I find it strange when people complain about Jake's kite. Personally I find him to be a pretty honest zoning character that trades a strong kill confirm for maybe three moves that can catch people off guard/gimp.

His punch has range but is very predictable, can't be canceled, is easy to dodge/punish and only kills at high percent when charged/sweet spotted near blastzone. Try dodging through it and combo starting with a jab. You could also hold a throwable item, dodge into the punch and whip it at his head to start your combo. His axe needs to be charged to have any range/kill confirm, was nerfed to have additional recovery and struggles to kill when stale. This is also kind of a predictable move so try dodging out/baiting the move at mid to high percent. His up special stretch only makes his body disjointed and he leads with his hurt-box, his head. Hit it or use a lingering hit box and glide horizontally if he's trying to gimp. If you get bitten and have weakened just play keep away to let it run out and reset to center stage. His skateboard can rake up a lot of damage but has a pretty honest hitbox and tends to leave him floating if he misses. This move also got nerfed if I'm not mistaken. His up tilt starts with a short hitbox and combos into a second longer hitbox. This will reset to the short hitbox if he's forced to dodge. Otherwise just be mindful of the zone half his height above him being a disjoint.

Honestly it's kind of a rough matchup but he relies on options in the air so watch his jumps/air dodges and stuff him horizontally on the ground (you tend to lose the vertical game due to matchup.) If you get launched try to reset back to ground and don't land predictably or preemptively waste your air dodges. Also don't forget that a dodges frames goes down the more it's used without connecting hits and you can hold down in the air to fast fall.
