Razz poker is of course more algorithmic than draw games. This is not to say that draw games are not a complex game, but betting in Razz poker demands a high level of skill for the low hand, and the cards in Razz are very exposed and most of the information is out and it's merely an acknowledgement that it is easier to develop effective strategic generalizations in Razz poker and the table will be more competitive.  It is also says nothing about the predictability of Razz poker, because playing world-class Razz poker of any limit is a task of another order of magnitude. None of the players will know the optimal strategy is for no limit Razz games, and it literally does not exist either.

Never play low variance games where you are depending on the impact of luck in winning in Razz poker. For example, you might fold a hand that someone is calling realizing the danger in where in the final street the other guy got an Ace; however, you might not know if you were waiting for the Ace too, if you would get it done in your board in the next draw if there is yet another draw.  Early folds have some regrets in Razz poker also, but this is quite common. Forget it, if you did fold one hand with a 50% heart.

Some see Razz poker as the way of the future, they think it reduces the luck element because the winning requires just worse cards; the balance between luck and skill in poker is the same in every variant of poker!

Aggression works in Razz poker too because it can win money by forcing an opponent to fold a better hand it can prevent your opponent hand by folding an hand that will improve or you win more because when you have a good hand and you get called. Either way aggression should be done in the right situation.  You need to know what card the opponent is chasing for making sure that you do not reveal what you are chasing for. If you are going to go aggressive against a potent winner, they are going to do nothing but call and eventually they are playing you make more money.  Before you go aggressive, look about against whom you are betting and be sure that aggression will not make the situation worse for you personally.
