In low limit poker, a primary mission is to overcome the rake. It's extremely hard to beat the rake. Many I know doubt 7% of all 1/2NL players avg $14 an hr. The rest are lose long-term.
If you get 25 hands an hr & avg rake is $4 & avg tip is $1, which is extremely conservative, that's $125 going off the table. Plus the $18 per hr you want to win, means
everyone else has to lose a total of $143.00 per hour, in order for you to win $18 an hour. If someone else is also winning, that total is even higher.
That's why table selection is paramount in winning long-term.
There's $11 [after the rake] going into the Flop.
If you bet $10 & all 5 call, there's $71 - $6 more in rake/BBJ = $65.00
If they are calling $10, then they are calling $11.00.
$11 * 6 = $66 + $11 = $77 = $70. Now you have an extra $5 of their $$ in the pot. That $5 adds up over the year when you play ~100 hrs a month.
You got 2 callers. Do you think 1 might have folded if you made it $11?
$11 * 3 + $11 pre [after $1 rake] = $44.00. You're still between $40 & $50, so you got $2 more on your opponents' $$ in the pot without any additional rake.
I don't even tip the dealer from my stack. So of course I don't tip the waitress from it.
If I have a session where I go up, then down some, then up some then down some, etc. & find myself sitting on $425, but have won 10 pots that warranted tipping the dealer a $1, and tip from my stack, I'm sitting on $415.00
Now I get it all-in vs. a player who has me covered & win. Problem is, I only have $415 instead of $425 [when tipping from my stack] &
NOW tipping the dealer has cost me $20 instead of of $10.00
Not really, because I don't win 100% of the time. However, if I have 60% equity when I GII,
in reality, I lose $6 in potential long-term profit.
My session logger tracks tips & then at the end of session I can change buy-in amount to $300 [or $500 in 1/3] + total tips, in order to correct my net profit.
