10/20 J8s flush draw hand

[tomahawk]

No good limit games going, so I decide to play a little NL. I may have chosen a limit a bit too high for my standards, but what the hell i figure..

Full Table. MP1 ups it to 60, two people call and I call on the button with J [img]/images/graemlins/spade.gif[/img]8 [img]/images/graemlins/spade.gif[/img]. BB calls too.

5 to the flop of 6 [img]/images/graemlins/spade.gif[/img] 7 [img]/images/graemlins/spade.gif[/img] J [img]/images/graemlins/diamond.gif[/img]

Checked to me, I bet 200 into a ~300$ pot. Folded to villain to my right, who checkraises to 800. I started the hand with 2100 and he has me covered. I haven't got much of a read, but no reason at all to think that he is fooling around.

My action?
