Live 5/10 NL out of position, top pair, facing heat

[tdarko]

the villain is an aggressive chinese kid i stacked earlier but since has rebuilt nicely. he is very aggressive with or w/o a hand. doesn't really set traps.

stacks:

Hero-2850
Villain-2200

the entire table limps to me in the BB and i make it $80 with A [img]/images/graemlins/club.gif[/img]K [img]/images/graemlins/club.gif[/img], everyone folds to CO who calls, rest fold.

flop K [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/spade.gif[/img] pot ~$240
Hero checks, Villain bets $200, Hero calls.

turn K [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/spade.gif[/img] pot~$640
Hero bets $400, Villain raises all-in $1920, Hero???

comments on all streets please.
