Narrative:

15 miles out from pickens county airport (lqk); the first officer was on COM2 listening to CTAF and advised traffic where we were and what our intentions were. There was only 1 aircraft in the pattern and we exchanged radio communications with them. Greer approach cleared us for a visual approach; frequency change to CTAF; [and] we joined up on the visual from the IAF on the GPS 23 fix. Greer had advised us that there were two targets; one of which they were talking with who was the aircraft in the pattern; the other they were not. The aircraft in the pattern was aware of our position and intentions. We were on about a 4 mile final for runway 23. The aircraft who was not utilizing radio communications at an uncontrolled field was north of center-line heading north when suddenly it turned right to a south-southeast heading. We were descending on the visual approach during this. Our TCAS told us to descend; which I complied with. He passed overhead by approximately 400-500 ft. A possible preventative measure could have been to overfly the field at traffic pattern altitude; but I am not sure what that would have done aside from making the flight several minutes longer and burning more jet fuel. We had advisories from approach and were in communication with the aircraft in the pattern and they timed their pattern accordingly. Thank goodness we have TCAS technology!
