Narrative:

With an RA on climb out to pahokee climbing through 11000 ft with a visual contact at 3 O'clock position and 500 ft below and climbing, the RA directed a descent 2500 FPM and at the same time the controller directed us to expedite climb. As captain, I commanded the first officer who was flying to follow the controller's instruction as the safest response. By following the RA directions we would have descended through the altitude of the visual target. The expedited climb to FL230 resulted in the traffic to pass behind and below. I observed the traffic as 3 mi horizontal and 500 ft vertical at the closest point. I believe controller error in having a close encounter, but used captain's authority/authorized to deviate from a commanded RA instruction.
