Copying a post that a wrote recently in a separate thread. It was specific to beating panth as jax but I go into much detail on how to win a game vs a pantheon.

For some reason I can't get the forums to formant the whole post the same as item 1 on my list (every time i try to add a space it just ends the list, GG boards)
You should not "beat" pantheon early. ESPECIALLY as jax. Here's how to beat panth overall:
Start cloth armor, 5 hp potions.
Pantheon harasses with q primarily which does physical damage and so the armor helps to lower that damage.
Panth uses a lot of mana on that harrass, the 5 hp potions will help you to sustain through the early harass and make him go oom, or spam less.
Run teleport.
This allows you to get back to lane after taking a lot of harass, heal up and not miss much cs.
This also allows some counterplay to his ult. If he goes to ult mid or bottom lane you can teleport in to clean up kills / protect allies
Be EXTREMELY careful at level 2.
At level 2 panth (especially with ignite) is REALLY easy to get kills with.
For level 2 especially, and really from 2-5 be more concerned with keeping up in levels and last hitting under tower. (yay teleport)
When you go for a cs, he either keeps poking you low with spears, and then flash q stun auto ignite q for the kill, or he trades with his passive and stun(which resets the passive, with almost no practice you can block 3 auto attacks in a row at level 3, or 3 of 4 at level 2).
When you DO trade with him there are important things to remember.
His stun instantly brings his passive back up.
As jax remember to auto him to remove his passive, and THEN w for the extra dmg.
He crits when you are low health (both autos and spears)
This means DO NOT TRADE with him in lane if you think that he might be able to get you low.
Drink those potions/heal up.
His ultimate is almost useless for trading (if you dont stand in the ring)
When you both hit level 6, you get a huge power spike in the form of another ability (usually) while he gets a ganking tool.
If you have been keeping close in trades, you might be stronger now, but at the least you can farm much more aggressively.
The strength of his passive gets less and less as the game goes on. (one auto becomes worth less for your overall damage output)
That's all I have for now.
EDIT:
Not positive but I believe that as Jax if you get stunned while your stun is up, it still goes off. If you are afraid he is about to jump/stun you, active it. You will take less damage dodging the autos, you will take reduced damage from his aoe e, and you might be able to stun him in retaliation.
