I'd like to focus on flip for a second. Are you sure you have the right replay? Because the replay shows you and some guy named Fallensoul, "fighting". Nothing in the replay resembles a flip. You might want to get that checked out...
As for counterring, just use common sense. As if it were happening in real life. Ask yourself "what would I do in this situation?".
Example: Someone grabs your arm, you counter by manipulating that arm, or any part of the body that would change your chances of winning. I'll add a replay of what I mean later.
