Trying too hard on the river?

[Big Dave D]

Party Poker (7 handed) 5-10 blinds

Preflop: Hero is MP2 with 5[img]/images/graemlins/club.gif[/img], 4[img]/images/graemlins/club.gif[/img].
<font color="#666666">5 folds</font>. I call in early middle and Villain raises it 25 and I call. Villan is unknown, 24/5 PT stat after 50 hands, which doesnt mean much. He has 1k and I have him covered.

Flop: 5[img]/images/graemlins/heart.gif[/img], 6[img]/images/graemlins/club.gif[/img], 9[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks. Villain bets half the pot and I call.

Turn: T[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, Villain checks. Obviously I was going for a check raise here [img]/images/graemlins/frown.gif[/img]

River: 8[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
I bet 125 into a 175 pot. Villan raises to 300 striaght leaving himself 650.

I moved all-in. Insane?
