DoN bankroll management

From what ive observed people normally play with 80-100 buyins for cashgames...what about sitngo?

Does making the step from $1.10 DoN (because of rake) to $5.20 require that I have a substantial bankroll of 300-500?

Currently I have about ~$100+ built up, any of you out there play $5 DoN with this size bankroll?

Re: DoN bankroll management

It's very standard to have a 20-25BI for cash games, not the 80-100 you're talking about.

For 9 man SnG's I belive it's fairly standard to have a 40-60 BI level.

Due to DoNs having less variance... and being so damn soft at lower levels, you could easily get by with a 20-30BI BR.

Depends on what kind of risk you're willing to take. Earlier this year I decided to play a bunch of these things to clear a bonus and after a couple of hundred games I wrote a quick and dirty simulator to try to get a feel for what I was in for (and for fun). I used to play around with this thing a lot.

You need AHK if you want to run it.

The defaults are set to simulate 100 players with 55% ITM playing 1000 of the 1.10 games, starting with a bankroll of 50 buyins. 55% ITM is breakeven for the 1.10s.

If you change it to 20 buying at the 5.20s, you'll see that between 5 and 10 of the 100 players go broke at 55% ITM. Increasing the bankroll to 30 greatly reduces the chance of going broke (as does increasing the ITM, obviously).

Also note that the program assumes that each player continues to play at the given stakes no matter how small or large his bankroll gets. This wouldn't normally happen in real life.

Re: DoN bankroll management

I play only DoNs and in December I had a downswing of 28 buyins and had to rebuy since i was down to 12 (i play with 40 buyins) and didnt want to go to a lower level. I am at 57% ROI and no, I am NOT the sharkscope 1MillionChip... that nick is taken by someone else :/
