Critique of above
'HERE IS WHAT HE SAYS IN AN EMAIL TO ME. HE SEEMS SO SINCERE...'
Sincerity & fact are different concepts.
'My loss limit for a session is $100-$200 (a second $100 buy max).'
This guy is not a pro. This amount represents less than a green chip pro would play on one round.
'My win goal is (usually) $400 unless I've had several profitable sessions prior. Then I may stretch to $600 max.'
Pro's don't have win limits unless it's heat related, or their wives birthday :)
'I do not push it.'
Push what, oh of course luck. If your relying on luck to win you'll need it!
'I've turned $60 into $600 several times there.'
Why do I get the feeling you've never set foot in a casino. You can see chumps performing this feat every hour at most tables, (you can also see them have equally wide negative swings too. That's what keeps the chumps coming back. I've known decent basic strategy players to play 10hrs a day for weeks & be winning. The house edge is quite small & the fluctuations huge.
'Don't misunderstand me... you can have losing sessions with any system'
True, which is why you can't evaluate any system based on a few sessions like he has done.
'... bad cards, bad players screwing you up, etc.'
etc? bad weather perhaps. Everyone gets their share of good & bad cards. I assume you know to stand on hard 17 & above & DD strategy, so the pro's are making their money with correct strategy on those bad hands, minimising their losses, & betting up when there is an excess of 10's & A's remaining. (That's 5 values 10,J,Q,K,A) offset against 2,3,4,5,6. An Ace Five count is useless against a shoe. It was designed for use against single decks.
'The goal is a winning TRIP.'
It shouldn't be.
'It's easy to get caught up and playing all day, but this almost always results in negative returns.'
You could win 9 out of 10 sessions simply by quitting when you're ahead, or using progressions but your goal should be to maximise winnings. If the game your playing has a positive expectation then this expectation can be quantified as an hourly rate. (approximating this hourly rate requires a computer simulation or a few thousand hours of records) Simply, the more hours you play, the more you can expect to make. Qualification: In order for your results to be statistically valid you need to put in some major hours.
As a BJ pro you would be lucky to make 1% of your turnover, you would expect negative months, even playing full time
Mr ZZyzx has already told you which books to buy. I'd add Blackbelt in BJ as well. This gives you a choice of 3 simple 1 level systems.
Learning to count any of these systems is dead easy. The hard part is putting in the hours, weathering the fluctuations, & avoiding the heat.
If something sounds too good to be true it generally is. BJ is hard work.
Last advice: Don't skimp on the books. They will pay for themselves thousands of times over if you become a pro, & save you hundreds of times over if you decide pro BJ play is too hard.
