hello, ive just finished reading arnold synders 'blackbelt for blackjack', great book!!!am in the process of learning the red7 count, will eventually be memorizing the advanced strategies to increase profitability,

My question is about the strategies table in the book for advanced red 7 count, in the table it says when u have 11 versus dealer Ace, on a count of
-4, if am understanding it correctly, you show hit(-4,-5,-6 etc) and double down on (-3,-2,-1 etc), is this correct??????

Also,do i use these advanced strategies on all tables, with varying rules etc, are they universal throughout most games(obviously there will be stinking games with bad rules that i wouldnt even entertain trying to count) i.e amsterdam airport, no push rule!!!!!!!!!! what a joke!!!!!!

any help would be welcome.

thanks
