Dubner Count
I was reading through a 2003 article in BlackJack Forum about Darryl Purpose where he states that the Dubner count was first released in 1959. I am familiar with the first publication of Basic Strategy around 1957 and the Dubner count in Thorp's revised 1966 edition but no mention of this count preceding Thorp's 1962 book. Does anyone have any information on this 1959 paper?
