2)The Achilles Crush/Lock: with direct pressure of your radial bone on his Achilles.
3)The Foot Flex(this is what VJ was referencing): With the toes in your armpit, which can also be modified into the toe hold Reilly is talking about.
IMHO the limitations with the Kimura grip is your attacking with the flat side of the forearm vs the cutting edge (radial bone) limits you only to the Foot Flex. However yet another grip the "Outside RNC Grip", on the outside of the leg vs the inside, allows yous to use the cutting edge of the arm to get all 3 attacks mentioned above as well. Not my preferred method but some of my long time students like Sarkis like to use that method when the defender is pulling on the arms break the grip.
