Sometimes as you attempt the Flat Pass your opponent won't give up the underhook and hand fights you instead of pushing to create space. This can prove annoying, but opens up an opportunity to take your opponents back. Once you realize you won't be able to secure the underhook, grip on your opponent's pants (the top leg) and force it to the mat. Sometimes you will be able to pass from here. Most likely however, your opponent will take a grip on your sleeve since your leg will become free, but that is OK. In one motion, step over your own arm, turn on your side, and with your other hand, take a grip on your opponent's lapel. Keep turning, taking your opponent's back as you secure your hooks and control.
