Narrative:

Exceeded 200 KTS below class B airspace. Takeoff was from opf, which is 10 NM north of mia. We were given an initial altitude clearance of 2000 ft. The class B floor was 3000 ft. Level, at 2000 ft, airspeed increased to 230 KTS. No other abnormalities. No comments from ATC. This was third leg of day which began at XA50. Fatigue played some part in this, as well as unfamiliarity with airport. Opf is not a normal destination. Did not realize that we were below class B airspace.
