My reasoning for not raising the flop, having the relative position to the bettor were:
<ul type="square">[*] There was no draw to make it two bets and therefor wrong to call[*] I didn't believe any King was gonna fold[*] Because of the size of the field and action pre-flop I figured I was more likely than not behind and drawing not ahead and charging[/list]
I don't know if raising would have been better, but that is what passed through my head. A two suited board or two cards closer in rank together for a more likely straight draw and I would have had to raise the flop to give me the best chance of winning.
