Norm, there is something I don't get.

In CVData, do you count all Aces ? Or only "Aces you can see" (at this moment) ?
to which you reply: Aces you have seen

When using KO and taking an insurance decision, it's fine to adjust the count with the Aces on the table at that moment (could say the same for Hi-Lo). However, if you require the player to take into account all the Aces played, this isn't KO anymore because the KO count doesn't have a sidecount of Aces. A KO player will choose this system for its simplicity and certainly not to sidecount Aces.
