Narrative:

I was the supervisor getting currency on radar position. Aircraft X was a pointout at FL350 going wbound. Aircraft Y was at pointout going eastbound a FL370. We then got a third pointout on aircraft Z going northbound at FL370. As we were the only ones aware of all 3 aircraft, I took action as both aircraft at FL370 were wired. I took radar on aircraft Y and got control. I turned aircraft Y right and got clear of first clump of wbound at FL350. I then issued descent to aircraft Y to FL330. About 2 mins later during moderate traffic I noticed both aircraft X and Y aircraft were still a problem. I turned mine further right and instructed the other controller to turn aircraft X hard right. Separation was lost shortly after with the closest point being 600 ft vertical and 3.2 NM lateral. I failed to insure some form of separation at all times.

Title: SUPVR CTLR WORKING A HIGH ALT SECTOR AT ZBI LOST SEPARATION BTWN 2 ACR ACFT OPPOSITE DIRECTION.

Narrative: I WAS THE SUPVR GETTING CURRENCY ON RADAR POS. ACFT X WAS A POINTOUT AT FL350 GOING WBOUND. ACFT Y WAS AT POINTOUT GOING EBOUND A FL370. WE THEN GOT A THIRD POINTOUT ON ACFT Z GOING NBOUND AT FL370. AS WE WERE THE ONLY ONES AWARE OF ALL 3 ACFT, I TOOK ACTION AS BOTH ACFT AT FL370 WERE WIRED. I TOOK RADAR ON ACFT Y AND GOT CTL. I TURNED ACFT Y R AND GOT CLR OF FIRST CLUMP OF WBOUND AT FL350. I THEN ISSUED DSCNT TO ACFT Y TO FL330. ABOUT 2 MINS LATER DURING MODERATE TFC I NOTICED BOTH ACFT X AND Y ACFT WERE STILL A PROB. I TURNED MINE FURTHER R AND INSTRUCTED THE OTHER CTLR TO TURN ACFT X HARD R. SEPARATION WAS LOST SHORTLY AFTER WITH THE CLOSEST POINT BEING 600 FT VERT AND 3.2 NM LATERAL. I FAILED TO INSURE SOME FORM OF SEPARATION AT ALL TIMES.
