What I have always found easiest to do in a DD game is to attach a letter to the count.
As each Ace is played you add the next letter in sequence - from A to H and use Z when NO ACES have been seen.
e.g. If in my head I am at 4B I know that my running count is +4 and I have seen 2 Aces. Each quarter deck is normalized at ONE (1) ACE. In this case, I have seen 1 deck. That would be 4 quarters and 4 Aces depleted would be normal, but I have only seen 2. So I am "rich" by 2 Aces. The R.C. and T.C. are the same as one deck has been viewed. NOW for betting purposes, (using Hi-Opt II), I add 2 x 2 = 4 to the count. As I am then at +8. I place a substantial bet.
Now I need to play my hands and SOME hands, (mostly doubles and splits), are effected by the Ace "richness" Most are not, and for them I MUST use indices keyed to +4, that is to say - the original unadjusted T.C..
So, for example, I play and I get Ace-8 The dealer shows a 4.
The Index of +4 is not enough to double this hand, [I need +7]
My adjusted Index of +8 is sufficient to double this hand. I do so.
The Pit Critter is grinning as he thinks that i am wildly overbetting AND misplaying my hands. He only knows Hi-Lo of course.
Another example: 7-7. The dealer flips over an 8. the extra Aces hurt as they are more beneficial to the dealer than they are to me. I am beyond the +3 that I would need to split here BUT here I must change direction and NOT add +4 for the Ace "richness" but SUBTRACT 4. Plus 4 and Minus 4 cancel each other out. I now play the hand as I would at a ZERO T.C.
If the dealer had a 6, I'd split my 7's with glee because the extra Aces make my potential 18's powerful against the dealer's likely 17.
A bit later things change. You are again at the one deck of two penetration point (keeping this simple) and your count is +8H The "H" tells me that there are no more Aces available until the shuffle (and sets up a nice shuffle-tracking scenario as well)
Ordinarily TC +8 would call for a Max bet (or nearly so), but with ALL 8 Aces played, the count is adjusted by [2] x [−2] = −8. Ergo +8 + [-8] = 0
In spite of the pit critter's counting along with you and imagining that you ought to be betting a few units, you bet the minimum, or Wong-Out.
Good and effortless camo'
You now have a neutral count and your doubles on eleven are enhanced because you cannot get an Ace for an ugly 22; your doubled 10's, 9's, and 8's are weakened for obvious reasons. Your (better) soft doubles are weaker than usual. The dealer's Faces and 9's, and 8's become less threatening. Your splits tend to be weaker for 6-6, 7-7, 8-8, and 9-9.
SO … where the Aces are helpful you will adjust your play to a True Count of +16 and where they are detrimental to you (because the lack of them assists the dealer) you would use an adjusted T.C. of 0
