Dealing with opponent trying to pass your hand behind your back

Dealing with opponent trying to pass your hand behind your back

Q: How do you deal with someone who does nothing but pressure you from inside your guard? Doesn't get the pass or the sub, and sometimes they'll just lock arms behind your back and keeps putting all his weight on you without moving. I'm a patient guy so I wait for them to open up eventually, but I'm afraid this might be a bad strategy for competition or mma. How do you create space or sweep/sub in this situation?   / d85lak7
