A,7 Vs Dealer's Ace

[ssho88]

What is the correct BS for player A,7 against dealer's Ace ? Hit or stand?

What is the index or BS variation for this hand?

The rules are 4 decks, S17, D9, DAS, ES10, BJ pay 3:2, ENHC, penetration = 60%,no surrender against dealer's Ace, RSA to Max 3 hand.

Straight BS calls for a hit with an A/7 against a dealer Ace in every variation I have sharts on EXCEPT Single Deck where S17 (then you stand).

Mike is right. Basic strategy is to hit (A,7) vs Ace. The only exception is single deck when the dealer stands on all 17s. In that game, BS says stand.

When the dealer hits soft 17, this is not a close call at all. Wong gives the index number for single deck H17 at +17. He does not provide an index number for 4 decks, which means the value is higher than +20.

In an S17 game, this is a much closer decision. In one deck, the index is 0. In 4 decks, the index is +1. So, stand at +1, hit at anything lower.

Ken, I have yet to see an index move 17 points because of a H/S 17 variance. Is something amiss with Wong's calculations or have I been smoking too much of Mike's hooch? To quote Revere:"If the dealer hits S17, stand on A7 v. A if TC=>+1" Sounds like a good sim exercise.

Standing on a S18 is bad but not THAT bad on a multideck. The index for standing is +1 for 4 or more decks, but a WHOPPING +17 for single deck. So definately stand with a single deck.

The index moves as it does mainly based upon how often a dealer will have a soft 17 and stay in the S17 game. Besides having a six in the hole, any time a dealer has an A-5 in the hole there is the possibility he will land up with soft 17.
I do not have the math to know if this should move the indice 17 points but instinctively I know it would be a significant move.
