I agree with Renton that flatting this flop is the best (I would jam sometimes if there was a FD out or something). I think raising small could also be ok, if villain is the type to spazz... raising him 20 to 42 or something.

Though I certainly don't think anyone will ever in their right mind fold KK or AA here! I've definitely seen ppl in hero's spot shoving A7ss, 88+ to not warrant making any big folds here.
