10. Low pair (two 10s or lower). Most new players keep a single jack or better rather than a low pair, and it's true that keeping that one high card will result in more frequent winning hands. But most of those will be 1-for-1 payoffs for a pair of jacks or better. Keeping the low pair will result in more two-pair, three-of-a-kind, full-house, even four-of-a-kind hands.
But that is where the similarity with random slot machine play ends. The video poker player has total control over the initial five cards that have been dealt. It is his or her choice what to do with those five cards. The decisions about whether to keep all of them, discard all of them, or anything in between is totally theirs. It is actually totally yours. After all, you are the one reading and learning from this guide.
In the right circumstances, however, the player sometimes will break up a flush, a straight, or a pair of jacks or better. If you do not have one of the "always keep" hands, use the following list. Possible predraw hands are listed in order. Find the highest listing that fits your predraw hand, and discard any cards that do not fit the hand. For example, if your hand includes jack of spades, jack of diamonds, 10 of diamonds, 9 of diamonds, and 8 of diamonds, you have four cards to an open straight flush in diamonds, and you also have a pair of jacks or better. The four-card open straight flush is higher on the list than the pair of jacks or better, so you would discard the jack of spades and draw to the four-card straight flush. You are giving up the certain 1-for-1 payoff for a pair of jacks, but you have a chance at a straight flush with either a queen or 7 of diamonds, could draw a flush with any other diamond, or still could finish with a pair of jacks by drawing the jack of either clubs or hearts.
Despite the importance of finding the best machines, most players don't. That's why casinos can offer both decent and lousy machines in the same casino and be confident that gamers will still play the lousy ones. They have to keep some good machines, otherwise they'd lose all the players who know what they're doing. But most of the machines will be bad, and most gamers will play them anyway. Heck, in Vegas even casinos and supermarkets have video poker, with absolutely terrible paytables, but people will still play them rather than going across the street to a casino where they can get seven times better odds. Go figure.
