Tournament Strategies
After receiving pocket cards, you are immediately faced with a choice: play your cards and either raise or call the blinds, or fold.
Practice Matters
If your opponent doesn't react well
If your opponent doesn't react well to aggression, then donking into them with your air range that has over cards, gutshots, and sets can be a good line. You're not going to flop a set often, and when you do, they usually won't expect you to lead into them until they've seen you do it. If they have a hand, they're going to call or even raise. You just have to make sure that if you're consistently donking into them, that when you do have a set you lead into them as well. Mix in doing it with top pair occasionally as well.
If your opponent is aggressive and tricky
If your opponent is aggressive and tricky then check/calling and leading the turn, or check-raising with gutshots and sets can be effective. Note that, again, because of hand distribution it wouldn't be very balanced to check-raise with over cards and sets since most of the time you'll have over cards. Your opponent still will be able to weight your range well enough to make good decisions. It's still more effective to have a hand in your range versus not having it at all, but the frequency of distribution of the hands you do something with is nearly as important as the range itself.
