You pick the dummy (Bang preferred), then pick Mu as the second.
Press record. Have Mu knock Bang down, do the combo, and sj.
Now, you're going to want Mu to practice different things so first, set Mu to doing 5d 6d sj.b. Have Bang wake up and throw like the opponent did. See what happened?
You HAVE to condition. You must focus on the opponent to get a good oki. Mu's oki is ridiculous with conditioning because anything is possible, BUT ONLY WITH PROPER CONDITIONING. ln this case, Bang should get CH'd.
