Poorly played $5/10 hand

[Malone Brown]

CO is a 2+2er who is LAG, I respect his game. Not been getting hands this session, CO's been pressuring me alot, probably sees me as being pretty tight.

Ultimate Bet No-Limit Hold'em, $10 BB (6 handed) converter

Button ($485)
SB ($582.50)
BB ($968)
Hero ($1151)
MP ($360.50)
CO ($1632)

Preflop: Hero is UTG with K[img]/images/graemlins/heart.gif[/img], J[img]/images/graemlins/heart.gif[/img].
Hero calls $10, <font color="#666666">1 fold</font>, <font color="#CC3333">CO raises to $45</font>, <font color="#666666">3 folds</font>, Hero calls $35.

Flop: ($105) 9[img]/images/graemlins/spade.gif[/img], 3[img]/images/graemlins/heart.gif[/img], 5[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, CO checks.

Turn: ($105) A[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">CO bets $65</font>, <font color="#CC3333">Hero raises to $145</font>, CO calls $80.

River: ($395) 5[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">CO bets $1442 (All-In)</font>, Hero ?.

checked river knowing CO would take a shot at it, wasn't prepared for the all-in though....where'd I play it wrong and who calls here???

Thanks
