Until I see all the cards to make my final count for the round:
For playing decisions during a round, when dealer upcard is 2 through 6, I count the unseen cards in a hand as +1 if the hand is hit. If the dealer's upcard is 7 through A, I count each pat hand as -1.
Also, see Stanford Wong, "Blackjack Secrets", page 63.
It is difficult to interpret exactly what you are trying to ask by the way you phrased this question. It sounds as if half of the question pertains to basic strategy for 2 decks, and the rest about how to properly count cards using the Hi-Lo system. I think you will get a more precise response from the resident experts if you were to rephrase the question. Stanford Wongs' book Professional Blackjack is the most comprehensive Hi-Lo book on the market; it is an invaluable Question/Answer/Reference tool for the Hi- Lo counter and can be found under the "Our Catalog" link above. Good luck!
I apreciate your reply along with the other responces .I would be indebted to you if you could furnish page 63 in blackjack secrets book I intend to purchase book but i am goig on trip latter part of week and have no time to get it if you could fax it to me or tell what page says thanks ray
I hesitate to send more without permission from the author Wong.
But, as you know, there are other ways to estimate what the other
players' cards are. One way is to ask the other players to show their cards. Sometimes a congenial table will show one another their cards before taking insurance.
Recently, I was playing beside a gentleman who stated that he always insured 10-10, so when he insured later, I subtracted two off the count. Later, he insured and said "the dealer has had blackjack every time and I'm insuring", so I counted that as 0.
Your mileage can vary. For example, recently, the other 3 players tucked. Less than one deck remained to be dealt, with my max bet out. I inferred a true count of +1 and did not insure. But they had 9-6, 9-6, 8-8, totaling a +2 instead of the -3 that I inferred! I had seen they were not strong players, but that was a shock.
