how much maximum bet do i need to raise my money is $500 in one session.anybody can help me appreciated.
Honestly, you may not like this answer...
Bet 1/3 of your stack and continue to bet 1/3 of your stack until you have $2,000, then bet 1/5 of your stack until you have $4,000, then bet 1/10 of your stack until you have $6,000 then bet 1/20 of your stack until you have $10,000. Then size to full kelly from that point out until your bankroll is about $30,000 then begin gradually reducing your risk as your bankroll continues to grow from growth phase to income producing phase.
Normal measures of risk are a waste of time when the bankroll is tiny and easily replaced. When the bankroll is tiny variance is your friend...you either get a useable bankroll quickly or bust out quickly and move onto other more profitable and productive things.
The other option is to find a game other than blackjack that has a much higher advantage...or scrimp and save until you have $5,000 and can try a more realistic "Hail Mary" approach. A $500 bankroll is really useless for blackjack unless your goal is to play a $5-$15 break-even type game on low limit tables and get lots of free drinks...then it's a great entertainment value....especially at full tables.
