Generally speaking, since Chun-Li has such a fast LP and fast LK, I’ve had pretty good success just hitting the throw command every now and again while in a block string. If they don’t try to throw you but keep attacking, nothing happens and they continue their block string – your LP or LK doesn’t come out since you’re still in block stun. If they try to throw you, you tech because you’ve been hitting the throw command. If they don’t try to throw and they stop attacking, you turn it around since now your attacks are coming out and you can go back on the offensive.
However, what I have begun to notice is that some players are very good at frame trapping, that is, in their block string they may do an attack that gives them +4 frame advantage, then use a move that has 5 frames startup. In that one frame, if you’re mashing throw, you will give up your block and try to attack, but because no move comes out in one frame, you get stuffed and now your opponent’s hit has Counter Hit properties, giving them even more frame advantage.
So what I was noticing is that some people I’ve played against would scare me out of throw-teching during block strings - so that I could avoid getting punished by the frame trap - then they’d throw me and all of a sudden I was at a reset and couldn’t decide whether I ought to be teching or blocking.
Aside from very good intuition, or excellent reactions, is there a way around this?
