Does anyone here know anything about the strategy of playing video poker? Specifically, I would like to know the following: 1. In playing Jacks or Better, is it advisable to hold a small pair (10's or less) instead of a jack or higher you are holding? 2. How many different face cards should you hold (assuming that a straight or a flush are not one card away)? 3. Is doubling down a good bet? If so, how many times should you do it on any one hand?
