easy fold?

[jonoo]

this is pretty early on in the step higher #2 tourney, not reads on vilian.

Party Poker No-Limit Hold'em Tourney, Big Blind is t30 (10 handed) converter

Button (t795)
SB (t930)
Hero (t975)
UTG (t840)
UTG+1 (t1225)
UTG+2 (t1170)
MP1 (t1235)
MP2 (t970)
MP3 (t875)
CO (t985)

Preflop: Hero is BB with K[img]/images/graemlins/club.gif[/img], 8[img]/images/graemlins/spade.gif[/img].
<font color="#666666">1 fold</font>, UTG+1 calls t30, UTG+2 calls t30, <font color="#666666">4 folds</font>, Button calls t30, SB completes, Hero checks.

Flop: (t150) 2[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/diamond.gif[/img], Q[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, Hero checks, UTG+1 checks, UTG+2 checks, Button checks.

Turn: (t150) Q[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, Hero checks, UTG+1 checks, UTG+2 checks, Button checks.

River: (t150) K[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, <font color="#CC3333">Hero bets t100</font>, UTG+1 folds, UTG+2 folds, <font color="#CC3333">Button raises to t500</font>, SB folds, Hero???

was the river bet terrible? and is this an easy fold in this spot? why would i want to put over half my stack in to most likely at best split 350.
