i think noobies like myself should stick with 100 bb poker. I think shortstacking anywhere between 20-50 bb is probably pretty easy up to some level. I don't know the exact treshold but i think the finesses that come with profitable shortstacking are underestimated. Most people look down upon shortstacking and say things like ' anyone can shortstack ' . I don't agree, being really good at shortstacking requires studying situations just as much as 'normal' 100 bb pokersituations in general. That being said i think it's better to start off playing 100 bb poker to really get decent fundamentals on the game. You'll get better at assesing ranges , strategy and tactics. I also believe that anywhere below 50nl maybe 100nl you are better of playing 100 bb in terms of profitability. There are enough weak players to exploit for 100 bb. Rather want to exploit people for 100 bb than for 20-50 bb.
