Human Factors
On a climb to FL230 Denver center called traffic at FL240 converging. We were in marginal VFR due to smoke and did not have the traffic in sight until he was flying over us. The autopilot and autothrottle were engaged in VNAV and the aircraft was leveling at FL230 when we received a reduce vertical speed RA at FL227. I disconnected all automation and leveled the airplane at FL228 per RA pitch commands on the Primary Flight Display. The TCAS showed the other aircraft 1;100 feet above us at that point. When the traffic cleared. I climbed to FL230 and we reported the incident to ATC.
