From my understanding you can feint with hidden stance. Let's say (poke- heavy cancel) or just (heavy cancel) soooo why am I having so much trouble with this?! (chain cancel block) maybe? havent found anything about this super clutch ability
Side note: dueling orochis. I'm pretty sure the move you're using is the cheat code from gtavc to spawn a tank... just stahp. At least until I figure out feint. Not that I'm mad about it hahah. haha. Hah :/
You can't enter hidden stance while changing stance. If you feint High Heavy and try to hidden stance, often it misregisters as a right or left and change stance instead of going into hidden stance. If you are playing with keyboard...then i don't know. Part of it is reading the animations too. You need to know which part of the animation cancels out. i would recommend you watch this video.
