The lite version allows you to configure payoff tables and create a single strategy chart for any game you input. You can also use the lite software to practice playing the various games. It lacks some of the other fancier features, but those are a bit “fluffy” anyway. You can download free demos from the site before making a decision as to whether or not it’s a good purchase for you.
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.
