Is there ever a time when the dealer up card is 5 or 6, and the count is high enough to make putting out more money, double down, on an A,9 a good play? When you are dealt a hard 10 you always double under these conditions. You may not improve your soft twenty, but heck, your banking on the dealer to bust anyway, right?
Double down on soft 20?

Yes +4 in KO vs 5 and 6. Same with splitting 10s. Regardless of your system I believe that you can double (and split tens) at a true edge of +2 v 5,6 and then +3 v 4,3 and then +4 v 2. Notice those plays are to be made at your true edge and not your true count.
Both 5 and 6 are +5
12 vs 2: 2
12 vs 3: 1
12 vs 4: 0
12 vs 5: -1
12vs 6: -1
13 vs 2:-1
13: 3: -2
15 vs 10: 3
16 vs 9: 4
16 vs 10: 0
9 vs 2: 1
9 vs 7: 3
10 vs 10: 5
10 vs A: 4
11 vs A: 1
Splitting 10’s
10,10 vs 5 and 6: 4
Insurance: 3
You don't need to learn seperate set of indexes for different number of decks since Hi-opt 1 is a balanced count.

Im not sure about other countires, but in Australia, you dont have a choice with blackjack, same as 21
Here is an easy remember the soft double downs on 20 and 19, what I like to call "6 to 4, is +6 to +1"
S20 vs. 4.....5.....6 ....S19 vs. 4......5.....6
.........(+6) (+5) (+4)..........(+3) (+2) (+1)
Easy huh? memorizing every single index is really hard (and not very effective), so I break them down like this and memorize them a little bit at a time. There are also indexes for doubling on S20 and S19 vs 2 and 3 but it is very rare that you will see those high counts.
S19 vs 5 is actually +1 but the above mnemonic is an easy way to keep it in mind.

S20 vs. 4.....5.....6 ....S19 vs. 4......5.....6
.........(+6) (+5) (+4)..........(+3) (+2) (+1)

If I ever doubled down on a soft 20, everyone at the table would simoultaneously beat me to death.
When I do something like split 9's they flip, so if I did that or split 10s, my life would be over faster than the Detroit vs. Kansas City game.

It is a great way to get rid of people :devil:

Hey supercool
Correct me if I am wrong, but I do not see in the KO book where it says to dd on s20 @ +4, or to split 10's.
thnx

They aren't in the book. There are more indexes than the book lists. In order to find them you have to do a simulation or get them from someone else who has.
Agreed! But you actually win either way. They get annoyed by you and leave, yay, higher expectation. Conversely, if you strike up a relationship they sell you some great hands. This is extremely prevalent in the Korean casino I play at. Anyone for buying a player BJ vs Dealer A by giving the guy even money when the count is neutral or even better, negative? Or how about buying a 13 vs 8 for surrender price, because my "new friend" doesn't want to play it. I get these all the time, and life is good

those are some good points. for me the idea of making friends (talking local casino here) is useful. it's part of my cover. if the pit likes you and the other locals like you i believe the pit will find it a harder decision to show you the door.
still like all cover plays one wants to keep the bottom line in mind.... money.

A good point. If you are contantly clearing their tables of their "good" customers, you will be shown the door the second they suspect you of advantage play.
