3/6 NL-bottom set, multi-way pot

[tdarko]

both the CO and button are decent players with "some" tricks in their bags, nothing too special though. my image was really laggy at first, i have tightened up the last 2/3 orbits.

stacks:
Hero-790
CO-805
Button-945

i am dealt black 6's i raise it to $20, C0 calls, Button calls.

flop (A [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/club.gif[/img])~69
Hero bets $50, CO calls, Button calls

turn (A [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/club.gif[/img] J [img]/images/graemlins/diamond.gif[/img])~219
Hero checks, CO bets $90, Button raises to $290, Hero???

any thoughts?
