Help settle a debate: this guy's bluff good or bad?

[Taylor Caby]

i actually kinda like this, but you didn't tell us what his image is. assuming it's fine, i like it. you probably don't have a straight, and making this call is going to be throwing away money against a tight player without a straight.

calling totally depends on his image. basically, "is he capable of making a play here and what is my image" give you the answer of if you should call.

10/20 NL. I've been aggressive preflop but not out of line and haven't been caught doing crazy [censored] yet, but definitely reraising more than most.

Anyway, villain raises to 70 on the CO, I make it 250 w/xx from SB, he calls with TT.

Flop(510): 5 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/spade.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img]
I bet 300, he calls
Turn (1110): J [img]/images/graemlins/club.gif[/img]
I check, he checks.
River (1110): 9 [img]/images/graemlins/heart.gif[/img]
I bet 760, he insta jams for 900 more. Anyone like this push by him?

Also, if you're in my shoes and there are no real reads either way what's your minimum hand to bet this river with?
