How about this: Using HiLo with an ace side count for single deck games. When you bet, you do so based on the TC. When it comes time to make a playing decision when an ace would help you (e.g., A,8 v 6) then you use the TC as is to decide whether to stand or double. But if you have a hand where an ace would hurt you (e.g., 5,6 vs 10 or A) you subtract the remaining aces from the RC, convert to an adjusted TC and then make the decision base on the adjusted TC. Assuming the SD game was worth playing in the first place, would this method be worth the trouble for whatever playing efficiency you gain?
