I think SNG are the best way to go . You can learn to become tight and learn to play tournments at the same time. Once you get good at SNG and build your
bankroll up a good bit you can switch over to MTT or cash games if you like. by that time comes you'll have a good unstanding of how to play the game as far as hand range and position go's you'll just have to learn some of the other concepts like 3 and 4 betting and stop and go's which you can do actally in SNG's as well but don't get to tricky while paly SNG's you want to play them kind of straight up and forward. But build in more concept as you move up from level to level till you get up to the $109 level were the pro play that were you'll find all the tricks and plays being done. By then you better be ready to have all your eggs in your basket or you'll get ran over.
