I got two questions here..
#1) what the most profitable room to play in on internet poker (such as NL, fixed limit, or sng's)?
#2) Do bad streaks happen often and how bad to they usually get(have the big players in here lost alot of money in one day becuase of numerous bad beats)?

the bad streak relates today where i got NO hands all day only made a couple of dollars, and when my aa came it was busted along with my kk and along with my set of twos and there was MORE..

I played the KK prefectectly too...traped a guy with 1010(i had him on jj,,, close enough) and put him all in, river came 10. I dont' believe i'm playing badly. i can't make any profit i always end up even

I dug up my copy of Poker essays, since I can't remember where I put "Gambling Theory". In it Malmuth uses a simple formula to calculate your absolute BankRoll (BR) required for a given Win Rate (WR) and Standard Deviation (SD, a measure of short term luck found by taking the SqrRt of your variance, which is found by averaging and then some of your past results).

The forumula is thus: BR = (9 SD^2)/(4 WR)

In my experience, and from PT data, most winnign players have around a 3 bb/100 (generalized) WR, and a SD of about 20 bb/100 (again, generalized). SO If we plug in the numbers...

BR = (9 x 20^2) / (4 x 3) = (9x 400) / 12 = 300 bb

This tells us, if you play your normal game, this is the theoretical worst that you can do. Meaning you can lose 300 bb before you even post a winning session.

Thats the short version of about 50 pages in His books, there are quite a few little If's there, and even he admits this is just an approximation of reality.

Here's a quote that always helps me through bad beats:

"You have it in your power to turn a bad-beat around simply by realizing this simple truth: The more bad beats you encounter, the luckier you are. It's a sign that you are playing against opponents who continually take the worst of it, and if you can't beat someone who always takes the worst of it, you can't beat anyone." -Lou Krieger
