The Knock-Out Counting System (a.k.a. the Unbalanced Knock-Out System or the KO Count), was invented by Ken Fuchs and Olaf Vancura Ph.D and was branded as the "Easiest Card Counting System Ever Devised".

It was one of the first "unbalanced" counts. A system where totaling the values of all of the cards in a deck resulted in a number other than zero.
