Risk Or Reward

My thoughts on my turn call were that UTG+1 had not shown any aggression pior to his turn bet, so I figured he had a pair of K's at best and I had the open end straight draw with seven outs, 9 [img]/images/graemlins/club.gif[/img] putting three to a flush. Was my risk greater than my reward?
