Narrative:
Air carrier X requested climb from FL290 to FL330 due to turbulence. It was a busy sector so I asked pilot if he could be level in 3 mins. Pilot responded, 'no problem.' issued a climb clearance using prescribed phraseology for pilot to be level in 3 mins or less and issued current time. Air carrier X acknowledged. Took handoff on air carrier Y opp direction and latitude offset at FL310, coming from mia ARTCC. Air carrier X handed off to mia ARTCC. Mia controller requests air carrier X on heading 100 degrees to go around air carrier Y. Issued turn to air carrier X. Air carrier X acknowledged but did not turn and sep was lost for approximately 20 seconds. Pilot should have initiated turn but did not until level FL330.

Title: ACR X HAD LESS THAN STANDARD SEPARATION FROM ACR Y. ACR X FLT CREW FAILED TO TURN AS INSTRUCTED. PLT DEVIATION.
Narrative: ACR X REQUESTED CLB FROM FL290 TO FL330 DUE TO TURB. IT WAS A BUSY SECTOR SO I ASKED PLT IF HE COULD BE LEVEL IN 3 MINS. PLT RESPONDED, 'NO PROB.' ISSUED A CLB CLRNC USING PRESCRIBED PHRASEOLOGY FOR PLT TO BE LEVEL IN 3 MINS OR LESS AND ISSUED CURRENT TIME. ACR X ACKNOWLEDGED. TOOK HDOF ON ACR Y OPP DIRECTION AND LAT OFFSET AT FL310, COMING FROM MIA ARTCC. ACR X HANDED OFF TO MIA ARTCC. MIA CTLR REQUESTS ACR X ON HDG 100 DEGS TO GO AROUND ACR Y. ISSUED TURN TO ACR X. ACR X ACKNOWLEDGED BUT DID NOT TURN AND SEP WAS LOST FOR APPROX 20 SECS. PLT SHOULD HAVE INITIATED TURN BUT DID NOT UNTIL LEVEL FL330.
