Side Count Aces
"Whats the best way to use side count of aces? For insurance only to get an accurae count of the tens that still are in the deck?"
It can help in some cases for that, yes. The main reason to side count or side track Aces is for betting purposes.
"Do most pros count aces?"
It seems less and less people side Aces as time goes by. The Hi Opt II by Ph.D. Lance Humble is a great example of the Ace side count. Ustons APC perfected tracking Aces per quarter deck. The new "pros" will tell you that it is too difficult for what you will gain from it. If you can't do it, then it makes no sense, but if you can, it will give you a better edge. I think most of the real pros use Hi Opt II but will not tell you they do. It's an anti-Canadian conspiracy (Humble is Canadian), similar to the Avro Arrow scam....grin
