Blackjack KO Card Count

blackjack card counting

The blackjack KO card counting strategy is the simplest counting system that has been introduced to the game of blackjack and anyone should be able to execute the running count. The only different from this system and the hi/lo counting strategy is that this is an unbalanced count which means that the total count doesn't equal 0 after counting through the entire deck. The reason it's unbalanced is because in this counting system 7's equal +1 instead of 0 like in the hi/lo system.

This strategy for counting cards is the most widely used unbalanced counting strategy in all of blackjack and many blackjack players use this system everyday while playing cards. It's not very difficult to count cards in blackjack because the game is fairly slow paced and you can see all the cards in front of you at every point during the hand. Some of the systems which have been used are a lot more difficult then the KO card counting strategy though, which makes this the best strategy for new players or anyone having trouble with counting cards.

The pros recommend that this strategy is only used by beginner blackjack players who are just learning how to count cards. It's the easiest method to learn and all the other card counting systems are similar so once you get this one working you can move on to more difficult systems. The more difficult the system is for you to count the more accurate it typically will be, so it's important you learn more advanced strategy once you're comfortable with this one.

By looking at the card value chart above you can see that there isn't much you need to remember. If you can remember that the low cards are +1 and the high cards are -1 then you should be good. The toughest two numbers to remember are the eights and nines due to them being worth 0 so make sure you don't mess this up because it will flaw your running count.

As the cards go by, you need to keep a running total in your head. The higher the total in your head, the more you should bet. The lower the total count, the less you should bet. i.e. A count of +20 is very good for the player, and you should bet anywhere from 5-10 units. A count of -20 is very good for the house, and therefore very bad for the player, so either bet 1 unit at a time, or get up a take a break.
