[youtube=Xianghua Crouch Throw Tech Trap Demo by Bad Idea]pL4_cBLFVkE[/youtube]
(copied from Youtube link)
The tech traps you will see in this video utilize Xianghua's 22_88K; a tech-jumping mid kick with a bit of a slow startup. It's a bit hard to land, but it's +2 on block and it forces FC, so it's relatively safe if you can get a chance to use it. On HIT, however, it places the enemy right at your feet with +frames on you. The best part about it? It catches techs on ALL SIDES.
Now then, a breakdown of the video demo:
0:00 - 22_88K, 2A+G - A basic tech trap. Rings out front and slightly to the right of Xianghua.
0:07 - 22_88K, 2B+G:B+K, 6A+B, 66, 2B+G:B+K, 6A+B, 66B+K - The alternative, and the meatier one too. Once you land 2B+G, you can continue with the staple combo (6A+B, 66B+K). HOWEVER, as you can see in the video, you can omit the 66B+K, run up to the opponent, and grab them AGAIN if they tech! It's a double tech trap!
0:19 - Teching Forward - Easier to grab. They just tech right into your arms.
0:31 - Teching Backward - Tricky. Except maybe the first grab, they're likely to slip away. You'll have to step a little farther to catch them going backwards, but it IS possible to catch them.
0:40 - Teching Left - Also tricky. They roll opposite of Xianghua's grabbing hand, so you'll have to step a little further to help your tracking.
0:51 - Teching Right - Easy. Rolls right into her hands.
1:08 - 2A+K, 2B+G, Staple - The timing on this one is a bit tricky, but opponents who expect the K or 2K followup might accidentally tech on reaction. It's also a low, in case your foes start to expect 22_88K. You'll also notice from this point onward, I keep flubbing up the staple ._.;; But you know what it looks like, right?
1:18 - 4K, 66, 2B+G, Staple - This one requires quick fingers and a bit of chasing, but for everything 4K already does for you, it nets you a tech trap too? Swell!
1:27 - 3AK, 66, 2B+G, Staple - The second K is blockable on normal hit, but both hits go in on CH, so that's when you follow up. Requires a bit of chasing; backwards teching may elude you.
1:37 - 44KB, 66, 2B+G, Staple - Another mid option, but faster than 22_88K. The 'stun' shock might get an opponent to try and 'shake' the stun, thus forcing them to tech, and that's when you sneak in for the toss. A bit of footwork involved, back tech may escape.
1:51 - Well, it speaks for itself.
