There is no specific tournament strategy for stud. Whether you play stud, omaha, hold'em, or even draw, the real game is still tournament poker (playing your stack, bubble play, final table play etc.)
For cash games, the best beginner book imo is Roy West's book on stud, which is also a very funny and entertaining read ("If you haven't understood that by now, you are either not paying attention or you are a hopeless dolt intent upon giving away your vast fortune so that your kids won't get their hands on it"
)
Once you master the concepts in that book, read 7CS4AP (and study it) The Chip Reese chapter in SSI is good too
Whereas hold'em (and even games like five card draw) has become extremely tough to beat online now, even at the lowest levels, the opposition at low limit stud online is still ridiculously weak. Almost every table has a few players playing almost every hand on 3rd, chasing everything, not knowing what to do, they just literally want to give you their money, at times, it's just unreal.
Apparently many people just play and don't want to bother learning to play 7CS well and studying it because it is a more complex game than hold'em and takes a lot more effort and time/experience to play it well. If you study the game, you will definitely have an edge over the field and know more about the game than your opponents do
