buying in for 200 bb's can be better than playing at a higher level.

the blinds are the same at 5NL whether you buy in normal or deep. but, the potential gain and loss is greater. as a deep stack, you have the power to push shorter players AI quicker. there is a "mental edge," imo. you can look like you have nothing to lose. thus, another player may not push YOU in because he thinks you will call him.

playing 200 deep instead of moving up can also be nearly as profitable. the players' skills are worse at 5NL than at 10NL, theoretically. therefore, you get more money on the table with a skill advantage, and thats rarely a bad thing.

by moving up, you may also be playing more timidly. by putting 200 bb's on the table, at your comfortable level, you may avoid said timidity.

and, btw, why do they play 700 bb's deep on HSP instead of simply raising the blinds to $2500/$5000?

care to share your "cons." i'm not being a dick, i just want to see a little more detail on your "argument."
