Craziest hand I've ever played.

[elnino12]

This is by far the most ridiculous thing I've had happen to me in a poker game, but how would you play it?

Pokerstars NLHE $1/2 blinds $200 max buy-in

Hero in MP2 ($245)
BB ($170)
CO ($205)

Hero dealt J [img]/images/graemlins/diamond.gif[/img] J [img]/images/graemlins/club.gif[/img] in MP2, UTG + 1 limps, Hero raises to $8, CO calls, BB calls, UTG + 1 calls

FLOP ($33): J [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/spade.gif[/img] A [img]/images/graemlins/diamond.gif[/img]

BB bets $10, UTG + 1 folds, Hero calls, CO calls

TURN ($63) K [img]/images/graemlins/heart.gif[/img]

BB bets $6, Hero raises to $12, CO calls $12, BB calls

RIVER ($100): Q [img]/images/graemlins/heart.gif[/img]

BB bets $12, Hero goes all-in for $210, CO calls with about $175 left, BB folds.

The more I think about this, the less I like my all-in. How should I have played this, and can you guess what CO held?
