Basic strategy is based on your 1st 2 cards and dealer up card, Ihave been playing my first 3 cards for soft counts on the same basis, obviously without being able to double

Example: I have a 2, 4 showing, dealer has 6 ... I get an A so soft 17, I have been hitting ... is this right> Any cheat cards based on 1st 3 cards?

I am still play min $10, inc bet $5 each tc +1 for +2 or higher, Dealer hits soft 17, ASM, 6 Decks, Double after splits, Split 3 times, only 1 card each after splitting aces, double on 1st 2 cards only,
