6. Pair of jacks or better. Discard the remaining three cards. Sometimes players who are used to playing table poker want to keep a high-card "kicker" to the pair -- for example, holding an ace along with two queens. Don't hold a kicker in video poker; give yourself the maximum chance to draw a third high card, or even a full house or four of a kind.
I am spending time on this topic for a very good reason. Open straights and straight flushes are always listed higher in a strategy chart because they can be filled in more ways than an inside straight / straight flush. Therefore it is important that you know the difference when you play so you do not inadvertently consider an inside straight / straight flush as though it was open.
An inside straight is a would-be straight with a hole in the middle. 9? 2? 10? 8? 6? is an inside straight because only a 7 will turn it into a straight. The distinction between outside straights and inside straights is important because in Jacks or Better we will never try to turn an inside straight into a straight. It's too hard, since we have only one chance of completing the straight.
Two major factors determine the characteristics of a video poker game. They are the payback, which can also be stated as return or calculated from the house edge, and the variance or volatility. We examined how payback (or return) and house edge are inter-related in the last section. In this section we will look at the other half of what defines a video poker game – variance or volatility.
