"Because I usually play smaller stakes"
If you are beating smaller stakes games that has a rake on them, you are one of the few.
Expected win in $2 & $4 is minus for the year with a $3 rake and $1 jackpot drop.
$4 and $8 with $3 rake and $1 jackpot drop has a small expected win based on yearly win. I know people that do $4000-$6000 on it.
The above is based on playing 6 days a week and 4 to 6 hours a day.
$4 and $8 with $4 rake and $1 jackpot drop is about even.

Here is my story.
I started playing in 1961-2 with the illegal club operators in Newport, Ky that Bobby Kennedy put out of business. Mostly pot limit. Martin Miller, owner of the Merchants Club took a liking to me. He told me "boy you better learn what they are doing to you in the games you play."
He taught well. He taught me to gambol with an edge. He taught me to watch the game until I saw what, and who was doing what to whom. Once you learnd their edge it was easy to play back over the top of them. I traveled a circuit from Atlanta to Erie, PA playing poker.

He taught me to bet horses with an edge. We once made 32 straight bets on the winners at River Downs over one season. It was the only 32 bets we made that year. We did not make one bet the year after that as the edge we had was gone. I have never made a horse bet since that year.

He taught me to NEVER make a sports bet. I never have.
He taught me to lose at pool to the right person at the right time. His name wound up being "The Mark" after he beat me.

I made a good living from poker and other gambling for 19 years. Put 2 girls through college on the profits. I moved to LV in 1980 and got the first real job I ever had.

The rest of the story is LV. Its been a good life.

The moral is if you don't have an edge, you fly with the other "geese!!!"
