I was playing last night with this fellow who kept insisting to me that he was right to double down on an 8 vs a dealer 6 in an 8 deck game when the count wasn't good. I asked him why he thought that was a good move. He then shows me this basic strategy chart from this so called book that he made a copy of. I'm looking at him and telling him, that must be for single deck. He insists it's for multiple decks. Can anyone verify that this book is indeed printing misinformation out?
