I think I butchered this hand (KQo)... NL100

[EasyAs1-2-3]

Villain is 25/11/4.5, pretty standard passiveish player. FWIW River AF is 5.5.

Effective stacks 65BB
Hero dealt K[img]/images/graemlins/diamond.gif[/img]Q[img]/images/graemlins/heart.gif[/img]

Villain raises to $4.5 on button, Hero calls from SB

Flop: 9[img]/images/graemlins/heart.gif[/img]Q[img]/images/graemlins/club.gif[/img]J[img]/images/graemlins/club.gif[/img] ($11)
Hero checks, Villain bets $8, Hero calls.

Turn: A[img]/images/graemlins/diamond.gif[/img] ($27)
Hero bets $14.50, villain calls.

River: J[img]/images/graemlins/diamond.gif[/img] ($56)
Hero checks, Villain is all -in for $37.25, Hero folds.

OK - all in all I think this was played terribly. What should we be doing on the turn here? In retrospect I think my weak lead is useless. As played can we call this shove on river and expect to win a decent % of the time?
