Easy Check/Fold?

[Toonces]

20/40 very loose Potawatomi table (this hand being an exception). MP3 is loose and probably a 3-4% PFR. I have the table image of an aggressive pre-flop raiser.

You are MP1 with Q /images/graemlins/club.gifQ /images/graemlins/diamond.gif and open-raise. MP3 reraises you. All fold and you call.

Flop is A /images/graemlins/spade.gif 7 /images/graemlins/spade.gif 2 /images/graemlins/spade.gif.

Do you check/fold?

Would he 3 bet with JJ, 1010, 99, KQs? Seems like check folding might be giving up too easily, although this is a very ugly flop for your hand. Would he lay down KK with no spade if you checkraised the flop and led the turn? I guess this situation is very opponent dependent, but I really dont know the right answer. Im anxious to see what the big dogs think.
