25/50 blind battle spot - standard fold?

[Dale Dough]

I'm shortstacking the game because I've ran out of funds on this particular site (again [img]/images/graemlins/frown.gif[/img]). Anyway, effective stacks 4k, and no particular read on Villain, as I'm new to the site, but he has an 18k stack fwiw.

5 handed, folded to SB who makes it 170. I call in BB with A[img]/images/graemlins/heart.gif[/img]J[img]/images/graemlins/club.gif[/img].

Flop Q[img]/images/graemlins/heart.gif[/img]J[img]/images/graemlins/heart.gif[/img]2[img]/images/graemlins/spade.gif[/img]
Pot 340

He bets 300, I call.

Turn Q[img]/images/graemlins/spade.gif[/img]
Pot 950

He bets 900 I call

River 3[img]/images/graemlins/heart.gif[/img]
Pot 2750

He shoves, pretty much exactly one PSB to me.

I fold, pretty sure you are never getting bluffed here as an unknown

Raise pf (you've got position and a hand that definately should be raised).. Sometimes I raise the flop if I know how to respond to shoves/calls but without a read calling is better. Calling the Turn is standard, could make an argument for raising with a certain image if you expect him to call you with worse jacks but the solid line is to call again. River is a very dirty card. He could always have QX, 22, KK-AA or the flush (also a dozen bluffs). Without a read this is a clear fold.
Keep in mind this hand is very very opponent/read dependant so with the stuff you provided here there isn't much we can work with.

i think preflop is fine, i think turn is a easy shove tho. good luck
