It was said on the other thread, I'll repeat it here... the aim is not to get even but to GET AWAY.

Do not try to take them on... try to GET AWAY.

Do not kick them in the squishy bits, it's a very small target and you could easily be overbalanced and pushed to the ground... if you really must, use your knee, your centre of gravity isn't changed so much and you are still fairly stable and able to GET AWAY.
