Narrative:

I received a briefing on the turki-hi radar (93) sector. During the briefing; I noticed that aircraft needed to be sequenced with other traffic destined dfw. Aircraft X was on the txo transition of the UKW9 arrival to dfw; aircraft Y was south of txo direct fuz. My first clearance was to turn aircraft X to a 160 degree heading. I then went on to other things I had noted during the briefing. When I evaluated the status of my vector; I noticed that aircraft X was converging with aircraft Y. I turned aircraft X back on course direct turki intersection. At this point; conflict alert activated. I then turned aircraft Y to a 180 degree heading 'immediately.' I then turned aircraft X to a 070 degree heading 'immediately.' the aircraft turned away from one another but not soon enough to maintain standard separation. I had recently began to wonder if all the time providing OJT was affecting my skills as a controller. I would like to think I can do it all; but this would not be a situation I would normally miss. I do not like to take chances or give risky clrncs. I normally use positive separation techniques.

Title: ZFW CONTROLLER EXPERIENCED OPERATIONAL ERROR AT FL350 WHEN FAILING TO PROVIDE TIMELY SEPARATION VECTORS TO TWO CONVERGING AIRCRAFT.

Narrative: I RECEIVED A BRIEFING ON THE TURKI-HI RADAR (93) SECTOR. DURING THE BRIEFING; I NOTICED THAT ACFT NEEDED TO BE SEQUENCED WITH OTHER TFC DESTINED DFW. ACFT X WAS ON THE TXO TRANSITION OF THE UKW9 ARR TO DFW; ACFT Y WAS S OF TXO DIRECT FUZ. MY FIRST CLRNC WAS TO TURN ACFT X TO A 160 DEG HDG. I THEN WENT ON TO OTHER THINGS I HAD NOTED DURING THE BRIEFING. WHEN I EVALUATED THE STATUS OF MY VECTOR; I NOTICED THAT ACFT X WAS CONVERGING WITH ACFT Y. I TURNED ACFT X BACK ON COURSE DIRECT TURKI INTXN. AT THIS POINT; CONFLICT ALERT ACTIVATED. I THEN TURNED ACFT Y TO A 180 DEG HDG 'IMMEDIATELY.' I THEN TURNED ACFT X TO A 070 DEG HDG 'IMMEDIATELY.' THE ACFT TURNED AWAY FROM ONE ANOTHER BUT NOT SOON ENOUGH TO MAINTAIN STANDARD SEPARATION. I HAD RECENTLY BEGAN TO WONDER IF ALL THE TIME PROVIDING OJT WAS AFFECTING MY SKILLS AS A CTLR. I WOULD LIKE TO THINK I CAN DO IT ALL; BUT THIS WOULD NOT BE A SITUATION I WOULD NORMALLY MISS. I DO NOT LIKE TO TAKE CHANCES OR GIVE RISKY CLRNCS. I NORMALLY USE POSITIVE SEPARATION TECHNIQUES.
