Ouch !!!

Played the $50 2:00 p.m. on party, was doing fairly well until i got stinged with this hand when this luckbox sucked out on me on the river.
Thats pretty much the kind of week I had.

Blinds 200/400 I have $3680 and am 2 off the button.

A short stack from goes all in for $1555.
I smooth call, then the BB who has been overplaying alot of hands raises to put me all in.
I am pot commited here so I call.

Turn over our cards:
Me: JcJd
Initial raiser: Ac 8s
BB: 4s 4d

** Dealing Flop ** [ Ks, 7d, 5h ]
** Dealing Turn ** [ 9h ]
** Dealing River ** [ 4c ] Bye bye me !!!

20 from the money.

Is this the cashout curse??? Will wait and see...
