Well don't flunk many sword opportunities, also if he spams ice car from across the screen just 6D it if he spams it in the corner instant block and punish. Most Jins I play try to use the same corner pressure with j.B and a string of low attacks then repeat you can do the gravity shield, counter assault or IB and a opening in their pressure I know in CS it's easier for me to 6A his j.B for an anti air counter you can also bait the mashing C if they usually mash C on wake up you can quickly jump over it and punish or gravity shield to counter it. The main thing I try to do always against Jin though is keep the sword pressure and go for a few mix ups trying not to be too predictable with my sword patterns.
