firing bullets with KJ

[Julio]

Bluffing in limit hold em is difficult as is, ESP. at stakes this low. But i've posted quite a few hands in this forum, and i have been told that it's wrong only to bet with a made hand. so in this situation, against one player, i figured it was worth a jab. i'd like input on this hand, and when its appropriate to fire bullets in small stakes hold em. i won't reveal the PT stats for this player but he is your typical loose/passive player
