If you continuously drill the cards you will learn the entire "set of plays" for the hand. I expand the matrix on the card if I want to add something new (ENHC, NDAS). Next step for me is adding SHOE/DD split to the H17/S17 columns. I find that once you have learned everything completely it's not bad to add on new information, or add a new card to widen your indices.
Nice.

Thanks for any input.
I've got a spreadsheet with 7 tabs for the different Blackjack rules(1,2,6 decks) and Spanish which includes BS charts and indices.

If my mind gets a little foggy on the road, I can look at the spreadsheet on my phone before I enter the casino or during a bathroom break.

I don't play many games with S17 rules. So the week before a trip that will include these rules, I will do drills on the differences between H17 and S17 rules.

It is really not much work to learn the appropriate basic strategies and index play deviations for multiple rule sets.

After reading through all the EV tables you’ll notice some deviations for H17 vs S17 aren’t worth much at all and likely increase variance. A7 vs 2, 11 vs A, A8 vs 6 come to mind. You’re going to do these deviations anyway at +1 or higher counts.

The surrender options are important. In H17 you must remember to surrender 15, 8/8, and 17 vs A. Stand 17 vs Ace is an index IIRC for H17 at higher counts.

We have an illustrious member who posts good info, who also owns/runs Blackjack Science. Surely you guys have heard of the MIT guys and the "mad russian"....LOL How about starting with something that he is nice enough to give the public for free on his site. And if you purchase something else, you are helping the cause......so to speak. But it's a good place to start without recreating the wheel. Not a promo.........just appreciate that he is helpful.
