodge it, so a walk-up to farm hands you a free root-into-trade. The moment he hits 2 and especially 3 the lane tilts: his E dodges your autos including the passive-root one, then stuns you, and his Q-W gap-close lets him pick the trade. Land Q Dredge Line only when his E is down — pulling him in while he can dodge just feeds your W splash burn into nothing. Bait the Counter Strike with E Riptide pokes, not autos.
