1/2 pocket 4´s would you push this?

1/2 5-max.
Villian is shortstacked and probably pretty fishy, he has 89 dollar preflop.

Hero is in BB and is dealt 4 [img]/images/graemlins/club.gif[/img]4 [img]/images/graemlins/heart.gif[/img]

Preflop: Villian raise to 8 on CO, Hero calls in BB.

Flop: 7 [img]/images/graemlins/club.gif[/img] 5 [img]/images/graemlins/spade.gif[/img] 3 [img]/images/graemlins/spade.gif[/img]
Hero checks, Villian checks.

Turn: 4 [img]/images/graemlins/diamond.gif[/img]
Hero checks, Villian bets 12, Hero makes it 36. Villian calls.

Villian has 46 left. I figure since I raised this turn I have to push river, since I am going to call his push if I check and he pushes.

Anybody like my turn raise? Would you push this river, or c/f, c/c?
