Well I can set up a submission, but I can't finish it. The guy just sits there and my opponent just wiggles out. What do I do? Because I'm rotating the analog stick clockwise while clicking it and hitting the "face" buttons, A B X and Y. It doesn't do anything. Most of the time it sets up a Kamora, atleast thats what the ref says. Any help would be appreciated.

Your opponent needs to be gassed and/or low on stamina.

Pummel they're bodies til they're nackered then go for your submission.

If the character your using has good submission offence rotate the analog stick. If their strength attribute is better then hammer the buttons. This also works for escaping submissions too, with submission defence being the relative stat obviously.

Oh, thanks guys. So is there any certain person who is the best in submission defense and offense in each weight class? Like a list of the best submission people?

Oh. Well is there a video or anything that will show me how to set up an execute a flying armbar or triangle?

yes.
you have to unlock triangle and flying armbar by getting level 2 in bjj i think.
and you get this by competeing the training camp in bjj.
when you unlock it next camp it shows you how to do it.
is a flying armbar the same as a normal armbar coz i cant tend to do a normal armbar in the classic fights but i can do a flying armbar would that still unlock for me?

Well I'm practicing all of this in Exhibition so...how do I do a Triangle in Exhibition?

Okay. Thanks. It's kind of confusing right now, though. I'll get the hang of it sooner or later. I'm amazing on my feet, it's just that at least before if you got me on the ground, I'd be done. But now I'm halfway decent at least.
