There's no real way to set this up, so I'll just tell you what you are required to do.
The opponent will use three moves: Punch, Counter, and Grab. Punch beats Grab, Counter beats Punch, Grab beats Counter.
In order to "block" them, you just have to perform the move that beats them. Since there is no way to set this up, you basically hope for the best. I got this achievement in the first match I played, so it's not a rare one.
EDIT: Just wanna add, if you are seriously having trouble with any of the achievements, you can get most of them in local co-op, including this one.
