lol....... Engared knows my secret. It is close. Thumbs up!
Since this secret have been discovered, I would like to talk about it in details.
At the beginning, I tested it one by one. Afterward, I found out that 33B can replace 66B depends on character's leg position. Anyway, here we go. Let's see what happens.
The moves can do an all-tech-trap after (CH)WS->NSSA+B, NSSA+B, 33B and 44B(hit)B on hit is:
(The characters stand by right leg in front position)
Lizardman - 66B, Delay 33B(Hard)
Setsuka - 66B
Mitsu - 66B
Seigfried - 66B, Delay 33B(Extremely Hard).
Nightmare - 66B, Delay 33B(Extremely Hard).
Hilde - 66B. (Delay 66B for single NSSA+B on hit)
Maxi - 66B. (Delay 66B for single NSSA+B on hit)
Voldo - 66B. (Delay 66B for single NSSA+B on hit)
Astaroth - 66B, Delay 33B(Hard)
Rock - 66B, Delay 33B(Hard)
Cerventis - 66B
Talim - 66B, Delay 33B(Extremely Hard)
Yoshi - 66B
Vader - 66B. (Delay 66B for single NSSA+B on hit)
(The characters stand by left leg in front position)
*** Delay 33B can trap both side tech-roll and hit "play dead->guard" in specific timing against left leg characters.
Sophitia - Delay 33B.
Amy - Delay 33B.
Cassandra - Delay 33B.
Raphael - Delay 33B.
Taki - Delay 33B.
Tira - Delay 33B.
Xianghua - Delay 33B.
Kilik - Delay 33B.
Ivy - Delay 33B(Hard).
Yunsung - Delay 33B.
Mina - Delay 33B.
Zass - Delay 33B(Hard).
Algol - Delay 33B(Hard).
Apprentice - Delay 33B(Hard).
Yoda - Delay 33B.
*** Hard = 1 to 2 frames input windows and it is probably needs a slight step.
*** Extremely Hard = 1 frame input windows and it is probably needs a slight step and different angle.
The input windows of 33B all-tech-trap is like a JF, but it is much easier to do than JF combo like NSSA+B->iaga. I believe that the input windows are around 3 to 4 frames. It is not hard to do.
Since "NSSA+B->Play dead->opponent's guard recovery" is faster than 33B's, the input windows for all-tech-trap and guaranteed ground hit are 1 to 2 frames. Without guaranteed ground hit, the input windows for all-tech-trap are back to 3 to 4 frames.
I recommend to stick with 66B against all right leg characters, and to use Delay 33B against most left leg characters. For some specific characers like Ivy, use both 66B and Delay 33B to guess the right and left tech-rolls, or to use 2A+B for safe play, or to use iagA for guaranteed combo.
These tech-trap follow ups are good because it can perfect the follow up after (CH)WS->NSSA+B, NSSA+B, 33B and 44B(hit)B on hit. After you get these tech-traps, you can apply iagA, 2A+B and 44B for mix-ups and mind games perfectly.
Have fun.
