check and let the aggressor bet... the limper either folds or calls, if he calls good... if not oh well. i call the bet and see a turn card... and i hope it's a king, that way i would probably get some good action. I would definitely check raise the turn, my only concern would be a reraise on the turn... from then on out i simply check and call. the preflop raise could have been from kk, though not likely, it does happen sometimes... even a blind squirrel finds a nut every now and then!
