A straight is a hand with consecutive ranks, like 9? 7? 10? 8? 6?. Notice again that the cards don't have to appear in order. The order of face cards, from lowest to highest, is Jack, Queen, King, Ace, which we abbreviate J, Q, K, A. An ace can also count as 1, to complete a straight where the other cards are 2, 3, 4, and 5. But it can't count as both a low and a high card, e.g., Q K A 2 3.
That's a pretty lengthy list for a beginner, but it can be shortened considerably by taking all those three card straight flushes -- open, inside, double inside, with high cards, without high cards -- and lumping them together just below four high cards. That'll cost you a few tenths of a percent, but when you're comfortable with the rest of the strategy, you can start breaking down the categories for more expert play.
It contained the games that I was specifically looking for, which were Jacks or Better and Deuces Wild; but also contains a total of 23 different poker games - some of which I hadn't played before, but will play in the future after trying them out on WinPoker. I believe that it does have the majority of games included that you see at casinos: Bonus Poker, Double Bonus Poker, etc.
