Question

How do you know when to bet high when counting cards in a K-O system?

Answer 1

Don't do it.

Answer 2

The simple answer is that you bet higher when you have an edge over the house.  When is that?  That occurs when your running counting indicates that you've exceeded a particular threshold, that threshold being related to the number of decks being played.  (Also called a 'key' count.)  I recommend http://www.koblackjack.com/K-O_Rookie_Sy... for a fuller explanation but note that there are many types of "Knock Out" system.  (I myself prefer the traditional balanced KO systems, i.e., the '7-card' is given a value of zero.)
