$6 Turbo NLHTRN Should I Valuebet on River

[CASHius-Clay]

Late in a $6.00 SNG at FTP (Turbo) I have been shortstacked after a bad call (down to 450) and was getting back to 1395$ especially because of agressive play and stealing the blinds and c/betting on the flop.

Villain played very tight and never called a minbet on the flop if he had not hit the flop in any ways.

I played very agressive because the blinds were quite high. Then teh following hand.

BB <font color="#A500AF">(villain)</font> (t1605)
Hero (t1395)

BB <font color="#A500AF">(villain)</font> calls t60, Hero checks.

Flop: (t300) 9[img]/images/graemlins/diamond.gif[/img], 7[img]/images/graemlins/spade.gif[/img], 2[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>

Turn: (t780) 8[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets t120</font>, villain calls t120.

River: (t1020) 3[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets t915 (All-In)</font>, villain folds.

Final Pot: t1935

Him betting out at the flop and calling my bet on the turn told me that he had hit the flop. (Maybe top pait or midpair, even bottompair would be possible)

Should I just have Vlauebet after the River or was my shove ok?
