Hmm ...
They may well be pros. But they do not, I think, practice ace location professionally.
Hmm ... don't you be getting me into a distinction between a professional who ace sequences and a professional ace-sequencer.
That would just be annoying.
:)
Though, to be clear, my understanding is that professional ace sequencing fell out of favor, for the most part, years back in the US once it became a known technique.
Small misconceptions they have about some of the practicalities of the art make that clear. They are obviously intelligent people who could make money at other forms or methods of gambling.
Insofar as Mathboy and Radar are concerned, My impressions are they may sequence under favorable circumstances, but these are so few and far between ... they rely on other methods to gain an advantage.
That said, I have not met these gentlemen, so its best I not speak on their behalf.
For me, it was Radar's review,McDowell's Blackjack Ace Prediction: A False Key to Shuffle Tracking actually, that I felt conveyed in very real, human terms, the difficulty in finding an ace to put money on.
Particularly near the end when Radar states:
If you�re playing at low-stakes, in the U.S., the more you learn from observation what to do and the more skilled you get, the more frustrated you will get because you will so rarely get an ace you can actually bet on. You may even give up on ace location because you�re not making enough money from it to justify all your work.
However, if you feel there were misconceptions in that article, it would be most interesting to hear them. I'm sure Radar would enjoy discussing them, as well.
