Narrative:
Aircraft #1 climbing to FL330 east/northeast. Nearest potential conflict was 80-100 mi east (wbound at FL310). Other traffic in the sector occupied my time until d-side controller alerted me to close proximity of aircraft #1 and #2. Turns were issued and aircraft #1 descended back to FL290. Climb rate and potential traffic were misjudged.
