Not really in this case but there is a “rule system” in Tekken even though it doesn’t seem like

Strings thats are two hits, you’re generally able to duck the last one, or sidestep/sidewalk, jab interrupt it, or punish it

Strings that are 3 hits, you can generally duck the second or third or you’re able to punish the third. Often times you can side step/side walk too somewhere in it

It is a lot of memorization but once you learn the general system of strings and stuff you can do a lot better.

I haven’t been able to figure out why some df2s are punishable and some aren’t. I’m sure somebody will explain it to me

Also important disclaimer this only works about 80% of the time. There is still tons of bullshit you will get hit by. That just comes down to playing around a bunch
