Scout,
There is a distinction that I think needs to be made here about Chi / Ki. What is being described in the other posts is being aware of Chi within your own body and is a useful first step. However if you want to be able to know your partners intent then you need to develop a more comprehensive awareness.
The first step is to understand that Chi never stops. It is the energy of life that is in everything. Next understand that we are all nothing and everything, in other words we are all one thing, and that one thing is nothing. Zen meditation can get you there, but like they say it can take a few years, but in truth it takes just a moment of awareness.
In the Indian Yogi philosophy it's called Prana, and they understand that this energy is just a manifestation of your thoughts, emotions or Mind. Your goal is to be in charge of your mind. Stop any thought that is not NOW. At this point you will begin to notice that any thought sends out energy and you will start to percieve the difference between your energy and others energy.
Once you can detach from yourself you can take it to the functional level beyond the physical. How you do this is by keeping your center, pushing out the energy (or more accuratly your awareness of Chi). So get centered, push out that energy to fill the area around you, remember to go under the ground as far as you go up, to go forward equal to backward, left equal to right... you get the idea.
Once you can do the above you will "feel" the intent of everyone around you and be able to respond in the correct manner.
Now for some practical things you can do to get in touch with the energy while waiting for your enlightenment experience, you may have already had an enlightening experience, it's not like I can tell from here

.
First get centered.
Now rub your hands together, pretend you are holding a ball of energy between your hands. Compress the ball and expand the ball. Feel it. Now make sure your focus is still on the ball of energy in your center. Understand that there is no difference between the balls. Find the connection, of how the energy flows in your body. The feeling of chi is NOT chi, it is just your body reacting to the energy flow. Those who tell you that chi is the heat or whatever are missing the point. You get heat/sensation as a byproduct.
Second find a partner (this can be anyone, significant other, child, etc...).
Get the ball of energy going till you can feel it strongly, then slowly move it back and forth close to your partners hand (held away from the body). You want to feel for differences in the "pressure" without touching. With practice you will be able to feel when the other persons Chi is touching you, vs when your chi is touching there chi or your chi is touching them.
Third
Start at a distance of 10 feet and with energy up (fill the space around you) slowly approach the person and feel when your energy contacts them. You want to create a very stong "presence" at the limit of your range. Thus you will feel when they are in contact range (don't forget to go underground). Do the same exercise as in step two, but with your entire body.
Fourth
Be able to change the energy of your center to effect the person. In this step you begin to understand that the only energy that can be in your presence is energy that is already inside you. As Dr Dyer says, what do you get when you squeeze an orange? Orange Juice. Why? Because that is the only thing inside the orange. If you get squeezed (someone applies pressure to you) then whatever comes out has nothing to do with them, but everything to do with you. What this means is that you can send out relaxing energy to have them relax, or create fear, doubt.. any emotion really.
Last
Blend with the energy around you. Allow it to express itself while not changing you. Now you will know what they are going to do as they think it. With your MA training you then choose the correct response. At this point your energy awareness permiates everything around you.
