In the match, when an opponent throws a punch at you, or attempts a move, you can attempt to reverse the move by pressing
away from your opponent. This achievement is a little confusing. Some reversals you do - blocking a punch, and throwing one yourself - don’t seem to trigger a reversal, even though the commentators pick up on it. One it does pick up on though, is a knee to the gut, so if you hit that, you know it’s going to count. You don’t get this in the middle of the match, so you’ll have to count them yourselves, and you will get it at the end of the match.
