I need to know this..reversing moves in the game is pretty easy for me..

Not that I know of as far as I know as long as you press L2/R2 in time the move should be reversed. Also don't forget actual people are better and have quicker reactions than the A.I. Characters in the game.

I find it the opposite. I find countering COM harder. Mainly because I practise against other players online most of the time. With CPU you can basically guess what they're going to do, as they do the same all of the time. But with other players, they change attacks, do different things. When I'm playing players, I tend to just tap the counter button, and I counter more or less all of the time.

In the strong grapple, to reverse strikes, prees L2 as soon as he starts the movement. For example the chop, as soon as he bring the arm back, tap L2.

For grapple moves in strong grapples, you kind of need to have played the player a couple of times before to perfect your countering. You need to know how they play, whether they tend to strike first and so on. So basically practise makes perfect.

I know that when they have you in a strong grapple and press R3 and the selection of moves come up they can do if you have a stored finisher press L1 and there stamina will drop to zero and they will let go
