Both sides have found the net in the opening half at St Andrews this evening, with Bolton pegging back Birmingham just before the interval.
Hosts Birmingham made the stronger start but it was Bolton who had the ball in the net first. However, David N'Gog's effort was ruled out for offside.
The Blues made their dominance pay after a quarter of an hour when on-loan striker Leroy Lita tapped home Paul Caddis's centre.
Soon after, Bolton's Jay Spearing had his game ended prematurely by injury, with fellow new Wanderer Keith Andrews taking his place.
The visitors got back on level terms just before the half-time whistle when Chris Eagles curled home a 30-yard free kick.
