Ok, this is some other options to trying to break the grip when you go for an armbar and the guy defends by grabbing his hands together.
Let's assume you are attacking the right arm, so sitting off to his right.
First the obvious, if we are doing MMA hit the guy, start hammer fisting his nose, he'll probably want to defend it
Second, a note on breaking the grip if that is what you choose. Different grips break different ways, and at different angles. If he is holding his right wrist with his left a goose neck wrist lock should release it, if it's a c-grip a slap at the angle his finger tips are pointing should do it. Think about how his grip is and where the weak spot is, attack that. Don't just pull with everything you got.
ok, on to a couple other options...
Grab the opposite side elbow, pull it in towards you straightening that arm, wrist goes on shoulder, keep the legs tight and pressure down on the elbow. If it fails (which truthfully it often does) that is fine cause you broke the grip and have the first arm.
Slip your right foot between him and his arms, keeping it on the far side of his head, let him (or help him if needed) sit up and take the triangle.
Assuming your right wrist is in the crock of his elbow, flip your right leg over his arm to the near side of his head, triangle your legs (right foot in left knee) around his bent arm, keep your wrist at 90' too his arm, thumb up so the boney parts are up and down, pull it in too you and squeeze your legs for a bicep crush.
I got a few others and am now stuck at trying to explain them in text, so that's it for now
