wolf's u/f+p ~ f+p+g>> is it not guarenteed?

1. can it work at neutral position? or do you have to make a small forwards dash toward the f+p+g? (i find only works)

No need to dash at all.

2. is the u/f+p struggled easily? it seems though it may just be my timing...

Yes, you can "struggle" after the uf+P to avoid the throw. Just to elaborate, you don't actually "struggle" like you would for a stagger, you just need to input something quickly during the short window where Wolf can enter the throw.

The throw in this hit-throw sequence, like Jeffry's TKoD, is not guaranteed after the hit. The timing for the throw is the same too -- enter the throw input as soon as they begin to recover from the hit (their head begins to rise).

The cool thing about the uf+P is that it has a slight ability to go over low attacks (Wolf quickly raises his front leg before the chop). A nice okizeme tool against low rising attacks!

Have fun.
