Hull City and Nottingham Forest have both had chances to break the deadlock but the home side lead after 45 minutes at the KC Stadium.
Robbie Brady drifted an early free kick just wide before Simon Cox headed straight to David Stockdale as both sides set the pattern for an attacking match.
Andy Reid curled over from 25 yards soon after, before Hull created a gilt-edged opportunity from close range.
Robert Koren's free kick was pushed clear by Karl Darlow but only as far George Boyd, who knew nothing about it as the ball bounced off his head and over the crossbar.
Adlene Guedioura was next to test Stockdale from distance before Darlow kept out Gedo's header at the other end.
In first-half stoppage time Boyd made no mistake from close range to give Hull the lead against the club which he nearly signed for just two months ago.
