The book is old and outdated tactics, George was not even a long time BJ player prior to writing the book and he stats so in his book. He is certainly not a authority on such a topic. For hahas I tested 2 runs of 1,000 hands each, All of which had short term positive winnings along the 1000 hand road. But in the end the 1st 1000 round I was 23 chips ahead, the 2nd 1000 hand round I got much of the same at 49 chips ahead
