Flopped Two Pair Seems Okay...

[BoxTree]

Commerce 3/5 (200-max)

Hero stack: ~$400
Villain stack: ~$400

Hero in the BB: A[img]/images/graemlins/heart.gif[/img] 2[img]/images/graemlins/heart.gif[/img]

Preflop (7 players): Call, call, fold, fold, call, complete, Hero checks.

Flop (5 players, $25): A[img]/images/graemlins/diamond.gif[/img] 2[img]/images/graemlins/club.gif[/img] 7[img]/images/graemlins/diamond.gif[/img]
Check, Hero bets $25, Call, Fold, Fold, Fold.

Turn (2 players, $75): 8[img]/images/graemlins/heart.gif[/img]
Hero bets $75, Villain calls.

River (2 players, $225): J[img]/images/graemlins/spade.gif[/img]
Hero checks, Villain is all-in (~$300), Hero...?

Notes on Villain: Sees ~80% of flops, but gets away from most of them unless the flop hits him pretty hard.

I'm not convinced that betting out on the river avoids this situation. If I make any reasonable bet and he calls, maybe I win, maybe I don't. If he raises me, I'm getting filthy odds to call his raise. Maybe I can bet ~$125 and fold to an all-in?

Questions: Do you bet out on the river? Do you call his all-in? Is this so heavily read-dependent that your comments and my questions are in vain?
