Flopped straight...should I have bet this differently?

[Freyjan]

This was only in a 10$, 45 person SnG, so it was a bit of loldonkaments.

Should I have played this hand any differently? Sorry I don't have a hand-history program, I should definitely get one of those...

I was UTG, Villain is on the Button.
Hero stack: 3500
Villain stack: 6100
Average stack sizes at this point in the tourney: about 3600

Only reads I have on him are he likes to donkbet flops a lot, since many of the people will fold to any bets if they've missed anything. Will occasionally bet with air and overvalues draws. Could I have possibly check/folded on this river? First call he made I thought he might have a weak jack...second flat call scared me a bit, but I definitely didn't put him on a backdoor flush.

Might post results after I get some criticism.

Hand: 8d9s
Betting:
1 caller for 100 in MP, Villain calls, Hero calls, BB checks (Pot size: 400)

Flop: 7s, 10d, Jc

Hero bets 350, BB folds, MP folds, Villain calls. (Pot size: 1100)

Turn: 6s

Hero bets 1000, Villain calls. (Pot size: 3100)

River: Ks

Hero all-in, Villain calls. (Pot size: 8200)

You've already put half your stack in the pot on the turn so im not folding on the river i might check call the river though just to try and control the pot size but then again it really depends on what you think hes calling you down with. What does he usually call down with? What does he usually limp with? I think you could see some kind of two pair combo or even maybe a middle set here. He might have also called with a weak jack like you thought and backed into a flush, i dont think thats very likely though. I think i check call the river here though.

He would generally limp with unsuited connectors, or mostly any face card with a not completely horrible kicker (A8, K9, QT are a few that come to mind). He also raised the button often, which is part of the reason I couldn't put him on much here, as he just limped along.

I was thinking about the check/call line here as well, but I figured I was committed and knew he would just flat call (or put me in if I hadn't bet) anyway, so I just opted for the shove of the rest of my stack.

Thanks for your input, any other takers?
