I assume Villain raised enough to commit himself to the pot in both cases? You say he'd been open raising a lot, but how often did he re-raise? If he was often raising vs. limpers and coming over the top of raisers, then every time you are going to play a hand, you need to decide whether you are willing to go all the way against him with it, and if so, you need to structure the betting so that you are the one putting in the last (pot-committing) raise. So if you expect that he will raise if you limp in the SB and re-raise if you raise, you should do whatever will allow you to be the one to put all of his chips in the middle first. This may mean limp-re-raising. With a hand like KQs, it isn't the end of the world if Villain checks, as it plays well post-flop. Pretty much the same thoughts on QJs, although, you might also choose to limp, call a raise, and push or check-push any flop that gives you a draw or a pair.
