If you position your knee right and use your weight, you can apply a very unpleasant KOB. I like to place my knee right about at the sternum, that way he is pinned pretty well and hopefully will grimace in pain.
a) If his near arm comes up to block, I like to use my far hand (side by his legs) to get an undergrip on the tricep. From there, I throw my non-KOB leg over his head, pinch my legs together and go for an armbar, making sure I dig myself deep on his shoulder. As my instructor says, "for a good arm bar, you are arm barring his shoulder." Getting it deep makes for a quick tap.
b) If his near arm is tied up, and cannot make use of it, he might try to push the KOB with his far arm/hand. Since my KOB is high up on his chest (sternum), the far hand he pushes off with will be "chicken winged". This will make it easy to grab an underhook; letting go of his near arm, I go north/south while I underhook with my free arm. I then shift to side control, where I set up for an armbar like I described in scenario "a".
Hope this helps.
