There are two main thoughts present here, money management of the br as well as types of gameplay.

Through experience I have found one of the easiest ways to build your br is to start with a double or nothing format. Dub's are fairly easy to place in as one only needs to beat half the crowd. Carbon has 6 and 10 player games starting at $1.08, $2.16, $3.24 for 10 ppl and $2.16, $3.24 for 6 ppl. The objective is now to stay alive through half the crowd, hence tight and selective. Try to avoid Turbo's so you can be choosy with hand selection with much time before blind problems. Be willing to throw away mediocre calls with the focus on survival and you should be able to get paid.

As to br management, I am somewhat ingraded to the portfolio management theory of no more risk than 1/20 or 5% of your roll on any proposition. However when considering the type of game one is playing and then factoring in the liklihood of placement I tend to gravitate to 10% for dub's. Outliving 3 or 5 people in a dub is a higher probability that placing in 10+ person SNG's. If the crowd is significant than minimal should be risked as the payout is of much greater mutiples.
