What I call an advantage in learning holdem is having some skill at other poker games
and using those skills. I think the all around best game is seven card stud high poker. The reading skills, the ability to deduce the holdings of another player will ground you with enough skill to make you skillful in any other game as well. A lot of players think that luck rules with seven card games, but believe me, it takes skill to win this game in the long run. Just a tip, don't ignore other games.
