The most important thing to know regarding this match up on the defensive side is this.
Always block low. The reason being is that the most effective overhead jin has is his (I think?) 6A. The move where he swirls his sword and hits with the hilt, it's extremely slow and very easy to see and punish with an IB. This is one of the main reasons against Ragna most Jin players prefer to play the punishing type, because of their poor mixup, and the fact that if they botch it up, they will be easily punished.
In that respect, the match is simple to control, since any over exertion of the Jin player will leave him at a disadvantage.
Oh and IB the shit out of Ice car that shit is mad slow xDDD.
