Sixth sense (abbr.) (3)

Ross

I believe the answer is:

esp

(Other definitions for esp that I've seen before include "Apparent power to perceive things that others can't, initially" , "Extrasensory perception (abbrev.)" , "Second sight (abbr)" , "Apparent power to perceive things that others can't, in short" , "Initially, clairvoyance or telepathy" .)

I've seen this clue in The Washington Post, the Universal, The Star Tribune and the Newsday.
