im not happy about getting ai on the flop coz i think he folds a J sometimes and has a [img]/images/graemlins/heart.gif[/img] an awfull lot, leving me crushed or flipping.

when he minraises flop then bets big on the turn it seemed a little fishy, someone who minraises i'd expect to continue to bet small on the turn with a set/flush, then again maybe not [img]/images/graemlins/grin.gif[/img]

im close enough to 50/50 against this range:
JJ,66,33,AhQh,AJs,AhTh,Ah9h,Ah8h,Ah7h,Ah6h,KJs,QhJ h,Th9h,9h8h,8h7h,AhQc,AhQd,AhQs,AJo,KJo

is that a reasonable range? add the chance hes bluffing or some more A[img]/images/graemlins/heart.gif[/img] combos, maybe take out KJo.

cheers!
