There are some tactics that you can "steal" from professionals, which can give you a huge advantage against the remaining players.
If you are planning on starting stud poker, you should really work on your ability to follow discarded cards, as they may be a game-changer.
As stud poker variants feature cards that are dealt face-up, you should memorize them and evaluate not only the potential of your hand but also the others.
Just to support those statements, let's say you have a straight draw, and you only need a 10 to make it. But, if all of the 10s were discarded, you can fold and not put any more bets, as your straight draw will not become straight.
On the other hand, if a remaining player tries to bluff, by representing a certain hand, you can easily read it. Let's again face a straight-draw example. If your opponent bluffs for a straight, the needed card is 8, and you have it in your hand. You will be able to win the pot if you followed the rounds and memorized that all the other 8s were discarded.
Similar to knowing how to read the discarded cards, you may also take advantage if you develop your skills by evaluating what your opponent is waiting for if he has a straight draw or a flush draw.
How other players act
This is one of the most important factors that separate professional poker players from beginners and applies to any type of poker, no matter if it is a seven-card stud, five-card stud, Omaha, or Texas hold'em. You must pay attention to what other players are doing, and how they act, even if you are folded in a certain hand.
Nowadays, reading others has become a little bit harder, with the era of online poker. However, you can still benefit from developing your reading abilities.
For example, you can determine if your opponent is bluffing or not, just by seeing how fast he is betting, and how much he is betting. Pretty much every signal can be beneficial for you, but you need to learn how to spot any of them.
