-What are the odds of me hitting...
Based on the probability of how many ways particular hands that can be dealt at a table with seven cards from a 52 card deck, the way that you want to play your combinations is to achieve the higher ranking hands where probabilities aren't out of the range of 'realistic'. You also don't want to be playing hands that are far too common and can be easily beaten.
|Four of a Kind||224,848|
|Three of a Kind||6,461,620|
Looking down the chart which is arranged from the highest possible made hand to the lowest hand, you see that there is a large mathematical leap between ways that a four-of-a kind hand and a full house can be dealt with seven cards. The range of realistically catching better than a full house comes to a screeching halt. There is another large gap between three-of-a-kind and two pair.
The starting hand combination strategy used for winning seven card stud hands, promotes aspiring to achieve the median; three of a kind or better. The odds of catching the median hands differ depending on how many players are at a table, how many players continue on to later betting rounds, and the type of hands that any player at a table is striving to achieve.
In my experience at fully seated low-stakes tables, it is not uncommon that players are using combinations that will make two pair or better. When playing for two pair, naturally you will want to have the highest two pair, and strategy is adjusted accordingly.
The table below shows odds for flushes and straights. You can determine your odds based on the number of persons in a multi-way pot. For example, if you have one card to draw to a flush, your best odds to catch your flush is to have 4-5 people calling bets. Straights happen most often at stud hi/low tables because there are so many people in the hand at a time, more closely matching the odds needed to catch that particular hand.
