I think that a squeeze (done right) should be thrown in occassionaly between pinching and rollng the nipple with your fingers. I like to apply pressure to the nipple with my palm and make circles, that is always a good thing to throw into the "squeezing" of breasts. Pinching is fun, but i far prefer suckling and nibbling. While "down", alternating rhythm between nipples, in a complimentary rhythm to the tounge movements, is a good technique, but dont do the same stimulation, or rytymn on each nipple, pinch one while pressing the other for example, but rhythm is the key. Sorry if that TMI, but hey, we were talking about nipple play, so i had to contribute.
