NL100 6 handed at PP. im fairly new to table. on the button i get black JJ. 3 limpers to me, i raise to $15, all folded to UTG who calls. FLop is (3 [img]/images/graemlins/heart.gif[/img] 4 [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/spade.gif[/img]). UTG then opens for $15, i put him all-in for $82. he calls. he turns over A [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/heart.gif[/img]. he does not improve, i double up. im just interested how much of a favorite was I after the flop? he had many outs. how would you of played this?
