Cr. HP xx HK (or EX) Pinwheel is Juri’s best punish, as others have said. Sadly it doesn’t do that much damage but it’s still her best option. Unless you have a Fireball stored, in which case you can do Cr. MK xx Fireball -> Cr. MK xx Pinwheel.
@ Above poster. Generally speaking you fish for counter hit combos during pressure strings if you suspect your opponent is pressing buttons. On counter hit you get more frame advantage, which allows you to do combos you wouldn’t normally be able to do. I don’t know what Juri’s specific counter hit set ups are, but for example, with Chun-Li you can combo a sweep off of jab on counter hit. You would look for this set up by delaying one of your jabs in a block string to counter hit the opponents crouch tech, and then combo immediately into sweep.
Regular combos work great on counter hit too. For example, Ryu can hit confirm plenty of shit off of CH Cr. MP, which also happens to be a pretty great move to use while pressuring. Standard variations include, Cr. MP -> Cr. MP -> Sweep, or Cr. MP, Cr. MK xx whatever.
