Expert Strategy consists of three key components - (1) Know which games to play, (2) know the right strategy for those games and (3) know what to expect.   I find the third one to be the most intriguing.  When it comes to video poker, I realize I'm hardly the only source for video poker information.  There are other writers and there is a variety of practice software out there.  These will all help you to learn the first two.  But, I think it is a combination of my math skill and the ability to explain it to the masses that help to separate me from some of these other sources.  One doesn't really need to know what to expect in order to master the first two, but learning it is what keeps the Player disciplined to stick to the plan.
