Though with a very small sample, I was able to replicate in Shreveport a couple of days ago what I had done with an online blackjack small sample: correctly predicting an Ace about 5 times out of 34 attempts. If I am not mistaken, I believe this equates roughly to a 6% advantage.
My next step is to actually try to make some money doing this. With an extremely limited bankroll, my thought has been to 'meet up' with a high roller in Vegas who would be willing to watch me play for a few hours risk free while I surreptitiously indicate to her/him on which hands I think we have that 6% advantage. Then I can play with her/his money for small stakes at first. If successful, we can move on to larger stakes (I saw a $5,000 table max. in Shreveport.).
Alternately, I could try to demonstrate this Ace prediction by hiring a dealer to deal me cards while interested parties watch live via Skype.
Besides the fact that my samples have been extremely small (even though I got very similar results replicating a couple of times), any thoughts?
