played only 14 hands or something with him. he seems loose passive.

fuck, wrong forum sorry

No way he's folding, a loose passive will put you on exactly what you have and call a bluff here with a jack. It seems pretty unlikely he's called you down with the naked Qd. I don't think the second barrel is a good idea either. He's usually always going to call that turn if he calls the flop.

he have a pair here almost always and will never fold after calling flop and turn

Vs an unknown with 14 hands, I hate making bluffs like this.

If he's loose passive, I'd check it down and take a note on his hand and how he plays it.

just check / fold, hes not folding

betting 70 has to work a little under 50% of the time but checking loses this pot like 95% of the time
14 hands and you are saying he SEEMS loose passive, how acehud-oriented can you get?
bet the river or don't bet the turn

If i'm going to fire this turn I'm going to be firing this river very very often. I'd prolly shove river to make a call harder too.

i dont shove this river often vs a decent player but he seemed loose passive (now ive played a couple hundred hands with him i know for sure; its the 50/20/1.2 type. i figured he would float lots of diamonds once or twice and all jacks and might fold some weaker jacks (i was hoping he would even fold AJ) so i thought shoving this river might be profitable.
