Last night, I won $3K playing blackjack. What were the chances of that happening?

I bought in to the $25 minimum bet table with $300. I started betting $50, increasing my wager by $25 each time I would win a hand. At one point, I won 12 hands in a row, however I stopped increasing my bet when it reached $300. I ended up cashing out when I was ahead $3K. I was actually up more than that but I lost a few hands betting $300.

What I really want to know is what were the chances of that happening, mathematically? I never expect to win anything at a blackjack table, but I walked away a big winner there.
Mr. Ed:

One other person was at the table. We were both playing basic strategy. DAS allowed. Dealer stand on soft 17. Six deck shoe. Don’t know the penetration, I was too caught up in the moment.

 
 

Blackjack as a career: Can playing it online once a day then cashing out increase your chances of winning?

In terms of online blackjack… if you wanted to make a career out of winning it, be it $1000 a week, if you just bet $200 and played it ONCE a day for only FIVE days a week, then cashout and start a new the next week, would the odds more likely be in your favor as opposed to playing it continuously in the same day?

Or not even $200 a day, how about betting $10 an hour for eight hours a day, 40 hours a week, heck maybe 20 hours a week just for some extra cash. Would this be any better in terms of odds?

I think you know what I’m getting it here. See I think these online casinos have something programmed to make you lose after you’ve won a few times, cuz if you win once, you’ll play again and win, play once more and win, keep playing and then start losing. But what if you just play once a day for a certain amount, cashing out immediately after and repeating the next day?

 
 

Does the presence of inexperienced blackjack players at your table really decrease your chances of winning?

Which player would win more:

A player who plays a million hands of blackjack by the book at a table by himself

OR

A player who plays a million hands of blackjack by the book at a table with an inexperienced player who does not play by the book?

Assume an eight deck shoe that shuffles after six decks.
