My attention was recently drawn because my skeptical comments on BJ21 about a self-proclaimed pro generated a multipage locked thread here. FWIW, I am a professor who worked on Wall Street, did the optimal departure analysis for Don Schlesinger's Blackjack Attack, coauthored poker books Kill Phil and Kill Everyone, and published research about sports and point spreads.
Here are my suggested topics:
Gambling Frauds (Ask and I'll evaluate them),
The Myth of Professional Card Counting,
The Most Common Counting Mistake (Playing while losing),
The Biggest Counting Mistake (Underbetting),
The Typical Wrong Way and the Right Way to Visit Vegas,
Comparing Counting to Poker, Sports, and other advantage play.
Of course I'm happy to address any mathematical topic, including:
the OPP/Speed Count,
the best single parameter Adjusted KO count {-.5,.5,1,1,1.5,1,.5,0,0,-1},
shuffle-tracking with unbalanced counts,
optimal departure,
Kill Phil poker analyses,
How math and statistics can inform you about playing, bankroll, comps, risk, expenses,
optimal spreading,
certainty equivalent,
getting comp value.
The math questions might be better addressed in forums. If you post questions here then I'll mull them over, and you might get some like-minded to ask helpful follow-ups.
