In addition to what Al said, you need to adjust to the play of the people around you. I find that there are always a couple of people at the table that tighten up a lot in kill pots (they don't want to risk the extra money) so you can be more aggressive and push them off hands. There's also usually one or two people who become more aggressive in kill pots, probably recognizing the weak-tightness in the first group. Just play your regular game and make adjustments when you see how your opponents play.
