Mind/body connection is something I am also interested in exploring. For example, I can often tell when I am going to miss a basketball shot by feeling a creak in my kness. Sounds crazy but I'm sure there's a reason for it. This is a different phenomenon from people anticipating when it's going to rain by feeling pressure.. I think it's something like my predictive intuition has been working in the background outside of conscious awareness, and only becomes conscious through tells that I've learned.

You seem to be in the right track about the mind/body connection. Daniel Siegel has this to say about Intuition (see the "The Mindful Brain"):

Intuition seems to involve the registration of the input from the information processing neural networks surrounding our vicera; for example, the heart, lungs, and intestines. Our body's wisdom is then more than a poet's metaphor, it is a neural mechanism by which we process deep ways of knowing via our body's parallel distributed processing surrounding these hollow organs. This input registers itself in the middle prefrontal cortex and then influences our reasoning and our reactions.

This was the only index on Intuition in that book. Going by this definition of intuition, you should feel it in your chest or abdomen not your knees. But I'm really new to this, so I'm not going to claim to know anything:-)

Have you read The Inner Game of Tennis?

Not yet. I will eventually. Thanks for the reminder.

Maybe you miss your shot because you get distracted by your knees creaking? :)

It's possible, attention and performance are intricately linked (c.f. http://hpl.uchicago.edu/Projects/Projects_1.html). However I find that the knee-creak is also a predictor of things I no longer have control over (and for which I am only awaiting an outcome). Of course, I'm biased, but I think the heuristic is useful for me.
